    Abstract: The invention relates to novel linear, semi-crystalline fluoropolymers containing 0.5 to 25 mole percent of at least one vinyl ester monomer unit. At least 40 mole percent of the vinyl ester monomer units are present in the copolymer as single monomer units (not diads or triads or greater) between two fluoromonomer units. The invention also relates to a process for forming the fluoromonomers/vinyl ester copolymer. The fluoropolymer of the invention may be used in applications benefiting from a functional fluoropolymers including as a binder, or for use in forming hydrophilic membranes and hollow fibers.

    Abstract: This invention discloses a method of fabricating a reticulated solid electrolyte/separator (RSES) which is suitable both as electrolyte and separator in a solid state battery. The reticulated composite is produced by casting and drying of a slurry which exhibits a high yield stress (greater than 50 dyne/cm2) and comprised of a high MW resin dissolved in a solvent (having solution viscosity of higher than 100 cp at 5% in NMP at room temperature) and dispersed nanoparticles of solid electrolyte of high specific surface areas (i.e. greater than 1 m2/g, preferable greater than 10 m2/g) including but not limited to LLZO, LSP, or LIPON or derivatives thereof. This reticulated solid electrolyte/separator exhibits superior cycling properties and high ionic conductivity, resists lithium dendrite penetration, and maintains a high dimensional stability (less than 10% shrinking) at elevated temperatures (up to 140° C.). In addition, the present disclosure relates to electrochemical cells comprising such a reticulated film composite to act as both electrolyte and separator.

    Abstract: The invention relates to a porous separation article having a fluoropolymer or polyamide binder interconnecting one or more types of interactive powdery materials or fibers. The interconnectivity is such that the binder connects the powdery materials or fibers in discrete spots rather than as a complete coating, allowing the materials or fibers to be in direct contact with, and interact with a fluid. The resulting article is a formed multicomponent, interconnected web, with porosity. The separation article is useful in water purification, as well as in the separation of dissolved or suspended materials in both aqueous and non-aqueous systems in industrial uses. The separation article can function at ambient temperature, as well as at elevated temperatures.
