In this study a hydroxylated glass surface was functionalized by 3-methacryl oxypropyl trimethoxysilane(MPS) monolayer followed by the photoinitiated radical polymerization graft of N-isopropylacrylamide(NIPAM) chemical bonded to the C C groups of MPS and used trimethylolpropane triacrylate (TMPTA)as cross-linking agent. Composition of the PNIPAM membrane grafted on the glass substrate was inves-tigated by attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR) and X-rayphotoelectron spectroscope (XPS). UV–vis tran**ittance and water contact angle were used to examinethe thermo-sensitivity. The results indicated that the PNIPAM reticulate membrane which was success-fully grafted on the surface of glass by covalent bonds performed good adhesive strength and stability. Dueto the property of discoloration with different temperature, PNIPAM membrane grafted on the surfaceof glass substrate had potential applications as temperature control switch device.
