Bioinspired by the spinning of spider silks,the biomimetic preparation of nano-silica/polyurethane（nano-SiO/TPU） elastomeric fibers with distinctive multi-scale microstructures was successfully *** formation mechanism of the nano-SiO;/TPU fibers was considered as the integrated mechanism of diffusion,coagulation,self-assembly,and microphase separation,same as that of the native spider *** mass ratio of nano-SiO;to TPU greatly influenced the external and inner microstructures of the nano-SiO;ATPU *** formation process of the nano-SiO;/TPU fibers was simply described as three main stages,and the second stage,such as the adding of the ethanol solvents and nano-SiO;in different diameters,was thought to be very crucial for the final external and inner microstructures of the prepared *** example,the adding of the ethanol and the nano-SiO;spheres in diameter of 10 nm resulted in the existence of many TPU-self-assembled microspheres mostly spaced apart by the nano-SiO;aggregates in the nano-SiOVTPU fibers,while the adding of the ethanol and the nano-SiO;spheres in diameter of 100 nm resulted in the existence of the nano-SiO;spheres,instead of the TPU-self-assembled microspheres,distributed in the nano-SiO;/TPU fibers.

Bioinspired by the spinning of spider silks,the biomimetic preparation of elastomeric fibers with micro/nano structures on the surfaces was attempted,and as a result,three types of ultrafine fullvulcanized powdered nitrile-butadiene rubber(UFPNBR)/thermoplastic polyurethane(TPU) fibers were *** first fiber was only decorated by the micron-sized grooves on the surface,and the second fiber was dotted by both the micron-sized grooves and nanometer-sized spheres on the surface,while the third fiber was helical and with a concave-convex *** biomimetic preparation mainly consisted of four steps,and the formation mechanism was described as an integrated mechanism of diffusion,coagulation,self assembly,and microphase *** micro/nano structures on the fibers were controlled by changing the mass ratio of UFPNBR to TPU and environment of vertical *** UFPNBR/TPU elastomeric fibers were hoped to have an integrated function of superhydrophobicity,self cleaning,and mechanical improvement of toughness or strength.
