摘要： This invention relates to elastomeric coatings for electronics. Disclosed is a electronic device comprising a substrate layer, a conductive layer and an encapsulant layer. The encapsulant layer comprises at least a butyl rubber material. The butyl rubber encapsulant prevents a change in resistivity of the conductive layer following exposure to nitric acid vapour for 12 hours or hydrochloric acid vapour for 10 hours.

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 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.

摘要： The present invention provides an optically transparent peroxide cured article made from a peroxide curable butyl rubber ionomer comprising repeating units derived from the reaction product of one or more multiolefin monomers and at least one nitrogen or phosphorous based nucleophile comprising a pendant vinyl group. A process is also disclosed for making the optically transparent article.
