  • Publication number: 20220372308
    Abstract: This invention discloses a reticulated film composite and a method of fabricating a reticulated film composite suitable as a 3 dimensional porous and conductive matrix which contains up to 80% porosity and exhibits high recovery after compression. The reticulated film composite is produced by casting and drying of a slurry which exhibits a high yield stress (i.e. greater than 50 dyne/cm2) and comprised of a high MW resin dissolved in a solvent (i.e. having solution viscosity of higher than 100 cp at 5% in NMP at room temperature) and dispersed nanoparticles of carbon of high specific surface areas (i.e. greater than 1 m2/g preferably greater than 10 m2/g), examples include but not limited to conductive carbon, carbon nanotubes, graphene, activated carbon or mixture thereof. This reticulated film composite exhibits high electrical conductivity (i.e. volume resistivity of less than 10,000 ?·cm) and superior dimensional stability even at elevated temperatures (i.e. at 140° C.).

  • Publication number: 20220306870
    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.).

  • Publication number: 20220298313
    Abstract: This invention discloses a reticulated film composite and a method of fabricating the reticulated film composite suitable as a separator in electrochemical cells as sound absorbing films, or as high efficiency filtering media. The reticulated film composite is produced by casting and drying of a slurry which exhibits a high yield stress (i.e. greater than 50 dyne/cm2) and comprised of a high MW resin dissolved in a solvent (i.e. having solution viscosity of higher than 100 cp at 5% in NMP or in water at room temperature) and dispersed nanoparticles with high specific surface areas (i.e. greater than 10 m2/g) such as fumed alumina, or fumed silica, or fumed zirconia or mixture thereof. This reticulated film composite exhibits superior cycling properties and high ionic conductivity with a porosity up to 80% while maintains a high dimensional stability (i.e. less than 10% shrinking) at elevated temperatures (up to 140° C.).

  • Patent number: 11248071
    Abstract: The invention relates to fluoropolymer filament for use in 3-D printing, and 3-D printed fluoropolymer articles having low warpage, excellent chemical resistance, excellent water resistance, flame resistance, and good mechanical integrity. Additionally, the articles of the invention have good shelf life without the need for special packaging. In particular, the invention relates to filament, 3-D printed polyvinylidene fluoride (PVDF) articles, and in particular material extrusion 3-D printing. The articles may be formed from PVDF homopolymers, copolymers, such as KYNAR® resins from Arkema, as well as polymer blends with appropriately defined low shear melt viscosity. The PVDF may optionally be a filled PVDF formulation. The physical properties of the 3-D printed articles can be maximized and warpage minimized by optimizing processing parameters.

  • Publication number: 20060189708
    Abstract: This invention relates to polymers for self-polishing marine antifouling coatings. More particularly, the invention relates to polymer binders, which provide an erosion rate in seawater that is suitable for use in marine antifouling coatings. These polymer binders contain pendant benzylsilylacrylate groups. Additionally it was found that marine antifouling coatings could be formed with lower silyl acrylate levels using the monomers of the invention, and still achieve a suitable erosion rate in seawater.

  • Publication number: 20050256235
    Abstract: The present invention relates to environmentally sensitive organic binders stabilized by maleic anhydride and its derivatives. The unstabilized binders can rapidly hydrolyze and thicken when exposed to the environment, and especially to moisture. Maleic anhydride and its derivatives act to stabilize these binders. The stabilized organic binders of the invention are especially useful for forming marine antifoulant coatings.

  • Publication number: 20050255081
    Abstract: The present invention relates to triorgano phosphites, triorgano amines, heteroaromatic nitrogen compounds, and carbodiimides used as stabilizers for hydrolyzable organic binders. The stabilizers help to prevent viscosity thickening of polymeric binders containing carboxylic ester groups. Without stabilization, the binders can rapidly thicken when exposed to moisture air. The stabilized organic binders of the invention are especially useful for formulating marine antifoulant coatings.
