A series of novel organic-inorganic hybrid materials of inorganic 3-acryloxypropyl trimethoxysilane, 3-aminopropyltrimethoxysilane and various organic diols, e.g. 4,4’-(hexafluoroisopropylidene)diphenol were synthesized by a facile non-hydrolytic sol-gel processing at 80oC under dry N2 condition. Under the simple exposure of UV irradiation, crack-free, thick composite films with excellent mechanical properties were produced with no remaining traces of solvents. To measure CO2 sensing ability, we carefully monitored the changes of the optical properties of the spin-coated films. Carbamate groups were formed by chemical bonding with CO2 and amine functional groups of our hybrid materials. The morphology and chemical structure of these films were investigated by electron microscopy and FTIR. |
