TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The sheet or membrane structure is prepared in sintered or unsintered form with or without 18% wetting liquid and optionally comprising material additions up to 90 vol.% of at least one of: additive containing an inorganic filler of micron size; additive containing reinforcements including (a) inorganic reinforcement e.g. glass fibers, carbon fibers, ceramic fibers, and polymeric fibers e.g. polyimides, (b) anisotropic polytetrafluoroethylene micro-pulverized fibrils unsintered, (c) anisotropic fibrous polytetrafluoroethylene (Du-Pont TEFLON 7 (RTM: Polytetrafluoroethylene)), (d) anisotropic micronized PTFE resin with a particle size of approximately 25 mu ; and/or additives containing micron size as polymerized unmelted melt processable polymeric particles capable of withstanding the processing temperature of polytetrafluoroethylene resin including (e) fluoropolymer resins e.g. tetrafluoroethylenehexafluoropropylene copolymer resin (FEP), poly(chlorotrifluoroethylene) resin (CTFE), perfluoroalkoxy tetrafluoroethylene copolymer resin (PFA), ethylenechlorotrifluoroethylene copolymer resin(E-CTFE), ethylenetrifluoroethylene copolymer resin (E-TFE) and poly (vinylidene fluoride) resin (PVDF), (f) non-fluoropolymer resins including polyether ether ketone (PEEK), polyether ketone (PEK), polyethersulfone (PES) and polyphenylene sulfide (PPS). The inorganic filler of micron size is below 25 mu in size. The additive is an extractable poreformer of known size e.g. calcium carbonate, and the composition is further processed after sintering, and the extractable poreformer is extracted from the sheet or membrane to provide a porous sheet or membrane whose pore size is replicated by the poreformer. The sheet or membrane structure retains wetting liquid (18%), where the sheet or membrane is multilayered in functional sequence without the use of adhesives to produce a composite functional laminate structure, and the product is produced in any width continuously by layering, wet compressing, drying below 300 degrees C, and sintering at 327-400 degrees C (preferably at 380 degrees C) depending on product thickness. The sheet or membrane is porous and contains a filler addition that is not fugitive that remains in the structure, where filler particles contain porous molecular sieves that contain angstrom size pores, and the volatile pore content acts as a blowing agent when the structure is sintered but remain in the structure to selectively remove certain gases and liquids and to act as a support for catalysts and conductive materials e.g. platinum and other rare metals. The PTFE sheet or membrane (in sintered or unsintered form) comprises (wt.%): 0.03 average micron carbon black (16) (Vulcan 72 (RTM: Carbon black)); silica 7 mu (Opal Supersil) (55); and PTFE (TEFLON 6 (RTM: Polytetrafluoroethylene)) coagulated dispersion resin (29) processed at 125 degrees C, where the composition containing carbon black and silica is laminated between porous layers of PTFE sheet, dried but unsintered or between sintered sheet, the composition layer has unusually uniform volume resistivity (ohms-cm) over the face of the sheet, and the copper electrodes implanted in the conductive layer characterize the uniform resistive properties and uniform heating qualities over the entire surface. The PTFE resin acts as a diluent for perfluorosulfonic acid (PFSA)/PTFE copolymer to thermally stabilize the membranes x, y dimensions in service and to improve strength. Only the PTFE and PFSA resin contains a pore former to create membrane pores of predictable size with varying pore surface area. The extractable poreformer is calcium carbonate and can be extracted with hydrochloric acid. The PTFE resin structure containing a pore forming filler that contains molecular sieves with pores that can perform selective filtering functions to remove or retain liquids or gases or contain catalysts or highly conductive fillers within and on their nano-porous surfaces to provide greatly expanded surface area contacts, where the molecular sieve pores contain liquids or gases that volatilize and expand during the drying and sintering steps to blow microscopic pores in the PTFE matrix and provide a porous product which is tough, rubbery and has a very low density, high surface area and the dimensional stability of the PTFE matrix. The roll of unsintered fiber-mat product comprises wetting liquid (18%) available in suitable thicknesses for further processing as sheet, laminate, compression molding or feed for mixing as coating compositions, where wetting liquid is added at ambient temperature to the product for direct use. The continuous length multi-directional planar oriented isotropic PTFE sheet or membrane is provided in laminated form and comprises the additives which are the fillers, reinforcements, alloying polymers or pore formers. The 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 contains functional components and the laminate assembly bonded thermally without the use of adhesives suitable to provide high conversion efficiency, with long life, continuously processed in long lengths, comprising: (a1) an anode and cathode with embossed surface channels to provide a path for electrons freed from hydrogen molecules to enable their use as an external circuit and to disperse the hydrogen molecules equally over the catalyst surface; (b1) water repellent catalyst membrane layers containing PTFE and a high conductivity micron size composition, e.g. platinum, or a mix of platinum and carbon, in porous or non-porous PTFE form or a laminate of both; and/or (c1) porous conductive membranes, where one is placed on either side of the catalyst membrane of (b1); or optionally plus other possible layers to provide one functional unit of a multiple stack; #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; #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.
