原始语种摘要: Abstract(#br)Utilization of membranes for separation of macromolecules has gained wide interest in the last decade, especially after the development of smart membranes with tunable properties for improved separation performance. In this work, we fabricated hybrid membranes with variable pore sizes that depend on the pH of the environment. Hybrid membranes were prepared by conformally coating the pore walls of anodic aluminum oxide (AAO) templates with the pH sensitive poly(methylacrylic acid- co -ethylene glycol dimethacrylate) (p(MAA- co -EGDMA)) polymer using initiated chemical vapor deposition (iCVD). Performance of the membranes was investigated under different pH conditions using nanoparticles, polyacrylic acid (PAA) and BSA protein as permeates. Reduced pore sizes at pH 9 due to...
