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

Abstract: A method of immobilizing a catalyst on a substrate surface involves providing novel ligating copolymers comprising functional groups capable of binding to a substrate surface and functional groups capable of ligating to catalysts such as metal ions, metal complexes, nanoparticles, or colloids; applying the ligating copolymer to a substrate surface to cause the ligating copolymer to bind thereto, and contacting the modified substrate surface with a solution of a catalyst, causing the catalyst to be ligated by the ligating copolymer and thus immobilized on the substrate surface. The ligating copolymer may be patterned on the substrate surface using a method such as microcontact printing.
