- Abstract
The functionalization of poly(ester-urethane) ( PUR) surface was conducted using radiation-induced grafting. A thermosensitive layer constructed from N-isopropylacrylamide ( NIPAAm) was introduced onto a polyurethane film and characterized using attenuated total reflection Fourier transform infrared and X-ray photoelectron spectroscopies and contact angle measurements. Size exclusion chromatography was used to analyse the PUR- graft- PNIPAAm copolymers and homopolymers formed in solution. Additionally, reversible addition-fragmentation chain transfer ( RAFT) polymerization was performed in order to obtain PNIPAAm-grafted surfaces with well-defined properties. Atomic force microscopy was used to evaluate the surfaces synthesized via conventional and RAFT-mediated grafting methods. The results of various techniques confirmed the successful grafting of NIPAAm from PUR film. © 2015 Society of Chemical Industry
