摘要: Surface modification methods based on a combination of plasma and chemical treatments render an unfilled butyl rubber surface highly reactive toward organosilanes, allowing formation organosilane self-assembled monolayer (SAM). Plasma oxidation the followed by vapour deposition SiCl4 produces hydrophilic suitable for anchoring organosilanes. Fabrication SAMs this with n-octadecyltrichlorosilane (OTS) trichloro(1H,1H,2H,2H-perfluorooctyl)silane (FOTS) via resulted in 15% 25% decrease gas permeability, respectively, no change optical transparency rubber.
