Abstract
A silicone composition having anti-microbial properties contains well distributed silica and nanoparticles of a noble metal. Silica and nanoparticles of a noble metal are added to liquid vinyl-terminated polydimethylsiloxane. A coupling agent is then added to the mixture and heated, the coupling agent comprising trialkoxysilane having a formula RSi(OR), wherein Ris vinyl or allyl, and Ris an alkyl radical having from 1 to 3 carbon atoms. In one embodiment, trimethylsiloxy terminated polymethylhydrosiloxane is then added to the mixture and heated in the presence of a catalyst so as to cross-link and cure the same into a silicone elastomer. In another embodiment, in place of the trimethylsiloxy terminated polymethylhydrosiloxane, a peroxide is added to mixture and heated to form the silicone. In this later example, no catalyst is needed.
