Amino-terminated glass surface was prepared by coupling 3-aminopropyltriethoxysilane
and the Cu2+-amino redox system was designed to initiate the radical polymerization of the electron-deficient monomers
such as N
N-dimethylacrylamide) in aqueous solutions.The results from attenuated total reflection-Fourier transform infrared spectroscopy
contact angle measurements
atomic force microscopy and X-ray photoelectron spectroscopy confirmed the formation of the glass substrate grafted with functional polymer chains.As there was no free polymer chains formed in the reaction mixtures
our approach provided a facile strategy for the preparation of organic/inorganic hybrid materials.The amount of materials m(CuSO4)∶m(DMAAm)∶m(H2O)=5∶1000∶1000 should be selected
80℃ should be selected as the suitable temperature
and 4 h should be selected as the suitable reaction time.The weight gain ratio and specific graft yield of GlassKH-550-g-PDMAAm were 0.342% and 0.47 mg/cm2.The results showed that chemical composition and microstructure on the glass surface changed obviously
and the effect of graft polymerization was very distinct.
