摘要:
In this work, the effect of the side group of a series of silane coupling agents, as well as the subsequent anchoring of an imidazole derivative, for TiO2 particles, within the polypropylene polymeric matrix, with emphasis on their mechanical properties and their crystallization kinetics, and their rate of degradation. Differences were the following: the 3-Glicydoxypropyltrimethoxysilane was the best in photostability overall. On the other hand, 3-Chloropropyltrimethoxysilane promoted the degradation. All the other silane coupling agents avoided the an-atase's photocatalytic activity, inhibiting the polymer matrix's degradation.
