Abstract: Multilayer barrier films and methods of making the films are provided. The films include a smooth layer and a barrier layer directly disposed on the smooth layer. In some cases, the smooth layer includes a thiol-ene material as a polymeric matrix material. In some cases, the films have a sandwich structure of barrier layer/smooth layer/substrate/smooth layer/barrier layer.

Abstract: The present invention provides a pressure-sensitive adhesive composition, including: an acrylic copolymer and a crosslinking agent. The acrylic copolymer is a reaction product of a mixture of the following monomers: a first alkyl (meth)acrylate, an alkyl group in the first alkyl (meth)acrylate having at least 6 carbon atoms; a second alkyl (meth)acrylate, an alkyl group in the second alkyl (meth)acrylate having 1 to 5 carbon atoms; and a vinyl carboxylic acid, the weight ratio of the vinyl carboxylic acid to the mixture being 4% to 5%. The crosslinking agent is an organometallic chelating agent. The weight ratio of the organometallic chelating agent to the mixture is 0.05% to 0.25%. The pressure-sensitive adhesive composition does not contain an effective amount of a tackifier. The present invention further provides a pressure-sensitive adhesive solution, a pressure-sensitive adhesive tape, and a method for preparing the same. The pressure-sensitive adhesive of the present invention is a removable pressure-sensitive adhesive, and is applicable in hot weather and cold weather, and the adhesiveness of the pressure-sensitive adhesive does not decrease over time.

Abstract: The present invention provides a two-component thermally conductive adhesive composition and a two-component thermally conductive gap-filling glue. The composition comprises: 8-38 wt % of an acrylate monomer or a combination of an acrylate monomer and an acrylate oligomer, with a glass transition temperature ranging from −80° C. to −10° C.: 0.2-4 wt % of a peroxide oxidant: 0.05-1 wt % of a peroxide decomposition promoter; and 60-90 wt % of a thermally conductive filler, wherein the two-component thermally conductive adhesive composition comprises Part A and Part B. Part A comprises a peroxide oxidant and Part B comprises a peroxide decomposition promoter: the acrylate monomer, or the combination of the acrylate monomer and the acrylate oligomer, and the thermally conductive filler exist in one or both of Part A and Part B. The products of the two-component thermally conductive adhesive composition and the two-component thermally conductive gap-filling glue after curing have a high elongation-at-break, high thermal conductivity and low bonding strength to aluminum metal surfaces, and are suitable for use as a thermally conductive gap-filling material in the battery pack module of an electro-mobile.
