Manipulation of Grafting Location via Photografting To Fabricate High-Performance Ethylene Vinyl Alcohol Copolymer Membrane for Protein Separation.

ABSTRACT: Ethylene vinyl alcohol copolymer (EVAL) membrane has great potential for applications in protein separation and purification, but the uncontrollable distribution of grafting location when membranes are modified by the grafting method limits the membrane performance. Herein, an effective strategy for controlling the distribution of grafting location was designed to fabricate a high-performance EVAL membrane via photografting. The UV intensity through the membranes was weakened when the local concentration of the photoinitiator benzophenone (BP) on the topside of the membrane increased; thus, the grafting location inside the EVAL membrane changed from homogenous to asymmetric distribution based on the UV absorbability of BP. The grafting inside the membrane pores can be promoted when the loo
