A novel high performance hydrophilic poly(vinyl alcohol-co-ethylene) (PVA-co-PE) nanofibermembrane for filtration
media was prepared and characterized in this study. The PVA-co-PE nanofibers for the membrane preparationwere
fabricated based on a high throughput, cost effective and environmental friendlymethod developed
by us. The basic properties of PVA-co-PE nanofibrous membrane and commercially available membrane (mixed
cellulose ester membrane) including morphology, pore size distribution, contact angle, mechanics, water flux
and filtration efficiency were investigated. The rejection rate of PVA-co-PE nanofibrous membrane (nanofiber
density is 3 g/m2) to TiO2 suspension was above 99%, and such unique hydrophilic nanofibrous membrane
exhibited a flux rate significantly higher than the commercial microfiltration membrane. The results indicated
that PVA-co-PE nanofibrousmembrane prepared by thismethodwas a hydrophilic and high performance membrane
which could be used in the microfiltration fields.
