Isotropic nano crystallites of polytetrafluoroethylene (PTFE) resin and products thereof that are biaxially planar oriented and form stable

Abstract

The subject invention concerns the use of staple length nano polytetrafluoroethylene (PTFE) crystallites obtained by liquid shearing PTFE dispersion particles that are wet by a liquid with a surface tension below 30 dynes/cm this liquid will spread on PTFE resin surfaces and has a contact angle of zero (0) degrees with a PTFE surface. Staple length PTFE resin micro-fibers will form rapidly under high liquid shearing force at 125° C. when diluted 1 part PTFE resin to 20 parts liquid. The subject invention also includes the application of products that are multi-directional planar oriented and isotropic as sheet, membranes and structures useful for high performance filtering, fuel and solar cells and related energy applications. It also concerns products made from formulations as coatings and product for forming, shaping and molding sheet and structures of the subject invention and methods of adhering, bond and laminating components of these structures without adhesives.
