The present invention relates to the use of a fluorinated copolymer in the manufacture of a solid polymer film, to give said film properties of adhesion to a metal surface or to glass. It also relates to a process for improving the adhesion of a fluoropolymer to a metal, polymer or glassy substrate, and also to a composite part comprising a solid polymer film in direct contact with at least one metal or glassy element.

Systems, methods, and devices of the various embodiments provide for the creation of holey graphene meshes (HGMs) and composite articles including HGMs. Various embodiments provide solvent-free methods for creating arrays of holes on holey graphene-based articles formed from dry compression (such as films, discs, pellets), thereby resulting in a HGM. In further embodiments, a HGM can used as part of a composite, such as by: 1) embedding a HGM into another matrix material such as carbon, polymer, metals, metal oxides, etc; and/or (2) the HGM serving as a matrix by filling the holes of the HGM or functionalizing the HGM body with another one or more materials. In various embodiments, HGM can also be made as a composite itself by creating holes on dry-compressed articles pre-embedded with one or more other materials.

The present invention relates to a roll construction of laminated material that inhibits delamination of the polymer layer from a backer film upon unwinding of the roll construction. Particularly, aspects of the present invention are directed to a roll construction of laminated material prepared by a process that includes providing the laminated material having an ion-exchange resin layer, a release film, and a base layer, and feeding the laminated material to a roller to generate the roll of the laminated material. The laminated material is fed to the roller such that a first layer of the laminated material wound around the core includes the inner surface of the base layer of the first layer contacting an outer surface of the core.

Disclosed are a method for a preparing fluorine- and chlorine-containing conductive polymer resin, a single-side or double-side filled composite film prepared using the fluorine- and chlorine-containing conductive polymer resin, and a method for preparing the film. The fluorine- and chlorine-containing conductive polymer single-side or double-side filled composite film comprises a microporous film skeleton and the fluorine- and a chlorine-containing conductive polymer resin. The composite film is mechanically stronger, more waterproof, more impervious to water and toxic and harmful chemicals, and more moisture permeability. When applied to biochemical protective clothing, it can greatly enhance the combat effectiveness of the soldiers because it is light and more impervious to water and toxic and harmful chemicals, brings about comfort, and keeps the soldiers warm. When applied to fuel cells, it can provide better electrical properties due to its high conductivity and can allow the fuel, such as hydrogen or alcohol, to burn more completely.
