Nanoporous composite separators are disclosed for use in batteries and capacitors comprising a nanoporous inorganic material and an organic polymer material. The inorganic material may comprise Al.sub.2O.sub.3, AlO(OH) or boehmite, AlN, BN, SiN, ZnO, ZrO.sub.2, SiO.sub.2, or combinations thereof. The nanoporous composite separator may have a porosity of between 35-50%. The average pore size of the nanoporous composite separator may be between 10-90 nm. The separator may be formed by coating a substrate with a dispersion including the inorganic material, organic material, and a solvent. Once dried, the coating may be removed from the substrate, thus forming the nanoporous composite separator. A nanoporous composite separator may provide increased thermal conductivity and dimensional stability at temperatures above 200° C. compared to polyolefin separators.

A method for applying a polymer coating to a substrate wherein the resultant layer of polymer on the substrate has a substantial thickness. A mixture of polymer material, including reactor bead polymer and ground polymer, may be used in a powder coating process to achieve thicker polymer layers. In separate embodiments, the resultant polymer layer may remain on the substrate or may be removed from the substrate.

The present invention relates to a method of preparing reduced graphene oxide, incorporation of the reduced graphene oxide into polyisoprene latex to provide a polyisoprene latex graphene composite and elastomeric articles prepared using the polyisoprene latex-graphene composite. In particular, the reduction of graphene oxide is accomplished without the use of strong reducing agents and organic solvents and incorporation of the reduced graphene oxide into polyisoprene latex is accomplished using room temperature latex mixing method or hot maturation. The resultant composite exhibits good colloid stability, and polyisoprene latex films produced the composite exhibit good mechanical properties with improved ageing resistance.

A method for preparing an intelligent antibacterial and antioxidative film involves preparing a PVA solution; adding nano-TiO.sub.2 to the PVA solution to obtain a PVA-TiO.sub.2 solution; determining the optimal amount of nano-TiO.sub.2; preparing a PSPC solution; preparing a PSPC-TiO.sub.2-PVA solution; and producing a PSPC/TiO.sub.2/PVA film. The film has better mechanical performance than saccharide and protein films. Shelf life of food is prolonged as the film possesses antibacterial and antioxidative properties. Furthermore, the film shows different colors in various pH environments. The film has a wide range of applications in food packaging owing to the integration of color development and antibacterial and antioxidative properties.

Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.

A shoe cover is a natural latex article with reduced amount of sulfur cross linking agent and accelerators including zinc dithiocarbamate that break catalytically soluble sulfur S.sub.8 sulfur rings forming sulfur linear chains. Surfactants present in the pre-vulcanization composition wets natural polyisoprene particles and permeates small sized sulfur into the interior of these particles thereby pre-vulcanizing the particles. The latex emulsion also has post-vulcanization composition with accelerators that crosslink between particles during the post vulcanization cure cycle. The dipped natural polyisoprene article is substantially uniformly cured both in the inter-particle and intra-particle regions and reliably exhibits high cross link density, uniform distribution of double bonds and zinc segregation at the boundaries or original particles. The natural rubber films exhibit high tensile strength, tensile modulus, tear strength, elongation with low modulus of the shoe cover. The bottom surface of the shoe cover is etched to produce a slip resistant surface.
