Abstract

Hydrophobic recovery of a number of plasma-treated polymers (polyethylene, polypropylene, polyethyleneterephthalate, polycarbonate and polystyrene) has been studied. For high molecular weight polymers, it occurs through segmental motions which bury polar groups away from the surface. The extent of crosslinking, along with mobility of segments, limits the contact angles which can be reached upon recovery. For low molecular weight polymers, macromolecular motions overcome segmental motions, and thus the recovery is determined by a mechanism involving diffusion through crosslinked network.
