Hydrophilic modification of poly(vinylidene fluoride) ultrafiltration membranes by surface UV photo-grafting with N,N′-methylene-bisacrylamide as monomer and Ce(IV) as initiator

Abstract

A UV photo-grafting method was utilised to enhance the hydrophilicity and anti-fouling property of compared with the pure PVDF membrane when treating river water. For bovine serum albumin rejection and porosity measurements no significant changes were observed between pure PVDF and graft-treated membranes. The enhanced performance of the modified membrane in this work was moderate, but the UV irradiation duration (3 min) was short. The integrative effects of UV modification in this work were satisfactory when both irradiation duration and enhanced performance were considered.

“…[ 8 ] CA was grafted onto PVDF microporous membrane via free radical grating method. [ 9 ] Ce(IV) initiated chemical grafting of N , N ‐methylene bisacrylamide onto PVDF was reported by Shi et al [ 10 ] PVDF with –OH, –NH 2 , and –CO 2 H functionalities were done by Schulz et al [ 11 ] PEI grafted PVDF for pulse cleaning was reported by Ma et al [ 12 ] Similarly, PVDF was functionalized with protein.
