Abstract The influences of silver nanowire p re p aration p rocess and silver nanowire additive amount on p ro p-erties were studied.Silver nanowire was p re p ared with the method of h y drothermal reaction p ol y vin y l py rrolidone/ silver nanowire com p osite fiber was p re p ared b y electrostatic s p innin g.The microto p o g ra p h y of com p osite nanofi-ber with the silver nanowire under different reaction conditions and with different silver nanowire contents were tested.The test results showed that the mor p holo gy of silver nanowires was ideal when it was obtained after the solution was p laced30mins and the h y drothermal reaction was ha pp ened for24h at180?.When the silver nanowire mass fraction in com p osite nanofiber was u p to5%,it had obvious antibacterial p ro p ert y.The com p osite nanofiber with the silver nanowire mass fraction of8%had better p hotocatal y tic p ro p ert y.It is considered that the p ol y vin y l py rrolidone/silver nanowire com p osite nanofiber has better antibacterial p ro p ert y and p hotocatal y tic p ro p ert y.
