| 1 | Advanced Functional Fiber and Smart Textile显示文摘The research and applications of fiber materials are directly related to the daily life of social populace and the development of relevant revolutionary manufacturing industry.However,the conventional fibers and fiber products can no longer meet the requirements of automation and intellectualization in modern society,as well as people’s consumption needs in pursuit of smart,avant-grade,fashion and distinctiveness.The advanced fiber-shaped electronics with most desired designability and integration features have been explored and developed intensively during the last few years.The advanced fiber-based products such as wearable electronics and smart clothing can be employed as the second skin to enhance information exchange between humans and the external environment.In this review,the significant progress on flexible fiber-shaped multifunctional devices,including fiber-based energy harvesting devices,energy storage devices,chromatic devices,and actuators are discussed.Particularly,the fabrication procedures and application characteristics of multifunctional fiber devices such as fiber-shaped solar cells,lithium-ion batteries,actuators and electrochromic fibers are introduced in detail.Finally,we provide our perspectives on the challenges and future development of functional fiber-shaped devices. | Qiuwei Shi Jianqi Sun Chengyi Hou Yaogang Li Qinghong Zhang Hongzhi Wang | 2019 | Advanced Fiber Materials2019，1，1： | 7 |
| 2 | Light-driven artificial muscles based on electrospun microfiber yarns显示文摘Artificial muscles are widely potential in diverse fields including medical treatment, humanoid robotics and industrial automation. Soft materials due to bio-friendly interaction are suitable for those applications. Planar and fiber shape based artificial muscles that use the polymer as substrate materials can be triggered by various stimuli like electric, moisture and heat. Here,artificial muscles based on electrospun microfiber yarns are demonstrated, which can be remotely controlled. The carbon nanotubes embedded in polyurethane microfibers enable the yarns to efficiently absorb near-infrared light and radiate heat,which induces the fast temperature change that leads to the contraction/expansion motions along the axial direction. Microfiber mats are collected by a rotating cylinder that results in highly oriented alignment. The yarns from microfiber mats are highly twisted into the coiled structure, which generates maximum contractive actuation of 6.7% at 70°C. 1000 cycles were demonstrated without an obvious decline of actuating performances. The light-driven artificial muscles can be potentially applied in wireless control, bio-medical devices and so on. | MENG JunXing HOU ChengYi ZHANG QingHong LI YaoGang WANG HongZhi | 2019 | Science China(Technological Sciences)2019，62，6： | 3 |
| 3 | MoS2/C/C nanofiber with double-layer carbon coating for high cycling stability and rate capability in lithium-ion batteries显示文摘MoS2 has attracted a lot of interest in the field of lithium-ion storage as ananode material owing to its high capacity and two-dimensional (2D)-layerstructure. However, its electrochemical properties, such as rate capability andcycling stability, are usually limited by its low conductivity, volume variation, andpolysulfide dissolution during lithiation/delithiation cycling. Here, a designedtwo-layer carbon-coated MoS2/carbon nanofiber (MoS2/C/C fiber) hybrid electrodewith a double-layer carbon coating was achieved by a facile hydrothermal andsubsequent electrospinning method. The double carbon layer (inner amorphouscarbon and outer carbon fiber) shells could efficiently increase the electronconductivity, prevent the aggregation of MoS2 flakes, and limit the volumechange and polysulfide loss during long-term cycling. The as-prepared MoS2/C/Cfiber electrode exhibited a high capacity of up to 1,275 mAh/g at a currentdensity of 0.2 A/g, 85.0% first cycle Coulombic efficiency, and significantlyincreased rate capability and cycling stability. These results demonstrate thepotential applications of MoS2/C/C fiber hybrid material for energy storage andmay open up a new avenue for improving electrode energy storage performanceby fabricating hybrid nanofiber electrode materials with double-layer carboncoatings. | Hao Wu Chengyi Hou Guozhen Shen Tao Liu Yuanlong Shao Ru Xiao Hongzhi Wang | 2018 | Nano Research2018，11，11： | 2 |

| 9 | Dielectrophoretic Assembly of Carbon Nanotube Chains in Aqueous Solution显示文摘Carbon nanotubes(CNTs)have generated remarkable interests in a wide range of research fields due to their excellent electri-cal properties.However,achieving the CNTs arrangement with high quality in a short time remains a challenge.Herein we studied the in-situ assembly of CNTs based on macroscopic dielectrophoresis by using a centimeter scale electrode,which overcome the limitation of small size in traditional method for manipulating nanoparticles.Ordered CNTs chains could be obtained under the action of alternating current dielectrophoresis by optimizing the voltage and frequency.Besides,the ordered chains were able to restore immediately upon powering up after being damaged.Furthermore,a CNTs chain was prepared for conducting the wet circuit and powering a LED,and different conductive patterns on the non-woven fabric were achieved by controlling the position of the electrodes in wet environment. | Dan Zhao Rui Liu Cheng Luo Yang Guo Chengyi Hou Qinghong Zhang Yaogang Li Wei Jia Hongzhi Wang | 2021 | Advanced Fiber Materials2021，3，5： | 1 |
| 10 | Research on Flexible GaInP/GaInAs/Ge/Bi2Te3/Sb2Te3 PV-TE Integrated Systems显示文摘An optimal structure design of the lattice mismatched GaInP/GaInAs/Ge solar cell with high photoelectric conversion efficiency was proposed. Two-dimensional Bi2Te3/Sb2Te3 nanosheets were prepared by solvothermal synthesis method used as thermoelectric(TE) functional materials, which is further hybrid with high conductive reduced graphene oxide(rGO) and carbon nanotubes(CNTs). TE film was then fabricated based on above materials. The power factor of the n-type TE film is 19.31 μW/mK2, and the power factor of the p-type TE film is 97.40 μW/mK2. The flexible TE device was integrated with flexible solar cell. Compared with the single photovoltaic(PV) cell, the efficiency of the as-prepared flexible integrated device measured under the AM1.5 illumination is significantly improved. The efficiency of the two parallel tests is increased from 27.26% and 26.59%, to 29.11% and 28.92%, respectively. The increasing ratio reaches 6.7%-8.8%. | 高鹏 CHEN Lilin WU Bo ZHANG Qiming XUE Chao HOU Chengyi SUN Qiang | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，4： | 0 |
| 11 | High-Performance Ionic Thermoelectric Supercapacitor for Integrated Energy Conversion-Storage显示文摘Converting low-grade waste heat into usable electricity and storing it simultaneously requires a new technology that realize the directional migration of electrons or ions under temperature difference and enrichment on the electrodes.Although the urgent demand of energy conversion-storage(ECS)has emerged in the field of wearable electronic,achieving the integrated bi-functional device remains challenge due to the different mechanisms of electrical transportation and storage.Here,we report an ionic thermoelectric supercapacitor that relies on the synergistic functions of thermoelectricity and supercapacitor in the thermoelectric ionogel electrolyte and high-performance hydrogel electrodes to enhance the ECS performance under a thermal gradient.The thermoelectric electrolyte is composed of polyacrylamide hydrogel and sodium carboxymethyl cellulose(PMSC),possessing cross-linked network with excellent cation selectivity,while the ionic thermoelectric properties are further improved in the presence of NaCl.The corresponding Seebeck coefficient and ionic conductivity of the NaCl–PMSC electrolyte reach 17.1 mV K^(-1)and 26.8 mS cm^(-1),respectively.Owing to good stretchability of both gel-based electrolyte and electrode,the fullstretchable integrated ECS device,termed ionic thermoelectric supercapacitor,presents promising thermal-charge storage capability(~1.3 mC,ΔT≈10 K),thus holds promise for wearable energy harvesting. | Xinyu Yang Yuqing Tian Bo Wu Wei Jia Chengyi Hou Qinghong Zhang Yaogang Li Hongzhi Wang | 2022 | Energy & Environmental Materials2022，5，3： | 0 |
