Abstract

Poly(tetrafluoroethylene) (PTFE) plates grafted with N-isopropylacrylamide (NIPAAm) as a thermosensitive monomer have been prepared by the combined use of the plasma treatment and photografting. In addition to the surface compositions of the grafted PTFE plates analyzed by ESCA and thermosensitive properties observed by contact angle measurements and the ellipsometry, -CONH groups attributed to PNIPAAm and even grafted layers of PNIPAAm prepared on plasma-treated PTFE plates are confirmed by an IR-ER method and by SEM, respectively.
