Investigation of one-dimensional multi-functional zwitterionic Ag nanowires as a novel modifier for PVDF ultrafiltration membranes

This work presented a novel kind of one-dimensional multi-functional modifier for membrane materials. Cysteine modified silver nanowires (C-AgNWs) were used to modify polyvinylidene fluoride (PVDF) membranes and the comprehensive optimized properties including separation efficiency, mechanical strength and antifouling ability of PVDF membranes demonstrated that monodisperse, orientated and zwitterionic C-AgNWs were an efficient modifier for the PVDF ultrafiltration membrane. The objective of this work was to comprehensively improve the application performance of polymer materials using the special hybrid mechanism of one-dimensional nanomaterials.
