초록
In this study, the preparation of a temperature-responsive poly(N-isopropylacrylamide)(PNIPAAm)-grafted surface was performed using an eco-friendly and biocompatible ion beaminducedsurface graft polymerization. The surface of a perfluoroalkoxy (PFA) film was activatedby ion implantation and N-isopropylacrylamide (NIPAAm) was then graft polymerized selectivelyonto the activated regions of the PFA surfaces. Based on the results of the peroxide concentrationand grafting degree measurements, the amount of the peroxide groups formed on the implantedsurface was dependant on the fluence, which affected the grafting degree. The results of the FTIR-ATR, XPS, and SEM confirmed that the NIPAAm was successfully grafted onto the implantedPFA. Moreover, the contact angle measurement at different temperatures revealed that the surfaceof the PNIPAAm-grafted PFA film was temperature-responsive.
