Silane-modified layered double hydroxides with europium sensor for singlet oxygen detection

A silane-modified layered double hydroxide (LDH) hybrid with a covalently coupled europium complex for aqueous singlet oxygen (1O2) detection is presented. A Mg/AL-LDH is modified with two alkoxysilanes simultaneously to increase its covalent linkability (using -SH or -NH2 groups) and to improve its dispersibility in water (using -N+(CH3)3 groups). The europium complex – here acting as the 1O2 probe – is coupled to the –SH or -NH2 - modified LDH employing epoxyphenanthroline (5,6-Epoxy-5,6-dihydro-[1,10]phenanthroline, “ephen”), which is acting as an ancillary ligand to the europium via its hetero-aromatic N-atoms on one hand and allows the covalent linkage of its epoxy-group to the modified LDH on the other hand. In this manner, the silane chains keep the europium complex away from the chemically active LDH surface, hence maintaining its structural integrity and photophysical properties. The result is a water-dispersible probe with a remarkable response to 1O2. This is signaled by the significant increase in the characteristic Eu3+ emission at 613 nm resulting in up to a 27-fold increase in emission intensity on exposure to 1O2 having a decay time of 380 μs. The resulting Eu-LDH hybrid is applicable for heterogeneous aqueous 1O2 detection; its long decay time, useful in time-gated measurements, in conjunction with the biocompatibility of LDH makes it particularly suitable for biological matrices, where 1O2 needs to be monitored.

A strategy for introducing biopotency-enhanced chirality coating on bio-magnesium

Biomedical magnesium alloys (Mg) are often considered potential metallic materials for bone repair scaffolds due to their excellent biomechanical properties, biocompatibility, and biodegradability. However, their rapid degradation behavior is insufficient to support the rapid growth and repair of living tissues. The new surface modification methods to slow down the degradation rate of Mg scaffolds and promote the rapid growth of living tissues is urgent. Here, we developed a chiral-enhanced composite functional coating on the surface of biomedical magnesium. Specifically, a chiral supramolecular hydrogel with graphene oxide (GO) was used to simulate the chiral environment of biological systems, enhancing the adsorption of osteogenic growth factors. Additionally, the silane layers cleverly crosslink traditional silane chains with supramolecular chiral fibers through a hydrogen bond network, which allows the bonding strength (critical loads) of the composite coating to be maintained between 245–275 mN and retains structural integrity when soaked in SBF for 7 days. It was found that both MC3T3-E1 cells growth and BMP-2 adhesion were significantly enhanced by GO-added left-handed chiral coatings, which exhibit superior bone growth-promoting effects. In summary, incorporating chiral features into functional coatings represents a transformative approach in the design and application of bone defect repair materials.

De novo construction of amine-functionalized metal-organic cages as heterogenous catalysts for microflow catalysis

Microflow catalysis is a cutting-edge approach to advancing chemical synthesis and manufacturing, but the challenge lies in developing efficient and stable multiphase catalysts. Here we showcase incorporating amine-containing metal-organic cages into automated microfluidic reactors through covalent bonds, enabling highly continuous flow catalysis. Two Fe4L4 tetrahedral cages bearing four uncoordinated amines were designed and synthesized. Post-synthetic modifications of the amine groups with 3-isocyanatopropyltriethoxysilane, introducing silane chains immobilized on the inner walls of the microfluidic reactor. The immobilized cages prove highly efficient for the reaction of anthranilamide with aldehydes, showing superior reactivity and recyclability relative to free cages. This superiority arises from the large cavity, facilitating substrate accommodation and conversion, a high mass transfer rate and stable covalent bonds between cage and microreactor. This study exemplifies the synergy of cages with microreactor technology, highlighting the benefits of heterogenous cages and the potential for future automated synthesis processes

Preparation and mechanism research on hydrophobic coupling modification of HTV silicone rubber

Neat high-temperature vulcanized silicone rubber (HTV SR) showed bad hydrophobicity due to the existence of a large number of inorganic reinforcing fillers on its surface, which affected its security application in outdoor insulation systems. In this work, hydrophobic silane chains were grafted onto the surface of inorganic particles on the skin layer of HTV SR by a one-step coupling modification to improve its hydrophobicity. The effects of coupling agent types and coupling reaction conditions on the hydrophobicity of HTV SR were investigated. It was determined that the perfluorooctane trichlorosilicon with a large number of low surface energy fluorine atoms was the preferred coupling agent. The contact angle of HTV SR was increased by 15.70% when the optimal coupling reaction conditions were determined to be a reaction temperature of 60°C, a reaction time of 4 h, and an amount of coupling agent of 0.5%. The study found that both etching reaction and grafting reaction occurred during the whole coupling modification process, which led to the disappearance or decrease of a lot of holes on the HTV SR surface. After the fluorination coupling reaction, the surface of HTV SR became smooth and dense that led to the decrease of water absorption. The result of Fourier-transform infrared spectroscopy analysis showed the formation of C-F bond in HTV SR after fluorination modification, and the energetic dispersive spectroscopy analysis showed that the fluorine content on the surface of the fluorinated HTV SR increased significantly. Moreover, the stability analysis showed that the fluorinated HTV SR still had a good thermal stability and mechanical property stability.

Surface activity, foamability, and foam stability of binary mixed systems based on siloxane-based Gemini and hydrocarbon surfactants

Aiming to explore the potential of siloxane-based Gemini surfactants in the development of environmentally friendly foam extinguishing agent to address the pollution caused by traditional fluorinated ones. A crucial step is to study the performance of binary mixed systems of siloxane-based Gemini and hydrocarbon surfactants in terms of surface activity, foamability, and foam stability. In this study, binary mixed systems of two types of siloxane-based Gemini surfactants and one siloxane surfactant with four different hydrocarbon surfactants are prepared. Parameters such as surface tension, foam height, drainage time, and coarsening rate are tested. The results show that the siloxane-based Gemini surfactant HY-4000 with double silane chains could effectively reduce the surface tension of hydrocarbon surfactants. In addition, the two types of Gemini surfactants performed better in enhancing the foamability of hydrocarbon surfactants. The siloxane OFX0193 even inhibits the foaming of cationic hydrocarbon surfactant CATC. Besides the HY-4000/APG0180 mixed system, the binary mixed systems of three silicone surfactants with AOS and APG0180 exhibit better foam stability, particularly the systems containing TEGO4100. For the coarsening process of foam bubbles, we develop a predictive model based on previous studies, where the relationship between bubble area and time follows a power function law. The findings of this study could provide guidance for the development of green foam extinguishing agent with siloxane-based Gemini and hydrocarbon surfactants as core components.

Superior corrosion- and wear-resistance of graphene oxide with the aid of composite silanes

The practical application of magnesium alloy was limited greatly by the inherent poor corrosion- and wear-resistance. Herein, a composite coating composed of graphene oxide (GO), bis[3-(triethoxysilyl)propyl]tetrasulfide and octadecyltrimethoxysilane was prepared by spin-coating. Due to the cross-linking between silanes and GO, the so-obtained composite coating was more compact and less porous as compared with the coating of GO. The hydrophobicity was enhanced by the -S-S-S-S- moiety and high-density CH2 group in the silane chain; consequently, the so-obtained composite coating having the contact angle of about 140° was more hydrophobic as compared with the coating of GO (about 10°). Such a composite coating with higher hydrophobicity, denser siloxane networks and more compacter layered GO could slow down the permeation of corrosion medium and prolong the corrosion path. It was found that, compared to that of the Mg alloy substrate, the Ecorr of the composite coating increased by 713 mV and the icorr value decreased by nearly three orders of magnitude. Moreover, the composite coating possessed excellent wear resistance due to the intrinsic layered structure of GO and the good lubricity of silane.

Moisture resistance improvement of carbonaceous fibers for antistatic coating by modification with long carbon chain silane

Although the general carbon fibers are very stable, low-temperature carbonized carbonaceous fibers were sensitive to moisture, which would lead to unstable electrical conductivity, and seriously endanger the antistatic properties of antistatic coating when carbonaceous fibers were used as conductive filler. In this work, a simple dipping modification is proposed to improve the stability of fiber resistivity by using a long carbon chain silane coupling agent (hexadecyltrimethoxysilane) to perform surface moisture-proof treatment on carbonaceous fibers. The modification was demonstrated to significantly improve the stability of fiber resistivity by accelerated experiments in hygrothermal and salt spray environments. After 72 h treatment in hygrothermal environment, the increase percentage of untreated carbonaceous fiber resistivity reached 70%. Nevertheless, that of CF@KH1631-6 was 40%. Good hydrophobicity was achieved at a concentration of 6 wt%, water contact angle increasing from 135.6° to 152.2°. Furthermore, the whole preparation process had the potential of large-scale industrial production and application.

Silane or Siloxane‐Side‐Chain Engineering of Photovoltaic Materials for Organic Solar Cells†

Comprehensive SummaryWith the tactful material design, skillful device engineering, and in‐depth understanding of morphology optimization, organic solar cells (OSCs) have achieved considerable success. Therefore, OSCs have reached high power conversion efficiencies (PCEs) exceeding 19%. Especially, continuously emerging new materials have been considered as one of the key factors to improve the PCEs of OSCs. Among molecular design strategies, side‐chain engineering is an easy and commonly‐used means which can optimize the solubility, alter intermolecular stacking arrangement, fine‐tune the open circuit voltage (VOC), thus ultimately improve the performance. As hybrid side chains, silane and siloxane side chains have considerable effects, not only in increasing the carrier mobility and tuning the energy level, but also in affecting the crystallinity and molecular orientation. In this review, the latest developments in photovoltaic materials based on silane and siloxane side chains are presented to illustrate the structure‐property relationships. The review comprehensively includes silane‐side based polymer/small molecule donors; siloxane‐side based polymer/small molecule donors, and polymer/small molecule acceptors. Then the similarities and differences between these two side chains are demonstrated. Finally, the possible applications and future prospects of silane and siloxane side chains are presented.

"Rigid-Flexible" Anisotropic Biomass-Derived Aerogels with Superior Mechanical Properties for Oil Recovery and Thermal Insulation.

Aerogels with low density, high mechanical strength, and excellent elasticity have a wide potential for applications in wastewater treatment, thermal management, and sensors. However, the fabrication of such aerogels from biomass materials required complex preparation processes. Herein, a sustainable and facile strategy was reported to construct lignin/cellulose aerogels (LCMA) with three-dimensional interconnected structures by introducing homologous lignin with a polyphenyl propane structure as a structural enhancer through a top-down directional freezing approach, prompting a 2036% enhancement in compressive modulus and an 8-12-fold increase in oil absorption capacity. In addition, the hydrophobic aerogels with superelasticity were achieved by combining the aligned polygon-like structure and flexible silane chains, which exhibited remarkable compressional fatigue resistance and superhydrophobicity (WCA = 168°). Attributed to its unique pore design and surface morphology control, the prepared aerogel exhibited excellent performance in immiscible oil-water separation and water-in-oil emulsion separation. Due to the ultra-low density (8.3 mg·cm-3) as well as high porosity (98.87%), the obtained aerogel showed a low thermal conductivity (0.02565 ± 0.0024 W·m-1·K-1), demonstrating a potential in insulation applications. The synthetic strategy and sustainability concept presented in this work could provide guidance for the preparation of advanced biomass-based aerogels with unique properties for a wide range of applications.

Aminosilane Functionalized Aligned Fiber PCL Scaffolds for Peripheral Nerve Repair.

Silane modification is a simple and cost-effective tool to modify existing biomaterials for tissue engineering applications. Aminosilane layer deposition has previously been shown to control NG108-15 neuronal cell and primary Schwann cell adhesion and differentiation by controlling deposition of ─NH2 groups at the submicron scale across the entirety of a surface by varying silane chain length. This is the first study toreport depositing 11-aminoundecyltriethoxysilane (CL11) onto aligned Polycaprolactone (PCL) scaffolds for peripheral nerve regeneration. Fibers are manufactured via electrospinning and characterized using water contact angle measurements, atomic force microscopy (AFM), and X-ray photoelectron spectroscopy (XPS). Confirmed modified fibers are investigated using in vitro cell culture of NG108-15 neuronal cells and primary Schwann cells to determine cell viability, cell differentiation, and phenotype. CL11-modified fibers significantly support NG108-15 neuronal cell and Schwann cell viability. NG108-15 neuronal cell differentiation maintains Schwann cell phenotype compared to unmodified PCL fiber scaffolds. 3D ex vivo culture of Dorsal root ganglion explants (DRGs) confirms further Schwann cell migration and longer neurite outgrowth from DRG explants cultured on CL11 fiber scaffolds compared to unmodified scaffolds. Thus, a reproducible and cost-effective tool is reported to modify biomaterials with functional amine groups that can significantly improve nerve guidance devices and enhance nerve regeneration.

Nanochannel-Induced Efficient Water Splitting at the Superhydrophobic Interface.

Constructing a favorable reaction configuration at the water/catalyst interface is crucial for high-efficiency semiconductor-based water splitting. For a long time, a hydrophilic surface of semiconductor catalysts has been considered necessary for efficient mass transfer and adequate contact with water. In this work, by constructing a superhydrophobic PDMS-Ti3+/TiO2 interface (denoted P-TTO) with nanochannels arranged by nonpolar silane chains, we observe overall water splitting efficiencies improved by an order of magnitude under both the white light and simulated AM1.5G solar irradiation compared to the hydrophilic Ti3+/TiO2 interface. The electrochemical overall water splitting potential on the P-TTO electrode also decreased from 1.62 to 1.27 V, which is close to the thermodynamic limit of 1.23 V. Through the in situ diffuse reflection infrared Fourier transform spectroscopy, a nanochannel-induced water configuration transition is directly detected. The density functional theory calculation further verifies the lower reaction energy of water decomposition at the water/PDMS-TiO2 interface. Our work achieves efficient overall water splitting through nanochannel-induced water configurations without changing the bulk of semiconductor catalyst, which reveals the significant role of water status at the interface in the efficiency of the water splitting reaction over the properties of catalyst materials.

Nanotribological interactions at the interface between polydimethylsiloxane and silane-modified silica

This research was conducted to show that long alkyl chains of silane, grafted on the surface of silica, can interact with liquid polydimethysiloxane (PDMS) matrix through a so called nanotribological interaction at the interface. Some nonlinear behavior was reported as the result of this interaction. For this purpose, composites of PDMS and silica modified by silanes with two different alkyl chain lengths of three (short) and sixteen (long) carbons were prepared. Also, small molecule silicone oil was utilized as the matrix to be compared with the rubber matrix in this type of interaction. Initially, the surface energy of modified silicas as an enthalpic driving force for polymer-filler and filler-filler interactions were made almost equal in order to reveal features of nanotribological interactions resulting from long alkyl chains of silane. Microscopic results indicated that long alkyl chains of silane are effective in better dispersion of silica particles in the rubber matrix. Also, the strain-sweep rheological behavior of the composites showed that at concentrations below the percolation threshold of silica, the long alkyl chains of silane can tribologically engage with the rubber matrix, resulting in an instability in storage modulus, even with better dispersion of particles. This observation was attributed to some engagement-disengagement of polymer at the interface rather than networking of particles, known as the Payne effect. However, silica grafted by the short chain silane did not show this behavior. This type of interaction was showed to be also effective in filler-filler interactions and networking for silica grafted with long chain silane, high above the percolation threshold of silica in PDMS. It was shown that this type of interaction is absent in silicone oil, revealing the essential role of molecular weight of matrix in nanotribological interactions with the long alkyl chains of silane.

Preparation and properties of nano-MgO/HDTMS super hydrophobic multifunctional cotton

First, nano-sized magnesium oxide (MgO) particles were prepared with magnesium nitrate hexahydrate as raw material and plant extract Angelica dahurica as a protective agent and dispersant. Then, MgO nano particles (MgO NPs) were loaded on the cotton fabric surface by dipping method. Finally, using hexadecyl trimethoxysilane (HDTMS) as a modifier and ammonia as a catalyst, the cotton fabric was hydrophobically modified to prepare a super hydrophobic multifunctional cotton fabric. FTIR indicated that long carbon chain silane was successfully introduced onto cotton fabric. SEM and XRD analysis showed that the micro-nano rough structure was formed on the MgO/HDTMS/cotton fabric surface, and its crystal structure was unchanged. The water contact angle of cotton fabric modified by MgO/HDTMS reached 153°, which made it super hydrophobic. Moreover, MgO/HDTMS/cotton fabric has excellent antibacterial properties with the antibacterial rates against S. aureus and E. coli of 95.50% and 95.30%, respectively. After 10 times of cyclic washing, both the water contact angle and the antibacterial rate for S. aureus and E. coli of the fabric showed a slight decrease, which indicated that it has good washing durability.

Surface polarity tuning through epitaxial growth on polyvinylidene fluoride membranes for enhanced performance of liquid-solid triboelectric nanogenerator

Although liquid-solid triboelectric nanogenerator (LS-TENG) has been taken into consideration as a remarkable promising renewable clean energy source for electronic devices, their performances are still limited to be practically utilized owing to the weak polarity and inadequate functional groups of triboelectric materials. In this work, we propose a high-performance LS-TENG reached from surface polarity tuning through epitaxial growth on polyvinylidene fluoride (PVDF) membrane. The PVDF surface functional is treated with silica nanoparticles (SiNPs) through chemical bonding and then grafted with negatively charged 1H,1H,2H,2H-Perfluorooctyltriethoxysilane (FOTS) to forming the FOTS/SiNPs/PVDF (FSiP) membrane. The proposed membrane can induce fluorine-bearing silane chains and increase the interfacial polarization, leading to the outstanding hydrophobic property and dielectric constant. In consequence, the output power of FSiP-TENG demonstrates superior triboelectric performance with a current of 5.79 μA, a voltage of 28.3 V, and the highest power density of 420 mW/m2, a 10.8 times improvement compared to the PVDF-TENG. Considering the excellent durability, stability, and water-resistant, the FSiP-TENG can develop into a water energy harvesting device and a liquid self-powered sensor to be used in our daily life.

Study on the adsorption process of Cd(II) by Mn-diatomite modified adsorbent

Using adsorbents to remove cadmium, a highly toxic element, from the aqueous solution is an effective method. Cd (II) adsorbent was prepared from modified diatomite, using NaOH and MnCl2 as compound modifiers. The microstructure of the samples was studied by SEM, IR, and XRD. And the adsorbent modification and the adsorption process of Cd (II) were analyzed. The results showed that the active silane chain on the diatomite matrix surface was opened during the modification process. And then the manganese modified material was grafted on the active hydroxyl site and the opened silane chain respectively. And some Mn4+ substituted Al3+ were grafted on the surface of the diatomite. Compared with diatomites, the specific surface area of the adsorbent grafted with manganese oxide was increased by about 8 times, and a large number of manganese hydroxyl sites were formed on its surface. Thus, compared with the unmodified diatomite, the adsorption rate of Cd (II) on the modified adsorbent was increased to 98.69%, suggest that modified diatomite could be employed as an efficient adsorbent for the removal of Cd(II) from wastwater.

Effect of PCEs with different structures on hydration and properties of cementitious materials with low water-to-binder ratio

Polycarboxylate ethers (PCEs) with different structures and densities of anchor groups in the backbone were synthesized and characterized. The surface tension of their solutions, their adsorption on cementitious particles and zeta potential of cement-silica fume pastes with PCEs were measured. Their effects on hydration and properties of cement-silica fume paste with low water-to-binder ratio were examined. Results indicated that the adsorption kinetics of theses PCEs on cementitious particles are fitted the pseudo-second-order model. The introduction of long silane chain on PCE decreased its electrostatic adsorption, while PCE was adsorbed onto the surface of particles via both chemical and electrostatic adsorption, when silicon hydroxyl is directly connected to its backbone. In the presence of PCE with higher adsorbed amount, pastes exhibited lower yield stress and higher flowability, and higher strength at 7 d and 28 d. The low plastic viscosity, autogenous and drying shrinkage were related to the low surface tension of PCE solution.

Shaping and silane coating of a diamine-grafted metal-organic framework for improved CO2 capture

Although metal-organic framework (MOF) powders can be successfully shaped by conventional methods, postsynthetic functionalization of the shaped MOFs remains almost unexplored, yet is required to overcome intrinsic limitations, such as CO2 adsorption capacity and stability. Here, we present a scalable synthesis method for Mg2(dobpdc) MOF and its shaped beads, which are obtained by using a spray dry method after mixing Mg2(dobpdc) powders with alumina sol. The synthesized MOF/Al beads have micron-sized diameters with a moderate particle size distribution of 30–70 μm. They also maintain a high mechanical strength. N-ethylethylenediamine (een) functionalization and coating with long alkyl chain silanes results in een-MOF/Al-Si, which exhibits a significant working capacity of >11 wt% CO2 capture and high hydrophobicity. The een-MOF/Al-Si microbeads retain their crystallinity and improved CO2 uptake upon exposure to humid conditions for three days at a desorption temperature of 140 °C.

Surface Energy Characterized Self-Assembled Monolayer for Improving Electrical Stability of IGZO Thin Film Transistor

The surface energy characterized self-assembled monolayer (SAM) for improving the electrical stability of Indium gallium zinc oxide (IGZO) semiconductor is proposed. In order to compare properly, the head group and body group were fixed with silane and alkyl chains, respectively, and only the functional group was changed, NH2, CH3, CF3 respectively. The surface energies of NH2, CH3 and CF3 functional group SAMs were measured as 50 mJ/m2, 29 mJ/m2 and 24 mJ/m2, respectively by Owens-Wendt model with the contact angle values. The SAM treatment for IGZO TFT backchannel passivation amazingly improves the positive bias stability (PBS) and clockwise hysteresis stability to the very similar tendency by making oxygen-related molecules difficult to be adsorbed onto IGZO backchannel depending on the surface energies of SAMs. In case of NH2 SAM treated IGZO TFT, the PBS improvement ratio by the treatment was 78.7 % (from 11.6 V to 2.5 V) and the clockwise hysteresis improvement ratio was 70.5 % (from 0.8 V to 0.2 V). Furthermore, it was confirmed that the better result was obtained at a lower surface energy functional group. The IGZO TFT PBS further improved 87.0 % after the lowest surface energy with CF3 SAM treatment (from 2.5 V to 0.3 V), and the IGZO TFT clockwise hysteresis was also further enhanced 52.2 % (from 0.2 V to 0.1 V) without any deterioration of TFT characteristics. The field-effect mobility and sub-threshold swing of the IGZO reference TFT with non-SAM treated were 11.2 cm2 / Vs and 0.2 V / decade, respectively. NH2, CH3, and CF3 functional group SAM treated IGZO TFTs show the field-effect mobility of 13.5 cm2 / Vs, 13.0 cm2 / Vs, 13.1 cm2 / Vs, and sub-threshold swing of 0.18 V / decade, 0.20 V / decade, 0.18 V / decade, respectively. As a result, the simple and economical SAM treatment with lower surface energy functional group surface at same head and body group can be a better way in passivating and protecting the IGZO backchannel region from oxygen molecules in the atmosphere in order to enhance the electrical stability of IGZO TFT.

Enhanced performance of a cellulose nanofibrils-based triboelectric nanogenerator by tuning the surface polarizability and hydrophobicity

Cellulose is the most abundant natural polymer on earth. Because it is renewable, biodegradable, and biocompatible, it offers distinct advantages as a starting material for bio-based triboelectric nanogenerator (bio-TENG). However, weak polarity, poor hydrophobicity, and insufficient functionalization on the natural cellulose surface severely limit the development of high-performance cellulose-based TENGs. In this work, chemical functionalization is employed to control the surface polarizability and hydrophobicity of cellulose nanofibrils (CNFs). Functional groups on the CNF surface are modified with triethoxy-1H,1H,2H,2H-tridecafluoro-n-octylsilane (PFOTES) in a straightforward and facile process. Fluorine-bearing silane chains are grafted to the surface of CNFs, which increases their triboelectric charge density and improves their hydrophobicity. Experimental results demonstrate that the surface polarity of CNFs is greatly improved after PFOTES modification. The PFOTES-CNF-based TENG exhibits good resistance to humidity and long-term cycle stability, and it retains 70% of the initial output performance at 70% ambient humidity. The short-circuit current of the PFOTES-CNF-based TENG reached 9.3 μA, which is about twice that of CNF-based TENG prior to modification. These results clearly indicate that PFOTES can be used to control CNF surface polarizability and hydrophobicity, advancing the search for durable, high-performance, degradable bio-TENGs.

Effect of injection molding on structure and properties of poly(styrene‐ethylene‐butylene‐styrene) and its nanocomposite with functionalized montmorillonite

AbstractIn this paper, the effects of injection molding on structure and properties of poly(styrene‐ethylene‐butylene‐styrene) (SEBS) and its nanocomposite with a functionalized montmorillonite (FMMT) were illustrated by comparison with the results of hot pressing. The injection‐molded SEBS and its FMMT nanocomposite have a skin‐core morphology with FMMT platelets more preferentially aligned along the sample plane, while hot‐pressed samples not. The injection‐molded samples also have a dense structure, and a less extent of microphase separation. In the injection molding process, the high shear flow coupled with solidification in presence of temperature gradient and high pressure in the closed cavity greatly affect the morphology and structure of the SEBS and its nanocomposites. The results also indicate attractive interaction between the soft segments of SEBS and the long alkyl silane chain grafted to FMMT, which allows FMMT to form a macroscopic network structure after the high‐speed and high‐pressure injection molding. The SEBS/FMMT‐injected nanocomposite have the highest tensile strength and the best corrosion resistance, which can be attributed to the dense skin‐core structure, stronger SEBS/FMMT interaction and the preferentially aligned FMMT platelets.
