Abstract

There is considerable current interest in plasma and corona treatment of silicones. It is well established that a thin, silica-like layer is created on the surface by such treatments. Much fresh insight has emerged concerning the role of low-molecular-weight materials in the hydrophobic recovery of treated elastomers. Even if these diffusible species are removed before treatment, hydrophobic recovery still occurs above a threshold energy implying that they are produced in situ by the treatment. A particularly significant new direction in the plasma treatment field is plasma polymerization of organosilicon monomers using atmospheric pressure glow discharge (APGD).

I am indebted to Andy Goodwin, Stuart Leadley, and Lesley-Ann O’Hare of Dow Corning Plasma Solutions (Cork, Eire) and Jongsoo Kim and Manoj Chaudhury of Lehigh University (Bethlehem PA, USA) for their many contributions to these plasma/corona studies.
