Özet

An organically modified silicate-based material system with epoxy functionality was synthesised by the sol-gel method using some certain Si- and Ti-alkoxide precursors. The resultant system was processed with ultraviolet (UV)-radiation. Influences of certain synthesis and process parameters, including Ti content, sol ageing time, and UV-irradiation time, on various properties of the system were detailed. Overall results demonstrated that Ti-based precursors and UV-radiation could be employed to modify the microstructure, and that the final properties of the system might be tuned by an optimal combination of these two parameters. This preliminary study therefore revealed that this technique described herein might be used to develop a new process regime to obtain materials of this type with desired properties.
