    摘要： A gradient nanofiber non-woven contains a plurality of nanofibers where at least 70% of the nanofibers are bonded to other nanofibers. The nanofibers each have a surface and a center and contain a bulk polymer and a third component. The majority by weight at the surface of the nanofiber is the third component and the majority by weight at the center of the nanofiber is the bulk polymer and there is a concentration gradient from most concentrated to least from the surface of the nanofiber to the center of the nanofiber. The process for forming a gradient nanofiber non-woven is also disclosed.

    摘要： A high-stretchable high-sensitive flexible force-sensitive sensing fiber and a preparation method therefor comprising the specific preparation method is as follows: uniformly and synergistically dispersing a one-dimensional (1D) nanowire/nanotube and a two-dimensional (2D) conductive sheet layer in a thermoplastic elastomer solution; formulating a uniform dispersion solution of a certain concentration; and using a wet spinning process to prepare an elastic composite fiber with a highly oriented 1D/2D hybrid network. The above-described composite fiber is placed in a metal precursor solution to fully swell, and then placed in reductive steam for reduction, to reduce metal precursors to zero-dimensional (0D) metal nanoparticles, thereby preparing a flexible force-sensitive sensing fiber based on a 0D/1D/2D three-dimensional collaborative network.
