Ultrathin Serpentine Insulation Layer Architecture for Ultralow Power Gas Sensor.

Toxic gases have surreptitiously influenced the health and environment of contemporary society with their odorless/colorless characteristics. As a result, a pressing need for reliable and portable gas-sensing devices has continuously increased. However, with their negligence to efficiently microstructure their bulky supportive layer on which the sensing and heating materials are located, previous semiconductor metal-oxide gas sensors have been unable to fully enhance their power efficiency, a critical factor in power-stringent portable devices. Herein, an ultrathin insulation layer with a unique serpentine architecture is proposed for the development of a power-efficient gas sensor, consuming only 2.3mW with an operating temperature of 300 °C (≈6% of the leading commercial product). Utilizing a mechanically robust serpentine design, this work presents a fully suspended standalone device with a supportive layer thickness of only ≈50nm. The developed gas sensor shows excellent mechanical durability, operating over 10 000 on/off cycles and ≈2 years of life expectancy under continuous operation. The gas sensor detected carbon monoxide concentrations from 30 to 1ppm with an average response time of ≈15 s and distinguishable sensitivity to 1ppm (ΔR/R0 = 5%). The mass-producible fabrication and heating efficiency presented here provide an exemplary platform for diverse power-efficient-related devices.

(Invited) Textile Composite Electrodes for Wearable Batteries and Beyond

Wearable energy storage devices are indispensable corner stones for future wearable electronics. Current energy storage technologies are based on materials and devices that are rigid, bulky, and heavy, making them difficult to wear. On the other hand, fibers are flexible and lightweight materials that can be assembled into different textiles and have been worn by human beings thousands of years. Different from conventional two-dimensional thin films and foils, the three-dimensional fibre and textile structures not only provide superior wearing ability, but also much larger surface areas. This talk will introduce how our research group makes use of the attributes of fibres for high-performance wearable energy storage devices. We will demonstrate the strategies and discuss the perspectives to modify fibers and textiles for making wearable capacitators and batteries with excellent mechanical durability, electrochemical stability, and high energy/power density. We will also show that the fibrous materials can significantly enhance the stability and energy density of battery for wearable applications and others such as Na battery.

Effect of modified nano-SiO2 on properties and microstructure of the high-performance cementitious composites

The effect of modified nano-SiO2 (MNS) on the performance of high-performance cementitious composites (HPCC) was investigated and the underlying mechanism was revealed by various microscopic analysis and testing methods. Results indicated that the fluidity of HPCC initially increased and then decreased with the increase of MNS content. Meanwhile, The HPCC with 0.8% MNS exhibited a 25% increase in compressive strength at the curing age of 3 days, while the HPCC with 0.8% nano-SiO2 showed a 10% increase. Compared with the reference mixture, the durability and autogenous shrinkage of HPCC with MNS were significantly improved, the chloride diffusion coefficient of HPCC with 0.8% MNS decreased by 25.9%. Furthermore, the quantitative analysis results of hydration process and hydration products show that the inclusion of nano-materials accelerated the hydration rate of cementitious composites, resulting in increased cumulative heat release. HPCC with MNS exhibited a higher generation of amorphous phases and greater consumption of calcium hydroxide compared with reference mixture. Moreover, the addition of MNS effectively refined the pore size of HPCC and converted some harmful pores into less harmful or harmless pores, enhancing the microstructure of HPCC with MNS and improving the interface transition zone. This optimization was mainly attributed to the effect of filling, nucleation of crystal and pozzolanic reactive of nano-materials, which further benefit from the good dispersion of MNS, resulting in excellent mechanical properties and durability of HPCC.

Construction of a durable superhydrophobic flame-retardant coating on the PET fabrics

In order to meet the increasing demand for fire prevention and pollution prevention of polyester fiber fabrics (PET) in different scenes, it is imperative to develop surface coatings with superhydrophobic and flame retardant properties. However, how to realize all these functions at the same time is still a big challenge. In this work, fluorinated PDMS was obtained through the cross-linking reaction between fluorosilane and PDMS, which was evenly mixed with the combustion product of silicone rubber (mainly composed of SiO2) and ammonium polyphosphate (APP), and the mixed coating was deposited on the surface of PET fabrics by spraying method to construct a superhydrophobic flame-retardant coating. The coated fabrics shows good superhydrophobicity (water contact angle is 155.61 ± 1.42°, sliding angle is 3.2 ± 0.4°) and self-cleaning performance. In particular, the prepared coated fabrics also has excellent mechanical durability, and it still does not lose its superhydrophobicity after 10 abrasive paper rubbing cycles, 60 min washing and even 300 bending and twisting cycles. In addition, compared with the original fabrics, the coating shows excellent flame retardant performance, which can realize self-extinguishing within 10 s in vertical combustion experiment.

A smart electroplating approach to fabricate mechanically robust and fluorine-free Ni-W alloys based superhydrophobic coating on Al alloy

In this study, a novel and smart electroplating method was presented to fabricate a mechanically robust superhydrophobic coating on Al alloys. The superhydrophobic coating was composed of Ni-W alloy film with high hardness and stearic acid (STA) with low surface energy, providing excellent abrasive resistance, anti-corrosion properties, and self-cleaning ability. Specifically, a thin transition layer of Al-Ni-W was pre-electroplated on the Al alloy substrate by utilizing Al as anode and Al alloys as cathode in Ni-W ions aqueous solution, which overcome the difficulty of directly electroplating alloys coating on the Al alloys surface. Finally, a robust composite superhydrophobic film was achieved after coating STA layer on Al alloy/Al-Ni-W/Ni-W substrate. As anticipated, the as-prepared Al alloys demonstrates excellent mechanical durability and chemical stability, including wear resistance, hardness, corrosion resistance and self-cleaning with a champion water contact angle of 163° and corrosion protection efficiency of 99.4%. The Leeb hardness of superhydrophobic film coated Al alloys was enhanced by 87.1% compared to the pristine Al alloys, increasing from 325 ± 3 to 608 ± 4. This method provides a universal pathway for fabricating robust superhydrophobic film on the active metallic substrates.

Robust and durable self-lubricated surface by facile fabrication for anti-icing/deicing

Undesired ice accumulation can lead to serious negative impacts on daily life and equipment safety. Slippery liquid-infused surfaces (SLISs) have been widely studied for their low ice adhesion strength (τice). However, the lack of durability, weak robustness, and complex preparation process hinder the application of SLISs. In this work, robust oil-infused porous surface (RIPS) was obtained by a facile one-step method, which used epoxy resin (E44) as a substrate and contained fumed silica and silicone oil. The RIPS-6 displays outstanding anti-icing/deicing ability, superior liquid repellency, good self-cleaning performance, and excellent mechanical robustness. At −5 °C, the water droplet remained unfrozen after 7200 s. τice was only 6.9 kPa at −20 °C and remained below 15 kPa during 10 icing cycles. Furthermore, the mixture of E44 and fumed silica enhanced the mechanical properties including the hardness (4 H) and abrasion resistance of RIPS-6. The icephobicity can be remained (τice < 40 kPa) even after 150 cycles of sandpaper abrasion at 2.5 kPa. The anti-icing and deicing coating with excellent mechanical stability and durability significantly improves the practical application possibility of the coating in harsh environments.

Enhancing the Electrical Conductivity and Strength of PET by Single-Wall Carbon Nanotube Film Coating.

Single-wall carbon nanotubes (SWCNTs) with excellent physicochemical properties are considered a promising candidate for the electrical and mechanical reinforcements of polymers. However, the poor dispersion of SWCNTs in plastics seriously limits their application and their achieved performance enhancement. Here, we coat a freestanding, highly conductive SWCNT film onto the surface of a polyethylene terephthalate (PET) film by a hot-pressing method. Due to the uniform SWCNT network structure and strong interfacial interaction, the SWCNT/PET hybrid film showed notably enhanced electrical and mechanical properties even though with a very low SWCNT weight fraction of 0.066%. The surface square resistance of the SWCNT/PET film decreased to 120-140 Ω/□ from 1016 Ω. In addition, Young's modulus and tensile strength of the SWCNT/PET film reached 4.6 GPa and 148 MPa, which are 31.3 and 24.4%, respectively, higher than the pure PET film. The SWCNT/PET film shows excellent mechanical durability and thermal stability, demonstrating its potential use as an antistatic material.

Facile fabricant of slippery lubricant-infused porous foam-like surface for efficient fog harvesting

Inspired by pitcher plant, a variety of lubricant-infused surfaces have been created with unique properties. Owing to its high heat transfer performance and negligible contact angle hysteresis, the lubricant-infused surfaces are employed in fog harvesting. However, the loss of lubricant oil can result in performance degradation. Therefore, many surfaces with fine micro/nano structure have been created to increase the lubricant retention ability of lubricant-infused surface. Unfortunately, the procedures for preparing these surfaces are difficult or time-consuming. In this study, we synthesized a porous foam-like lubricant-infused surface (F-LIS). Porous copper foam was created on the surface of copper sheets through the dynamic bubble template method, and the pore walls were made of closely interlaced needle-like nano-dendrites. The fog harvesting efficiency of the surface can reach 2761.2 mgcm−2h−1. Additionally, F-LIS demonstrates excellent mechanical durability and chemical stability as a result of the micro/nano structure and the strong intermolecular force between PFPE as lubricant and the modifier layer, PFDT. After high-speed rotation, prolonged placement and UV irradiation etc., the surface still exhibits brilliant sliding ability and fog harvesting efficiency. This work offers a simple and effective approach for fabricating lubricant-infused surfaces with distinguished fog harvesting capability, providing a reference for relieving the crisis of freshwater resource scarcity.

Femtosecond Laser Preparation of Terracotta Warrior-like Pit Superhydrophobic Structure on Magnesium Alloy with Mechanical Durability and Corrosion Resistance.

Magnesium alloys are among the most promising materials for medical implants, and by preparing a superhydrophobic surface, the rate of corrosion can be effectively slowed down and durability be improved. However, the anticorrosion surfaces are inevitable to be damaged for the conventional micro-nanostructured superhydrophobic magnesium alloys, which highly limits their application prospects. This work proposes the development of a Terracotta Warrior pit superhydrophobic structure (TWPSS), consisting of a wall structure with a Terracotta Warrior-like pit and a lotus-like surface papillae structure within the wall. For the first time, top-down laser ablation of the pits to prepare the lotus-like surface papilla structure is used in conjunction with a bottom-up laser-guided melt stacking of the raised wall structure to achieve rapid fabrication of a TWPSS on a magnesium alloy surface. The Cassie-Baxter-based design of the wall structure spacing effectively protects the internal lotus-like surface papillae from damage and the disappearance of low surface energy material, and the results show that the superhydrophobic surfaces of magnesium alloys have excellent mechanical durability and repairability. In addition, it was found that the recast layer and laser melting stacked layers produced on the surface of the alloy during femtosecond laser processing refined the grain size of the magnesium alloy and effectively suppressed the corrosion rate. The combination of the superhydrophobic gas layer and the resulting grain refinement slowed down the corrosion of the magnesium alloy. Thus, the rapid preparation of TWPSS structures with mechanical durability and corrosion resistance by femtosecond lasers expands the clinical applications of superhydrophobic surface magnesium alloys in medical devices.

Highly Stretchable Strain Sensor with a High and Broad Sensitivity Composed of Carbon Nanotube and Ecoflex Composite

Wearable strain sensors with high and broad sensitivity, high stretchability and excellent mechanical endurance will be widely useful in smart wearable electronics. In this work, we developed a stretchable strain sensor fabricated with a simple stencil printing technique. The stretchable strain sensor was fabricated using a multi-walled carbon nanotubes (MWCNTs)-Ecoflex composite paste on an Ecoflex substrate. In particular, using IPA solvent, CNT particles were uniformly dispersed in the Ecoflex binder. The effect of the amount of Ecoflex resin on the stretchability and sensitivity of the sensor were also investigated. It was found that as the amount of Ecoflex resin increased, the stretchability of the sensor increased. The fabricated stretchable strain sensor showed a maximum stretchability of 1,000% with a wide sensitivity range from 3 to 12,287. The hysteresis tests indicated that the hysteresis of the fabricated stretchable strain sensor was very small, the electrical resistances of the sensors quickly returned to original value after tests. The strain sensor showed excellent mechanical durability during cyclic repeated tensile tests of 400,000 cycles. The results of the cross-cut adhesion tests indicated that the adhesion strength between the sensor composite layer and Ecoflex substrate was excellent. We also demonstrated the potential application of the stretchable sensor in wearable electronics by bending tests on a human finger and wrist.

A Strongly Coupled Ag(S)@NiO/Nickel Foam Electrode Induced by Laser Direct Writing for Hydrogen Evolution at Ultrahigh Current Densities with Long-Term Durability.

Highly active, durable, and cost-effective electrodes for hydrogen evolution reaction (HER) at ultrahigh current densities (≥1 A cm-2 ) are extremely demanded for industrial high-rate hydrogen production, but challenging. Here, a robust strongly coupled Ag(S)@NiO/nickel foam (NF) electrode is reported. Taking advantage of millisecond laser direct writing in liquid nitrogen technique, lattice-matched and coherent interfaces are formed between Ag nanoparticles with stacking faults (denoted by Ag(S)) and NiO nanosheets, leading to strong interfacial electronic coupling, not only promoting H2 O adsorption and dissociation on Ni2+ but also enhancing H* adsorption on intrinsically inactive but most electrically conductive Ag. Strong chemical bonding is established at NiO/NF interface, guaranteeing rapid electron transfer and excellent mechanical durability under high-rate hydrogen evolution. The physicochemically stable electrode achieves record-low alkaline HER overpotential of 167 and 180mV at 1 and 1.5 A cm-2 , respectively, along with negligible activity decay after 120h test at ≈1.5 A cm-2 , surpassing reported non-platinum group metal electrocatalysts.

Nontoxic Cross-Linked Graphitic Carbon Nitride-Alginate-Based Biodegradable Transparent Films for UV and High-Energy Blue Light Shielding.

Flexible, transparent, and biodegradable films that can shield dangerous UV and high-energy blue light (HEBL) are high in demand to satisfy the ever-increasing expectations for environmental sustainability. To achieve this goal, biopolymer alginate is an excellent choice that has an outstanding film-forming ability. However, alginate has the limitation of poor UV and HEBL blocking ability. Thus, in this study, UV and HEBL blocker graphitic carbon nitride (g-C3N4) was incorporated in alginate films to enhance the compatibility, applicability, and durability. The ATR-FTIR, TGA, DTG, and FE-SEM results indicated that the composite film formation was due to hydrogen bonding, and the composite films revealed synergistic properties of alginate and g-C3N4. Though the incorporation of g-C3N4 in films enhanced the mechanical and thermal stabilities of the films, the films were still flexible. The UV-visible transmittance characterization confirmed that the prepared films could block both UV and HEBL radiation while maintaining transparency in visible regions. In experiments involving only 2 wt % g-C3N4, nearly 90% of UV (200-400 nm) and 95% of HEBL (400-450 nm) irradiation were blocked. Additionally, the inclusion of g-C3N4 also facilitated the biodegradation process of composite films. Moreover, after 6 months, the composite films exhibited excellent UV and HEBL shielding with excellent mechanical durability.

Scalable Quasi-Solid-State Supercapacitor for Wide-Temperature Wearable Devices.

Quasi-solid-state supercapacitors have wide application prospects in flexible and scalable electronics, which require high capacity, simple form factor, and excellent mechanical robustness. However, it is a challenge to have all these benefits in one material. Addressing this, we report a composite hydrogel with excellent mechanical durability and freezing resistance. The designed composite hydrogel acts both as a load-bearing layer to maintain its structure during deformation and as a permeable binder to stimulate the interfacing between the conductive electrode and the electrolyte to reduce the interface resistance. Flexible supercapacitors are assembled with composite hydrogels and high-performance MnO2/carbon cloth, which has excellent performance and can store energy at different temperatures or bending states. These results show that the tough hydrogel facilitates the improvement of electrical and mechanical stability, showing great potential in wide-temperature wearable devices.

Synthesis of superhydrophobic FAS-EP/PTFE coating with excellent drag reduction performance and mechanical robustness

Superhydrophobic (SHP) materials have great potential for applications in self-cleaning, anti-fouling, anti-corrosion and drag reduction, but their poor mechanical robustness is a fundamental problem that hinders their practical application. In this work, we successfully and rapidly prepared SHP coating with good durability and drag reduction properties by a simple drop-coating technique after chemical modification and physical mixing. We investigated the effects of modification with 1H,1H,2H,2H-Perfluorodecyltriethoxysilane (FAS-17), a low surface free energy material, and the filling content of Poly tetra fluoroethylene (PTFE) on the hydrophobic property of the as-prepared coating. The maximum water contact angle (WCA) and the minimum sliding angle (SA) of the coating were 160.2 ± 0.4° and 5°, respectively. The coating maintained superhydrophobicity after 4.4 m of abrasion with 400 grit sandpaper and 3 h of water impact, indicating its excellent mechanical durability. In addition, it has outstanding self-cleaning and self-repairing properties. Moreover, the coating was innovatively applied to the surface of the chute, because it remarkably reduced the adhesion between the wet foam block and the chute. These findings here provide a novel insight into the design of a robust SHP coating and suggest a new potential application in express sorting industry for drag reduction.

Multifunctional antifouling coatings involving mesoporous nanosilica and essential oil with superhydrophobic, antibacterial, and bacterial antiadhesion characteristics

Bacterial adhesion to material surfaces is a prominent cause of bacterial infections and diseases. Antifouling coatings have garnered increasing attention in recent years as a means to address this significant challenge in surface hygiene and microbiological safety. In this study, a multifunctional antibacterial coating that employs a simultaneous release-inactivation and superhydrophobic antiadhesion strategy is presented. In this context, mesoporous silica nanoparticles were synthesized and chemically modified to provide dual functionality. First, the deposition of nanoparticles establishes a nanotopography with a low surface energy, resulting in a superhydrophobic surface, which minimizes the contact between aqueous bacterial suspensions and the surfaces. Second, periodic nanopores within the nanoparticles could be infused with cinnamon essential oil, which gradually diffuses into the surrounding medium, leading to the inactivation of planktonic bacteria. Quantitatively, the developed coating exhibited notable antibacterial and antiadhesion properties, reducing the proliferation of Gram-negative E. coli and Gram-positive S. aureus by 99.9% and 99.6%, respectively. It also demonstrated excellent mechanical and chemical durability. With its facile, low-cost, and universal fabrication, as well as its metal-free and fluorine-free properties, we anticipate this coating to have significant potential in mitigating the risk of bacterial contamination in biomedical applications and the food industry.

Dual-interface engineering induced by silane coupling agents with different functional groups constructing high-performance flexible perovskite solar cells

Defect-induced charge non-radiative recombination loss at perovskite/charge transport layers (CTLs) interfaces greatly deteriorates the efficiency and stability of flexible perovskite solar cells (PSCs). Therefore, a comprehensive strategy for reducing the defect density both at perovskite/CTLs interfaces is urgently required. Herein, the 1-[3-(Trimethoxysilyl)propyl]urea (TMPU) material is adopted to improve the conductivity of SnO2 and passivate the unfavorable SnO2/perovskite interface defects. Meanwhile, the trimethoxy(3,3,3-trifluoropropyl)silane (TMFS) layer is employed at perovskite/spiro-OMeTAD interface for the sake of suppressing the surface defects of perovskite and ameliorating environmental stability of the perovskite. Such a dual-interface engineering strategy is beneficial to significantly reduce interface defect density and unfavorable non-radiative recombination loss, thus achieving faster transport and effective collection of carriers. Consequently, the optimized flexible and rigid PSCs yield outstanding photoelectric conversion efficiency (PCE) of 20.06% and 23.11%, respectively, which are both significantly higher than the pristine devices. Notably, the target flexible device presents excellent mechanical durability and retains 91.3% of the initial PCE after 5000 bending cycles with bending radius of 10 mm.

Highly robust zinc metal anode directed by organic–inorganic synergistic interfaces for wearable aqueous zinc battery

AbstractFlexible aqueous zinc batteries (FAZBs) with high safety and environmental friendliness are promising smart power sources for smart wearable electronics. However, the bare zinc anode usually suffers from damnable dendrite growth and rampant side reaction on the surface, greatly impeding practical applications in FAZBs. Herein, a composite polymer interface layer is artificially self‐assembled on the surface of the zinc anode by graft‐modified fluorinated monomer (polyacrylic acid‐2‐(Trifluoromethyl)propenoic acid, PAA‐TFPA), on which an organic–inorganic hybrid (PAA‐Zn/ZnF2) solid electrolyte interface (SEI) with excellent ionic conductivity is formed by interacting with Zn2+. Both the pouch cell and fiber zinc anode exhibit excellent plating/stripping reversibility after protecting by this organic–inorganic SEI, which can be stably cycled more than 3000 h in symmetric Zn||Zn cells or 550 h in fiber Zn||Zn cells. Additionally, this interface layer preserves zinc anode with excellent mechanical durability under various mechanical deformation (stably working for another 1200 h after bending 100 h). The corresponding PAA‐Zn/ZnF2@Zn||MnO2 full cell displays an ultra‐long life span (79% capacity retention after 3000 cycles) and mechanical robustness (85% of the initial capacity for another 3000 cycles after bending 100 times). More importantly, the as‐assembled cells can easily power smart wearable devices to monitor the user's health condition.

Mussel-Inspired Fabrication of an Environment-Friendly and Self-Adhesive Superhydrophobic Polydopamine Coating with Excellent Mechanical Durability, Anti-Icing and Self-Cleaning Performances

Superhydrophobic coatings play a crucial role in self-cleaning and anti-icing infrastructure areas under harsh service environments such as very low temperature, strong wind, and sand impact. In the present study, an environment-friendly and self-adhesive superhydrophobic polydopamine coating inspired by mussels had been successfully developed and its growth process was accurately regulated by formula and reaction ratio optimization. The preparation characteristic and reaction mechanism, surface wetting behavior, multi-angle mechanical stability, anti-icing, and self-cleaning tests were systematically investigated. The results showed that the superhydrophobic coating achieved an ideal static contact angle of 162.7° and a roll-off angle of 5.5° through the proposed self-assembly technique in an ethanol-water solvent. This was due to the coupling effect of constructing a hierarchical roughness structure on the coating surface and reducing its surface energy, which had been well documented by the surface morphology characteristic and chemical structure analysis. The as-prepared coating's self-mechanical performances (tensile strength/shear holding power) and surface wear resistance (sand impact/sandpaper abrasion) behaviors were tested, and results showed tight internal compactness and excellent mechanical robustness, respectively. Furthermore, the 180° tape-peeling on 100 cycles and pull-off adhesion tests indicated that the above coating had significant mechanical stability and an increased percentage (57.4%) of interface bonding strength (27.4 MPa) with steel substrate compared to pure epoxy/steel. This was attributed to the metal chelating capacity between polydopamine catechol moieties and steel. Finally, the superhydrophobic coating had obvious self-cleaning properties by using graphite powder as a contaminant. Additionally, the coating had a higher supercool pressure and displayed much-reduced icing temperature, a longer icing delay time, and an extremely low and stable ice adhesion strength (0.115 MPa) owing to the extreme water-repellence and mechanical durability.

Active-Matrix Driven Flexible Pressure Sensor Array Using Oxide Thin-Film Diode

Active-matrix (AM) flexible pressure sensor is more advantageous than a passive-matrix in terms of power consumption, contrast, and crosstalk problems. Particularly, the AM platform is frequently adopted in wearable electronic systems for accurate data processing because it offers real-time interaction between humans and the external environment. Based on the above, we reported that AM driven flexible pressure sensor array integrated with an oxide thin-film diode and AgNW-coated microstructured polydimethylsiloxane sheet. The pressure sensor exhibited a high sensitivity of 0.6 Pa <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> at a low-pressure regime (<1 kPa) and a short response time of 70 ms, as well as excellent electrical uniformity and mechanical durability. Additionally, upon applying the AM operation, the pressure sensor array accurately identified the selected cell to which the pressure was applied without any sneak current, unlike the passive matrix operation. Consequently, the proposed AM driven flexible pressure sensor shows promising applicability as a building block for advanced wearable platforms.
