29Si CP/MAS and 13C CP/MAS measurements were carried out for epoxy-silica hybrids treated at 200 graduate C and 300 graduateC. For each sample, the 29Si spin lattice relaxation time was evaluated and compared with the corresponding values for reference samples prepared under the same conditions but without epoxy compound. This work clearly shows the sensitivity of the 29Si T1 to the morphology of composite materials. The mechanism of thermal decomposition is proposed on the basis of 13C CP/MAS experiments and analysis of changes of the 29Si T1 relaxation time.
