摘要
A method of producing a heat-resistant electrically charged fluororesin material is provided. The method comprises the steps of providing a fluorine-containing resin material; irradiating the fluorine-containing resin material with ionizing radiation at a temperature not lower than a crystalline melting point of the fluorine-containing resin material in absence of oxygen, thereby causing crosslinking in the fluorine-containing resin material to change the fluorine-containing resin material into a heat-resistant fluororesin material; and, electrifying the heat-resistant fluororesin material to form a heat-resistant electrically charged fluororesin material. The method may further comprises the step of heating the material following the step of electrifying. The successive steps of electrifying and heating are repeatedly conducted more than one time.
