X-ray diffraction and thermo gravimetric analysis of surface modified areca sheath fibre epoxy composites

Focus of the current study is to shed more light on thermal behaviour of composites made up of areca sheath fibres. The XRD analysis revealed that crystallinity index and crystallinity percentage increased with different treatments, as it leads to better interaction of fibre and resin. The crystallinity percentage of alkali treated fibre and benzoyl peroxide treated fibre increased by 5.87 and 8.44% respectively compared to untreated fibre. This was further evident in thermo studies which proved better thermal stability in benzoyl peroxide treated fibre composite.

Bionic design of thin-walled tubes inspired by the vascular structure of bamboo

In order to improve the crashworthiness and energy absorption of thin-walled tubes, this work proposes a novel design inspired by the vascular fiber sheath flap (VF) and central through-hole characteristics of bamboo vascular bundles. The energy absorption of the bionic structure is verified by experiments and theoretical analysis. Numerical simulations are used to analyze the effect of bionic unit structure and connection settings on various crashworthiness indexes. The results show that the bionic tube achieves the optimal energy-absorbing structure when the VF unit is a semicircle and the ratio of the circle core’s radius to the straight panel’s length is 3:7. Further, the effect of connection between the bionic unit and the outer tube on crashworthiness is also explored, and the optimal αβ-connection is obtained. Finally, both parallel fractal(PF) and rotational fractal(RF) approaches are introduced to improve the crashworthiness of thin-walled tubes based on the optimal structures obtained. And the crashworthiness of PF tube is better than that of the RF tube under the same level.

DEVELOPMENT AND CHARACTERIZATION OF HEMP-CONTAINING HYBRID YARNS FOR CLOTHING

"Known for its sustainable properties, the usability of hemp instead of conventional cotton hybrid yarns for clothing was investigated by spinning hybrid ring yarns using conventional cotton, viscose-hemp, and organic cotton-viscose-hemp blends for the sheath and elastane and polyester (Lycra and T400) for the core in the yarn structure. Unevenness, yarn imperfections, hairiness, tenacity, and breaking elongation properties of the spun hybrid yarns were examined comparatively by statistical analysis methods. The findings revealed that sheath fiber type, number of components in the yarn structure, and blend ratio were influential factors on yarn quality. Using hemp fiber in the yarn structure slightly decreased the yarn properties, except for tenacity, in general. This situation was more visible in hybrid yarns, which have three different fibers in the sheath. Blending viscose and hemp fibers in the yarn sheath structure provided a synergetic effect, improving the weak properties of both fibers. These yarns had nearly the same tenacity values (from 12.98 to 15.47) as conventional cotton yarns (from 15.24 to 16.8), which could be explained by the fact that hemp fiber has a higher tenacity value (45 cN/tex) than other fibers. Moreover, these yarns had the highest elongation values (from 15.88 to 10.79) due to the good elongation properties of the viscose fibers (20%), compared to other sheath fibers. As a result, when the produced yarns were evaluated in terms of sustainability and performance, viscose-hemp-blended yarns had the optimum yarn properties."

Differences in dry shrinkage of bamboo rings with multiple heights and radians based on vascular bundle group

Abstract Moso bamboo is widely used in production due to its high strength-to-weight ratio, fast growth and renewability. Meanwhile, bamboo’s dimension is highly sensitive to moisture, resulting in cracking and other defects easily. This study aimed to investigate the changes in cracks, bamboo ring shapes, fiber sheath area and volume fraction, and vascular bundle group shapes from the green state to the absolute-dry state, using the target detection model and Python fitting technique. The results showed that the radius of the vascular bundle group increased while its radian and arc length decreased with a decrease in the moisture content. The decrease in the cross-sectional area was greater than that in the wall thickness and arc length. The dry shrinkage of the fibers was greater than that of the rest tissues, which was an important part of the shrinkage of bamboo rings. Obvious cracks mainly appeared in the bamboo ring with a complete radian of 2π, while almost no or very limited cracks were seen in other rings with incomplete radians. This study further elaborated on the dry shrinkage changes and differences in bamboo rings, which might be beneficial to restrain the deformation and cracking of bamboo products effectively.

Analysis of the Performance of Natural Composite Materials Reinforced with Sago Sheath Fibers as an Alternative Material in Overcoming the Effect of Urban Heat Islands on Buildings

Local knowledge of a region is an asset that encourages the identification of a region. Hence, the specificity, uniqueness, and character that animates a particular city can distinguish it significantly from other cities. Sago tree fronds are widely applied to buildings as an alternative material for making tiles for roofs and other parts of buildings. The sago palm has long been used for making roofs and walls, especially in traditional houses. Few previous studies have used sago fronds as a manufacturing material for traditional houses. However, based on data in the field, many traditional houses still use sago fronds as a roof and wall framing material. This is also an effort to overcome the urban heat island phenomenon (UHI) in buildings. The UHI phenomenon is a phenomenon of urban development that highly affects environmental quality conditions and causes microclimate changes where air temperature conditions in urban areas are higher than the surrounding air temperatures. Sago midrib fiber is a natural composite material used as a reinforcing material for natural composite materials due to its thermal and mechanical properties. Composite materials using the hand lay-up technique—with characterization methods including the impact test and the DSC test, variations in NaOH levels, and variations in the resin–catalyst matrix—were used in this study. The results obtained were then compared with those in the literature. The results showed that 6% NaOH obtained the most significant impact value of 2.1 J, and the resin–catalyst matrix variation of 97.5%:2.5% obtained the most significant impact value, which was 2.4 J. Meanwhile, the DSC test results showed that the material’s best value for retaining heat was at 4% NaOH content variation and a resin–catalyst matrix variation of 97.5%:2.5%.

Investigation of Cell Adhesion and Cell Viability of the Endothelial and Fibroblast Cells on Electrospun PCL, PLGA and Coaxial Scaffolds for Production of Tissue Engineered Blood Vessel.

Endothelialization of artificial scaffolds is considered an effective strategy for increasing the efficiency of vascular transplantation. This study aimed to compare the biophysical/biocompatible properties of three different biodegradable fibrous scaffolds: Poly (ɛ-caprolactone) (PCL) alone, Poly Lactic-co-Glycolic Acid (PLGA) alone (both processed using Spraybase® electrospinning machine), and Coaxial scaffold where the fiber core and sheath was made of PCL and PLGA, respectively. Scaffold structural morphology was assessed by scanning electron microscope and tensile testing was used to investigate the scaffold tension resistance over time. Biocompatibility studies were carried out with human umbilical vein endothelial cells (HUVEC) and human vascular fibroblasts (HVF) for which cell viability (and cell proliferation over a 4-day period) and cell adhesion to the scaffolds were assessed by cytotoxicity assays and confocal microscopy, respectively. Our results showed that all biodegradable polymeric scaffolds are a reliable host to adhere and promote proliferation in HUVEC and HVF cells. In particular, PLGA membranes performed much better adhesion and enhanced cell proliferation compared to control in the absence of polymers. In addition, we demonstrate here that these biodegradable membranes present improved mechanical properties to construct potential tissue-engineered vascular graft.

DEVELOPMENT OF SUSTAINABLE AND ECOLOGICAL HYBRID YARNS: HEMP FIBER IN DENIM FABRIC PRODUCTION

This study aims to develop and characterize more sustainable and ecological yarns as an alternative to 100% cotton in traditional denim fabric production by using hemp fiber. For this purpose, conventional ring, core-spun and dual core-spun yarns were spun from three blend proportions of organic cotton/hemp fibers as 100:0, 80:20 and 70:30 in percentages. Hemp and organic cotton were used as sheath fiber, and elastane type (Lycra and T400) – as core fiber in the yarn structures. According to the results, the sheath fiber type and blend ratio greatly influenced all yarns’ physical characteristics. Using hemp fiber in the yarn structure generally decreased the yarn properties, as expected. However, the best results by using hemp fiber in the yarn structures were achieved by using 20% hemp fiber in the sheath of the yarn structure. Further increasing this rate to 30% worsened the yarn properties considerably, regardless of the core component. When the yarns were evaluated in terms of sustainability and performance, 80/20% organic cotton/hemp blended yarns had the optimum yarn properties.

Vascular bundle characteristics and mechanical properties of Dendrocalamus sinicus

Understanding the structure and mechanical properties of the material is a prerequisite for exploiting its potential. Here, this study aims to investigate the basic information and distribution characteristics of the vascular bundles and mechanical properties of Dendrocalamus sinicus to provide theoretical and technical guidance for its exploitation. Nanoindentation, macro-mechanical tests and a recognition model based on the YOLO algorithm developed by the group were used to reveal its structure, micro-mechanics and macro-mechanics. The results revealed that the length, width, length-to-width ratio (The ratio of the length to the width of a single vascular bundle) and area of individual vascular bundles were distributed with a quadratic function along the radial direction, and the mean values of both fiber volume fraction and area of fiber sheath were high, reaching 34.11 % and 0.3301 mm2, respectively. The nanoindentation measurement showed Dendrocalamus sinicus had excellent mechanical properties with an indentation modulus of elasticity of 24.10 GPa and a hardness of vascular bundles of 626.03 MPa. Dendrocalamus sinicus consisting of a large proportion of high-strength fiber sheaths made it highly significant to exhibit excellent macro-mechanical performances, suggesting that Dendrocalamus sinicus has a huge potential for exploitation and can be used as materials for furniture, construction and other fields. It has the potential to replace traditional building materials such as steel and concrete in the future.

Experimental Investigation on Density and Volume Fraction of Void, and Mechanical Characteristics of Areca Nut Leaf Sheath Fiber-Reinforced Polymer Composites

Natural fiber-reinforced polymer composite is a rapidly growing topic of research due to the simplicity of obtaining composites that is biodegradable and environmentally friendly. The resulting composites have mechanical properties comparable to synthetic fiber-reinforced composites. In this regard, the present work is formulated with the objectives related to the development, characterization, and optimization of the wt% of reinforcements and the process parameters. The novelty of this work is related to the identification and standardization of the appropriate wt% of reinforcements and parameters for the processing of the areca nut leaf sheath fiber-based polymer composites for enhanced performance attributes. With this basic purview and scope, the composites are synthesized using the hand layup process, and the composite samples of various fiber compositions (20%, 30%, 40%, and 50%) are fabricated. The mechanical characteristics of biodegradable polymer composites reinforced with areca nut leaf sheath fibers are investigated in the present work, with a focus on the effect of fiber composition (tensile properties, flexural strength, and impact strength). The properties of composites are enhanced by combining the areca nut leaf sheath fiber and epoxy resin, with a fiber content of 50% being the optimal wt%. The Scanning electron microscopy (SEM) investigations also ascertain this by depicting the good interfacial adhesion between the areca nut leaf sheath fiber and the epoxy resin. The tensile strength of the composite specimen reinforced with 50% areca nut fiber increases to 44.6 MPa, while the young’s modulus increases to 1900 MPa, flexural strength increases to 64.8 MPa, the flexural modulus increases to 37.9 GPa, and impact strength increases to 34.1 k J/m2. As a result, the combination of areca nut leaf sheath fiber reinforced epoxy resin shows considerable potential as a renewable and biodegradable polymer composite. Furthermore, areca nut leaf sheath fiber-reinforced epoxy resin composites are likely to replace petroleum-based polymers in the future. The ecosustainability and biodegradability of the composite specimen alongside the improved mechanical characteristics serve as the major highlight of the present work, and can help the polymer composite industry to further augment the synthetic matrix and fiber-based composites with the natural fiber-reinforced composites.

Elastomeric Core/Conductive Sheath Fibers for Tensile and Torsional Strain Sensors.

Motion sensing, aimed at detecting and monitoring mechanical deformation, has received significant attention in various industrial and research fields. In particular, fiber-structured mechanical strain sensors with carbon-based materials have emerged as promising alternatives for wearable applications owing to their wearability and adaptability to the human body. Various materials, structures, sensing mechanisms, and fabrication methods have been used to fabricate high-performance fiber strain sensors. Nevertheless, developing multi-modal strain sensors that can monitor multiple deformations remains to be accomplished. This study established core/sheath fiber multi-modal strain sensors using polymer and carbon nanotubes (CNTs). Specifically, a flexible and conductive CNT sheet was wrapped onto the elastomeric core fiber at a certain angle. This wrapping angle allowed the CNTs to mechanically deform under tensile and torsional deformations without fatal structural damage. The CNTs could sense both tensile and torsional strains through reversible structural changes during deformations. The fiber strain sensor exhibited an increase of 124.9% and 9.6% in the resistance during tensile and torsional deformations of 100% and 1250 rad/m, respectively.

Polylactic Acid (PLA) Reinforced with Date Palm Sheath Fiber Bio-Composites: Evaluation of Fiber Density, Geometry, and Content on the Physical and Mechanical Properties

ABSTRACT Significant interest for utilizing and processing natural fibers (NF) to develop sustainable and fully biodegradable composites evolved as the global environmental concerns upsurge. Date palm tree (DPT) accounts for more than 2.8 million tons of waste annually, making it the most abundant agricultural biomass waste in the MENA region. This study investigates the effect of date palm fiber (DPF) density, diameter size and content on both the mechanical and physical properties of polylactic acid (PLA) reinforced DPF bio-composite. The bio-composites are developed using melt-mixing technique which is followed by compression molding. The influence of the mechanical properties is investigated by evaluating the tensile, flexural and impact strengths. Meanwhile bio-composite thickness swelling (TS), moisture content (MC) and water absorption (WA) characteristics are evaluated. Bio-composite microstructures are examined using SEM to investigate the interfacial bonding between PLA matrix and DPF. Results showed that at 40 wt.% DPF, the TS, MC, and WA were the highest demonstrating an increase of 4.10%, 4.95%, and 8.22%, respectively. Although the results demonstrated a decrease in mechanical properties as DPF content increased (depending on DPF geometry), the results indicate that the developed technologies could be commercialized under the waste management scheme for non-structural applications.

Dry shrinkage of Moso bamboo in relation to vascular bundle structure

Abstract Bamboo is susceptible to moisture-induced dimensional instability and cracking. Combining traditional methods with vascular bundle detection, the coordinates and fiber sheath area of each vascular bundle was determined accurately. Based on data fitting, the change in the shape of cross-section was quantified and analyzed based on parameters such as radius, radian, and arc length. The changes in the total area and the areas of different types of fiber sheath, as well as the changes in the arrangement of vascular bundles were studied. The results showed that when the moisture content was reduced from 64% to 0%, the radius of the cross section was increased by 21%, while the radian and arc length decreased by 22% and 6%, respectively. The fibers shrunk by 15%, which was greater than that of the other tissues except bamboo fibers (9%). The gradient distribution of the fiber volume fraction contributed to its asynchronous dry shrinkage. Significant radial and tangential displacements were found in vascular bundles. This work further elucidated the dry shrinkage mechanism of bamboo, and was of great significance for the quantitative analysis of changes in bamboo structure from a combination of micro and macro perspectives.

Hydrophilic Core-Sheath fibers of polyvinyl alcohol / polyethylene composites through in situ ethylene polymerization

Core - sheath fibers of polyvinyl alcohol/polyethylene composites are synthesized by ethylene polymerization with titanium tetrachloride incorporated PVA nanofiber (NF) as catalyst precursor in presence of methyl aluminoxane (MAO) as a cocatalyst. The process also involves the initial preparation of PVA nanofiber by electrospinning followed by its reaction with titanium tetrachloride. The obtained titanium incorporated PVA was found to be insoluble in protonic solvent due to the reaction of OH group in PVA with titanium tetrachloride leading to the formation of a cross-linked mat. Thermal analysis of core-sheath fiber composite indicated the presence of polyethylene due to observation of melting peak at 134 °C. PVA-PE fiber composite is characterized by FTIR, SEM, and contact angle data. The results demonstrate that the presented approach is useful for synthesizing incompatible classes of polymer composite fibers such as polyvinyl alcohol/polyethylene with core-sheath morphology.

Study of Treatment Effect on the Cocos Nucifera Lignocellulosic Fibers as Alternative for Polymer Composites

ABSTRACT The usage of new cellulosic fibers in industrial applications is massive because of its excellent performances. These fibers are utilized especially for manufacture of high-performance composites. Coconut leaf sheath (CLS) fibers are extracted for leaf sheath of coconut tree. The aim of this paper is to study the possibility of using a natural fiber CLS as an alternative for polymer composites. In the current study, the consequence of NaOH treatment on structural, thermal and morphological behavior of treated and untreated coconut leaf sheath (CLS) fiber in terms of single fiber tensile strength, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (×RD), thermogravimetric analysis (TGA) and differential scanning calorimeter (DSC) has been explored. From SEM analysis, it was identified globular lumps spread consistently over the fiber which could help the mechanical interlock with the resin. The outcomes from the experimentation exposed that the NaOH treatment has impacted in the eradication of amorphous hemicellulose and lignin contents from the CLS fiber surface and in turn resulted in excellent structural and thermal stability behaviour of fiber. The present work endorses the great potential of CLS fibers to be utilized for bio-reinforcement in order to fabricate lightweight composite structures, employed in automobile and structural applications.

Green synthesis of cellulose nanocrystal/ZnO bio-nanocomposites exerting antibacterial activity and downregulating virulence toxigenic genes of food-poisoning bacteria

Recently, cellulose nanocrystals (CNs) have attracted wide attention owing to their superior properties compared to their bulk materials. For example, they represent an outstanding model for fabricating green metallic/metal oxide nanoparticles (NPs). In this study, two CNs (carboxylated CNs and sulfated CNs) extracted from agro-wastes of palm sheath fibers were used as templates for the facile and green synthesis of ZnO NPs by employing the sono-co-precipitation method. The obtained nanomaterials were characterized using TEM, EDX, UV–visible, DLS, FT-IR, and XRD analysis. As a result, the size and concentration of synthesized ZnO NPs were inversely proportional to one another and were affected by the CNs utilized and the reaction temperature used. Contagious diseases incited by multifarious toxigenic bacteria present severe threats to human health. The fabricated bio-nanocomposites were evaluated in terms of their antimicrobial efficacy by agar well diffusion method and broth microdilution assay, showing that CN–ZnO bio-nanocomposites were effective against the tested Gram-negative (Escherichia coli and Salmonella) and Gram-positive (Listeria monocytogenes and Staphylococcus aureus) bacteria. The influence of the subinhibitory concentrations of these suspensions on the expression of the most critical virulence toxin genes of the tested strains was effective. Significant downregulation levels were observed through toxigenic operons to both fabricated CN–ZnO bio-nanocomposites with a fold change ranging from 0.004 to 0.510, revealing a decline in the capacity and virulence of microorganisms to pose infections. Therefore, these newly fabricated CNS–ZnO bio-nanocomposites could be employed rationally in food systems as a novel preservative to inhibit microbial growth and repress the synthesis of exotoxins.

CAMP and the Fibrous Sheath Protein CABYR (Ca2+-Binding Tyrosine-Phosphorylation-Regulated Protein) Is Required for 4D Sperm Movement

A new life starts with successful fertilization whereby one sperm from a pool of millions fertilizes the oocyte. Sperm motility is one key factor for this selection process, which depends on a coordinated flagellar movement. The flagellar beat cycle is regulated by Ca2+ entry via CatSper, cAMP, Mg2+, ADP and ATP. This study characterizes the effects of these parameters for 4D sperm motility, especially for flagellar movement and the conserved clockwise (CW) path chirality of murine sperm. Therefore, we use detergent-extracted mouse sperm and digital holographic microscopy (DHM) to show that a balanced ratio of ATP to Mg2+ in addition with 18 µM cAMP and 1 mM ADP is necessary for controlled flagellar movement, induction of rolling along the long axis and CW path chirality. Rolling along the sperm’s long axis, a proposed mechanism for sperm selection, is absent in sea urchin sperm, lacking flagellar fibrous sheath (FS) and outer-dense fibers (ODFs). In sperm lacking CABYR, a Ca2+-binding tyrosine-phosphorylation regulated protein located in the FS, the swim path chirality is preserved. We conclude that specific concentrations of ATP, ADP, cAMP and Mg2+ as well as a functional CABYR play an important role for sperm motility especially for path chirality.

A remarkable new species of Davilla Vand. (Dilleniaceae, Dolicocarpoideae) from the Brazilian Savanna supported by morphological and anatomical data

Davilla pygmaea, a new species endemic to the Brazilian Savanna, is described, illustrated and its systematic position is discussed here. The new species is closely related to D. elliptica and D. grandiflora, from which it differs by characters such as a decumbent habit, the shape of its leaf blades, the inflorescence architecture, the size and numbers of flowers, the size of the internal and external sepals during flowering and fruiting, the androecium with 126-131 stamens, and the presence and type of trichomes on vegetative organs. Anatomical characters such as the number of vascular bundles in the petiole and midrib, shape of the midrib in cross section, the margins of the leaf blades, the presence and arrangement of the fibers associated with small-caliber vascular bundles, and the presence of a fiber sheath extension in studied species also differentiate them. Histochemical tests demonstrated that alkaloids, acidic lipids, and phenolic compounds present in the leaf tissues of the new species and D. grandiflora, its closest congener, may have potential medicinal properties. In addition, the new species has its distribution mapped, its flowering and fruiting seasons delimited, and would likely be considered Critically Endangered (CR), as we have found only two populations. A key to identify Davilla species known to Goiás State, Brazil, is provided.

Tomato spotted wilt orthotospovirus shifts sex ratio toward males in the western flower thrips, Frankliniella occidentalis, by down-regulating a FSCB-like gene.

Plant viruses can facilitate their transmission by modulating the sex ratios of their insect vectors. Previously, we found that exposure to tomato spotted wilt orthotospovirus (TSWV) in the western flower thrips, Frankliniella occidentalis, led to a male-biased sex ratio in the offspring. TSWV, a generalist pathogen with a broad host range, is transmitted primarily by F. occidentalis in a circulative-propagative manner. Here, we integrated proteomic tools with RNAi to comprehensively investigate the genetic basis underlying the shift in vector sex ratio induced by the virus. Proteomic analysis exhibited 104 differentially expressed proteins between F. occidentalis adult males with and without TSWV. The expression of the fiber sheath CABYR-binding-like (FSCB) protein, namely FoFSCB-like, a sperm-specific protein associated with sperm capacitation and motility, was decreased by 46%. The predicted FoFSCB-like protein includes 10 classic Pro-X-X-Pro motifs and 42 phosphorylation sites, which are key features for sperm capacitation. FoFSCB-like expression was gradually increased during the development and peaked at the pupal stage. After exposure to TSWV, FoFSCB-like expression was substantially down-regulated. Nanoparticle-mediated RNAi substantially suppressed FoFSCB-like expression and led to a significant male bias in the offspring. These combined results suggest that down-regulation of FoFSCB-like in virus-exposed thrips leads to a male-biased sex ratio in the offspring. This study not only advances our understanding of virus-vector interactions, but also identifies a potential target for the genetic management of F. occidentalis, the primary vector of TSWV, by manipulating male fertility. © 2022 Society of Chemical Industry.

Spatiotemporal Delivery of pBMP2 and pVEGF by a Core-Sheath Structured Fiber-Hydrogel Gene-Activated Matrix Loaded with Peptide-Modified Nanoparticles for Critical-Sized Bone Defect Repair.

The clinical translation of bioactive scaffolds for the treatment of large segmental bone defects remains a grand challenge. The gene-activated matrix (GAM) combining gene therapy and tissue engineering scaffold offers a promising strategy for the restoration of structure and function of damaged or dysfunctional tissues. Herein, a gene-activated biomimetic composite scaffold consisting of an electrospun poly(ε-caprolactone) fiber sheath and an alginate hydrogel core which carried plasmid DNA encoding bone morphogenetic protein 2 (pBMP2) and vascular endothelial growth factor (pVEGF), respectively, is developed. A peptide-modified polymeric nanocarrier with low cytotoxicity and high efficiency serves as the nonviral DNA delivery vector. The obtained GAM allows spatiotemporal release of pVEGF and pBMP2 and promotes osteogenic differentiation of preosteoblasts in vitro. In vivo evaluation using a critical-sized segmental femoral defect model in rats shows that the dual gene delivery system can significantly accelerate bone healing by activating angiogenesis and osteogenesis. These findings demonstrate the effectiveness of the developed dual gene-activated core-sheath structured fiber-hydrogel composite scaffold for critical-sized bone defect regeneration and the potential of cell-free scaffold-based gene therapy for tissue engineering.

A Trimode Thermoregulatory Flexible Fibrous Membrane Designed with Hierarchical Core-Sheath Fiber Structure for Wearable Personal Thermal Management.

Advanced textiles designed for personal thermal management contribute to thermoregulation in an individual and energy-saving manner. Textiles incorporated with phase changing materials (PCMs) are capable of bridging the supply and demand for energy by absorbing and releasing latent heat. The integration of solar heating and the Joule heating function supplies multidriving resources, facilitates energy charging and storage, and expands the service time and application scenarios. Herein, we report a fibrous membrane-based textile that was developed by designing the hierarchical core-sheath fiber structure for trimode thermal management. Especially, coaxial electrospinning allows an effective encapsulation of PCMs, with high heat enthalpy density (106.9 J/g), enabling the membrane to buffer drastic temperature changes in the clothing microclimate. The favorable photothermal conversion performance renders the membrane with the high saturated temperature of 70.5 °C (1 sun), benefiting from the synergistic effect of multiple light harvesters. Moreover, a conductive coating endows the composite membrane with an admirable electrothermal conversion performance, reaching a saturated temperature of 73.8 °C (4.2 V). The flexible fibrous membranes with the integrated performance of reversible phase change, multi-source-driven heating, and energy storage present great advantages for all-day, energy-saving, and wearable individual thermal management applications.
