Abstract

Abstract

SiO₂-GO nanohybrid particle was produced via insitu hydrolysis. Through adding SiO₂, GO, SiO₂-GO nanohybrid particles and polyvinylpyrrolidone (PVP) respectively, the polyvinylidene fluoride(PVDF) hybrid membrane was first prepared through phase inversion by an immersion precipitation technique. The pure water flux, contact angle, fouling recover rate of PVDF hybrid membrane etc were determined. The results show that the contact angles of SiO₂-GO/PVDF-PVP hybrid membrane decrease from 78.4° to 66.02°. The rejection rate of bovine serum albumin (BSA) exceeds 81.5% under high water flux (1 018 L/(m²·h)) and the membrane fouling recovery rate is highest (BSA=78.65%). The results show that the synergistic effect of SiO₂-GO nanohybrid particles and PVP improve the properties and antifouling ability of hybrid membrane.
