Method for Increasing Fracture Toughness and Reducing Brittleness of Semi-Crystalline Polymer

Abstract

A manufacturing process is provided to increase fracture toughness and reduce brittleness for a semi-crystalline polymer material. A material such as poly(vinylidene fluoride-trifluorethylene) or p(VDF-TrFE) is placed in an inert oxygen-free atmosphere and heated to a temperature that is greater than room temperature but below the melting temperature of the material. The material is then Irradiated with beta particles until a desired level of fracture toughness is achieved where fracture toughness is a function of the radiation dose.
