Abstract
There are disclosed a novel PVF.sub.2 film of beta phase crystalline structure, predominantly, and a method for making it. The beta phase is achieved by first exposing a surface of an insulating polymeric support to an A.C. corona discharge treatment, and then casting molten PVF.sub.2 onto that exposed surface while chilling the cast PVF.sub.2.
