In the paper, a novel polyacrylonitrile/Ag/ZnO (PAN/Ag/ZnO) microporous membrane was prepared by sequentialelectrospinning, chemical silver plating and hydrothermal reaction. Morphology and structure of PAN/Ag/ZnO membraneand the photocatalytic performance of Rhodamine Bsolution under visible-light irradiation were systematically investigated. It was found that ZnO nanorod and ZnO nanosheet with hexagonal wurtzite structure were prepared in different concentrationof growth solution. The visible light photocatalytic performance test showed that ZnO nanorod had higher photocatalyticefficiency than ZnO nanosheet. After 6 hours of irradiation, the degradation efficiency of the RhB solution of PAN/Ag/ZnOfilm with only 2 mg of ZnO nanorods reached 98 %. After 5 times of repeated experiments, there was no notable decrease inthe performance. The photocatalytic performance of the material is enhanced by chemical silver plating. Compared with theunsilvered samples, the addition of Ag not only made the microporous film grow more ZnO, but also greatly improved thevisible light photocatalytic performance by forming Ag-ZnO metal-semiconductor interface.

In this research, non-fluorinated polyurethane/silica dioxide (PU/SiO2) nanofibrous webs were prepared byelectrospinning and hydrothermal treatment. Then the developed webs were laminated onto polyester woven fabrics toexamine their practical applications in the textile area. Investigation for surface morphology, pore size, water contact angle(WCA) and hydrostatic pressure was done in detail to examine the waterproofness and breathability of the PU/SiO2 nanofiberwebs and the laminated fabrics. The results showed that when Tetraethoxysilane concentration in electrospun solution was6 wt%, the fibrous web exhibited the desirable morphology, mechanical properties and hydrophobicity. At this time, SiO2nanoparticles dispersed uniformly on and in PU nanofibers and fibers had a more uniform diameter. The composite laminatedfabrics produced exhibited a value for hydrostatic pressure of 23.5 kPa with water vapor transmission rate (WVTR) of5.19 kg/m2/day.
