Abstract

This paper reports on the effects of silicone oils, used as processing agents, on the recovery of hydrophobicity of silicone rubber. The recovery of hydrophobicity was evaluated by the measuring the contact angle, the surface electrical resistance and SEM. Here, we formed artificial contamination on the surface of samples, which scratched by sand papers and alumina powders. There was small recovery of hydrophobicity on the surface of SIR-A that silicone oil was not added. In both oil-added samples, SIR-B and SIR-C, recovery of hydrophobicity was achieved greatly. The surface of SIR-C showed that a lot of silicone oil was observed due to migration of oil, relatively in comparison with SIR-B. The tendency of recovery of hydrophobicity expressed by contact angle was in a good agreement with electrical property as determined by surface resistivity.
