A method for surface treatment of a silicone rubber includes: providing the silicone rubber bearing a polar group on a surface of the silicone rubber, and applying a multifunctional compound to the surface of the silicone rubber bearing the polar group to allow the multifunctional compound to react with the polar group to form a coating.

A process for fabricating a thermochromic film is disclosed which includes the steps of dispersing a predetermined amount of vanadium dioxide (VO.sub.2) nanoparticles in a predetermined amount of poly(methyl methacrylate) (PMMA), stirring a mixture thereof for a first predetermined amount of time, generating cross-links to molecule chains of the PMMA in the mixture, and blade coating a predetermined thickness of the cross-linked mixture on a substrate to form the thermochromic film.

Modified plastic surfaces with perfluoropolymers are provided, whereby plastic surfaces that are intended for use under tribological conditions have substantially improved assembly properties and/or sliding friction properties and exhibit a very low degree of wear. Accordingly, modified plastic surfaces with perfluoropolymers are provided in which modified perfluoropolymer (micro)powders are present at the surface of plastics that comprise olefinically unsaturated double bonds at least at the surface such that the modified perfluoropolymer (micro)powders are chemically covalently bonded via a radical coupling of the olefinically unsaturated double bonds with perfluoropolymer (peroxy) radicals of the modified perfluoropolymer (micro)powders after a reactive conversion under mechanical stress at room temperature.

Disclosed are laminates comprising a carbon fiber reinforced polymer sheet and a layer of polysilazane and methods for producing such laminates.

The present disclosure provides packaging materials and products including such as a multilayer structure comprising a base (X), a layer (Y), and a layer (Z), in which the layer (Y) and the layer (Z) are adjacently stacked in at least one pair of the layer (Y) and the layer (Z).

Disclosed is a resinous adhesion promoter comprising (a) a random copolymer having first and second constitutional monomeric units, the first units comprising halogen and/or a pendant organic group having six or more carbon atoms and the second monomeric units comprising an active hydrogen-containing functional group; and (b) one of either (i) a non-reactive adhesion promoter or (ii) a reaction mixture comprising a first component and a second component, at least one of the first and second components having functional groups being reactive with the active hydrogen-containing functional groups of the random copolymer.

A cartilage mimetic gel includes double network hydrogels. The double network hydrogels comprise a first crosslinked network and a second crosslinked network. The first crosslinked network can be formed from poly(2-acrylamido-2-methylpropane sulfonic acid). The second crosslinked network can be formed from poly(N-isopropyl acrylamide-co-acrylamide).

A moisture barrier laminated film (10) includes: a plastic film (A) having an inorganic barrier layer (A1); a moisture trapping layer (B) containing an alkali component; and a coating layer (C) provided between the inorganic barrier layer (A1) and the moisture trapping layer (B). In the coating layer (C), a moisture permeability at 40° C. and 90%RH is 6.0 × 10.sup.4 g/m.sup.2/day or less, and a storage modulus E′ (at 2π rad/s) in viscoelasticity measurement at 85° C. is 30 MPa or more.
