The present invention relates to the development and fabrication of thin-film polymer composite materials containing vertically aligned nanopores. The present invention provides methods of aligning nanopores in a polymeric film. The present invention also provides composite materials and methods of fabricating composite materials containing vertically aligned nanopores.

The present invention concerns a method for coating a textile material with a silicone elastomer composition crosslinkable by condensation reactions, to produce a solid silicone elastomer, optionally in a thin layer, on a flexible support that can be made from a textile material, paper, polyvinyl chloride, polyester, polypropylene, polyamide, polyethylene, polyurethane, non-woven glass fiber fabric or polyethylene terephthalate.

A population of nanocomposite particles including nanoparticles and poly (ethylene imine) (PEI) grafted thereto. In some embodiments there is no intervening layer between the nanoparticles and the PEI. Methods of making and using nanocomposite particles are also disclosed.

Self-healable, omniphobic coatings and related methods are provided. In embodiments, a self-healable, omniphobic coating comprises a matrix of crosslinked, entangled hydrogel polymers, the hydrogel polymers comprising hydroxyl (OH) groups, hydroxyl group precursors, or both, and nanoparticles distributed throughout the matrix; and fluorinated silane molecules covalently bound to the matrix.

The present application provides an oven drying apparatus and a coating device. The oven drying apparatus comprises an oven drying chamber and a heating assembly. The oven drying chamber is equipped with a first oven drying side having a plurality of first air inlet portions for fluid medium to enter the oven drying chamber. The heating assembly is disposed on the first oven drying side. The first oven drying side is further provided with at least one air return portion provided between two adjacent first air inlet portions, and the air return portion being configured for fluid medium in the oven drying chamber to be discharged from the oven drying chamber. The arrangement of an air return portion between two first air inlet portions can discharge fluid medium between the two first air inlet portions and take away the heat, thus avoiding accumulation of heat between the two first air inlet portions.

Methods for producing layered structures that include a conductive polymeric layer and a dielectric polymeric layer. The dielectric polymeric layer can be formed by curing a first volume of a dielectric polymeric material. A second volume of the dielectric polymeric material is doped with conductive particulates to yield a conductive polymeric material, which is then partially cured and solvated to create a conductive polymeric paste. The paste is applied to a surface of the dielectric polymeric layer, dried, and cured to form a conductive polymeric layer on the pre-strained dielectric polymeric layer yielding a layered structure that includes the conductive polymeric layer and the dielectric polymeric layer. A pre-strain is induced in the dielectric polymeric material by contacting a chemical thereto that causes swelling therein.

Provided is an antifouling sheet having an antifouling layer formed of an antifouling layer-forming composition containing a specific tetrafunctional silane compound (A) and a specific trifunctional silane compound (B) wherein the content of the component (B) is 8 to 90 mol % relative to 100 mol % of the component (A), and the antifouling layer is a layer formed by drying and curing a coating film formed of the antifouling layer-forming composition, in an ammonia atmosphere. Also provided is a method for producing the antifouling sheet. The antifouling sheet is provided with an antifouling layer having good surface state and curability, has a large slip acceleration for water droppings, thereby having excellent water repellency that makes water droplets slip off instantly, and has excellent interlayer adhesiveness.
