We explore the fabric structural effect of thermoelectric textiles on power generation and achieve high density for practical applications.
Graphene fiber-based supercapacitors (GFSCs) hold high power density, fast charge–discharge rate, ultralong cycling life, exceptional mechanical/electrical properties, and safe operation conditions, making them very promising to small wearable electronics. However, the electrochemical performance is still limited by severe stacking of graphene sheets, hydrophobicity fibers, complex preparation process. In this work, we develop a facile but robust strategy easily enhance properties...
Hierarchically porous, micropore-domain graphene-based fiber-shaped supercapacitors show high energy density.
A simple and versatile step-by-step strategy is utilized to construct multilayer structured coatings for high-efficiency electromagnetic interference (EMI) shielding. The construction realizes the excellent controllable EMI shielding as well fast thermal dissipation satisfied stability. This work demonstrates advantages of nanostructure in provides a new designing high-performance materials. As service our authors readers, this journal supporting information supplied by authors. Such...
Fiber and/or yarn-shaped supercapacitors (FSSCs) have tremendous potential applications in portable and wearable electronics because of their light weight, good flexibility, weavability. However, FSSCs usually show low energy density, which hinders wide electronics. It remains challenging for the to enhance densities without sacrificing flexibility mechanical properties. Herein, we develop a chemical polymerization strategy fabricate core–sheath porous polyaniline nanorods/graphene fibers...
Conductive coatings show great promise for next-generation electromagnetic interference (EMI) shielding challenges on textile; however, their stringent requirements electrical conductivity are difficult to meet by conventional approaches of increasing the loading and homogeneity conductive nanofillers. Here, axial alignment carbon nanotubes (CNTs) fibers that were obtained spontaneous capillary-driven self-assembly is shown commercial cotton fabrics, its potential EMI demonstrated. The...
Chemically converted graphene fiber-shaped supercapacitors (FSSCs) are highly promising flexible energy storage devices for wearable electronics. However, the ultralow specific capacitance and poor rate performance severely hamper their practical applications. They caused by severe stacking of nanosheets tortuous ion diffusion path in graphene-based electrodes; thus, utilization has been rarely carefully considered to date. Here, we address these issues developing three-dimensional...
Polypropylene and nylon 66 fabrics are subjected to atmospheric pressure He He-O 2 plasmas for selected exposure time intervals. Scanning electron microscopy anal ysis of the shows no apparent changes in plasma-treated fiber surfaces, but significant surface morphological polypropylene. Surface analyses filaments reveal small differences carbon oxygen contents between treated control groups. The nitrogen content polypropylene fabric increases significantly after treatment both plasmas. There...
Both air/He and air/O 2 /He atmospheric plasma treatments are applied to desize PVA on cotton, then PDR (percent desizing ratio) tensile strengths of cotton fabrics single yams measured. XPS SEM used analyze the effects pressure PVA. These can both remove some sizing significantly improve by washing, especially cold water washing. The treated with same as for unsized fabric. analysis films reveals surface chemical changes such chain scission formation polar groups, which promote solubility...
In recent years, the thermoelectric properties of inorganic/polymer composites have been markedly improved. However, enhancement mechanism in is still far from clear. this work, we fabricate a novel type composite by mixing high-mobility poly(3,4-ethylenedioxythiophene) nanowire with tellurium and investigate varying loading nanowires underlying mechanism. We find that addition can enhance power factor ∼40%. We, for first time, quantitatively interpret effect energy filtering on polymer...
Abstract With molecular dynamics simulations, nanocomposites were characterized that are comprised of a polyimide (PI) polymer and carbon nanotubes (CNTs) with the same outer diameter but one, two, or three walls. The simulations indicate PI/CNT interaction is strong, regardless number CNT walls, there some degree alignment PI chains near interface. As walls increased, density interface also increased average radius gyration decreased, these observations attributed to changes due intertube...
