Abstract

Inorg./polymer composite thin films were prepd. by crosslinking a PDMS vinyl-terminated polymer in the presence of garnet pigments. The influence of the inorg. particles on the crosslinking of the composite system is studied by varying different conditions: a) concn. of the fillers, b) temp. of the crosslinking reaction and c) ratio crosslinker/vinyl groups (H/V). The crosslinking reactions are followed by in situ ATR-IR spectroscopy. The first results show a clear influence of the garnets on the crosslinking rate of the PDMS system and on the final conversion of the crosslinker reactive groups. The investigation of the reactions and mechanisms undergoing during the crosslinking of the composite, as well as the understanding of the inorg. particles effect, will allow the optimization of the crosslinking reactions in PDMS based particulate systems, in order to avoid post-crosslinking side reactions on coatings, triggered by residual crosslinker, catalyst and/or PDMS monomer.
