NOVELTY - Multi-directional planar oriented isotropic polytetrafluoroethylene (PTFE) resin structure prepared from standalone staple length isotropic micro-fibers produced from nano crystallites obtained from the contents of spheroidal as polymerized dispersion particles (nearly 100% crystalline), is claimed. The isotropic staple length micro-fibers are formed by wetting liquid slurry which provides liquid shear to penetrate and release nano size crystallites from PTFE dispersion particles that reform in liquid shear stream and by diluting liquid slurry to provide a homogeneous mix.    USE - The multi-directional planar oriented isotropic PTFE resin structure is useful: as a sheet, membrane, or other structures in fuel or solar cells, in electrode or resistance heaters; to prepare a multi-directional planar oriented isotropic PTFE resin asymmetric filter membrane which is useful in purification of liquids that are used in electronics and pharmaceutical industry; and to prepare laminated PTFE resin multi-directional planar oriented isotropic form stable fuel cell matrix, and a roll of unsintered fiber-mat product (all claimed).    ADVANTAGE - The multi-directional planar oriented isotropic PTFE resin structure: produces products with greatly improved properties and much broader utility; provides a cost effective method to produce fuel and solar cells and related products e.g. porous electrodes that are needed to easily fabricate long lengths of layered flat membrane or sheet structures continuously with long life (greater than 20 years) and retained flexibility; and avoids particle handling and fabrication problems of PTFE resin.    DETAILED DESCRIPTION - Multi-directional planar oriented isotropic polytetrafluoroethylene (PTFE) resin structure prepared from standalone staple length isotropic micro-fibers produced from nano crystallites obtained from the contents of spheroidal as polymerized dispersion particles (nearly 100% crystalline), is claimed. The isotropic staple length micro-fibers are prepared and rapidly formed by wetting liquid slurry at 125 degrees C which provides liquid shear to penetrate and release nano size crystallites from PTFE dispersion particles that reform in the liquid shear stream as staple length micro-fibers that bulk quickly and further diluting the liquid slurry provides a homogeneous mix, where the homogeneous mix is deposited to form a uniform fibermat of interlocking multi-directional staple length microfibers. The PTFE fiber-mat is compressed at low pressure and dried simultaneously below 300 degrees C then sintered at 327-400 degrees C. The structure of the PTFE fiber-mat before and after sintering has equal strength in any direction in the plane of the PTFE fiber-mat surface. The length and width (the x and y dimensions) of the PTFE fiber-mat remain stable with temperature change, where the changes in volume of the PTFE fiber-mat due to temperature occurs in thickness (z dimension), and the dried and sintered PTFE fibermat retains the above properties as a sheet, membrane, or other structures. INDEPENDENT CLAIMS are also included for:    (1) a multi-directional planar oriented isotropic coating product using the fiber-mat mix as a coating product for dipping, casting, spraying, roller coating, coat hanger casting or impregnation, where the coating (comprises additives) does not have a critical cracking thickness of less than 1 mil, and does not contain dispersing agents, where coatings thicker than 5 mils can be applied in a single application;    (2) a multi-directional planar oriented isotropic PTFE resin asymmetric filter membrane comprising layers of the multi-directional planar oriented isotropic PTFE sheet or membrane, where the asymmetric filter is capable of removing particles down to atomic size;    (3) a laminated PTFE resin multi-directional planar oriented isotropic form stable fuel cell matrix which is prepared using the multi-directional planar oriented isotropic PTFE structure;    (4) a laminated PTFE resin based multi-directional planar oriented isotropic form stable matrix for photovoltaic solar cell components and suitable for generating solar energy prepared using the multi-directional planar oriented isotropic PTFE structure, where the matrix comprises copolymers and the polytetrafluoroethylene and its copolymer matrix used for some layers has no absorption bands of consequence from the visible region up to a strong opacity at 8-8.7 mu m, and the PTFE's transparency provides a matrix to hold multi-layered functional layered filled structures including: solar radiation absorbers in the base layer e.g. forms of silicon, or other conductors, the ability to emboss patterns in the base layer to concentrate solar radiation; a matrix for adding layers of diffusers and or reflectors; a top layer containing ethylenechlorotrifluoroethylene (E-CTFE) to improve the long time friction and wear characteristics of the structure, with proven life longer than 20 years;    (5) a product produced using the multi-directional planar oriented isotropic PTFE structure, where the structure contains 18% wetting liquid, and the product is used as product for conventional art compression molding to produce products with greatly improved properties and much broader utility;    (6) a sheet section of a product produced using the multidirectional planar oriented isotropic PTFE structure containing 18% wetting liquid formed, shaped, and embossed to provide complex surface patterns in products;    (7) PTFE nano crystallite products, alloyed with unmelted fluff or powder of melt processable resins to increase resin melt viscosity and make molding practical, where alloyed melt processable polymers can be biaxially planar oriented and processable by any method;    (8) a laminate of two or more multi-directional planar oriented isotropic PTFE structures prepared as sheets, compressed while containing 18% wetting liquid, compressed and dried simultaneously below 300 degrees C, then sintered below 400 degrees C, and thermally bonded without the use of adhesives;    (9) a roll of unsintered fiber-mat product prepared using the multi-directional planar oriented isotropic PTFE structure, where rolls of dried fiber-mat product is available in suitable thicknesses for further processing as sheet, laminate, compression molding feed, or for backward integration into coating compositions, and the wetting liquid is mixed in at ambient temperature; and    (10) continuous lengths of multi-directional planar oriented isotropic PTFE sheet or membrane, where the product comprises nano crystallites of PTFE, and may be filled, reinforced, porous, alloyed or be included together, or as crystallites of PTFE alone.
