THE SURFACE MODIFICATION OF NANO-SIZED POROUS MEMBRANE WITH CATECHOL CONJUGATED POLY(N-ISOPROPYL ACRYLAMIDE) FOR THERMAL RESPONSIVE DIFFUSION

摘要

In this study, we prepared PNIPAam of Mw 12,000 by RAFT polymerization with narrow dispersity (PDI 1.09). The end functional group of the synthesized PNIPAam was conjugated to catechol and fluorescence dye, respectively. Not only the surface but also the inside of the pores of anodized aluminum oxide membranes could be coated with PNIPAam, which was verified with confocal microscopy. Additionally, thermal responsiveness was demonstrated by static oil contact angle and permeability tests.
