Abstract
Poly(tetrafluoroethylene) (PTFE) plates grafted with N-isopropylacrylamide (NIPAAm) and 2-hydroxy-N-isopropylacrylamide (HIPAAm) as hydrophilic monomers have been prepared by the combined use of the oxygen plasma treatment and photografting. The investigation of the surface compositions of the grafted PTFE plates was analyzed by ESCA and thermo-responsive property was investigated by contact angle measurements toward water. Estimating the introduction of P(NIPAAm-co-HIPAAm) onto the PTFE surface, the polymer in the reaction vessel was followed by 1H-NMR. ESCA spectra revealed the introduction of oxygen containing functional groups and PNIPAAm onto the PTFE plate. The phase transition temperature of the PTFE-g-P(NIPAAm-co-HIPAAm) rose with the ratio of PHIPAAm to PNIPAAm in the monomer solution. The temperatures for the ratio of PTFE-g-P(NIPAAm-co-HIPAAm) (N:H=70:30 and 50:50) were about 4°C and 55°C, respectively
