A resin-rubber composite in which a polyamide-based resin-molded product or a polyphenylene sulfide-based resin-molded product is directly vulcanization-bonded to a peroxide-crosslinkable nonpolar rubber composition, which forms a rubber layer, without interposing an adhesive, wherein both resin-molded products have a polymerized film with a radical, which is formed by activating the surface of the product, in the case of polyamide-based resin-molded products, by low-pressure plasma treatment by a microwave method using inert gas, or by activating the surface of the product, in the case of polyphenylene sulfide-based resin-molded products, by low-pressure plasma treatment by a microwave method using active gas, and then performing low-pressure plasma treatment by a microwave method using a hydrocarbon-based monomer in both cases. The resin-rubber composite can be effectively used for drum seals, automobile parts such as side cover seals for transmissions, anti-vibration rubber, resin rubber laminate hoses, and the like.

A resin sheet attaching method of attaching a resin sheet to a workpiece. The resin sheet attaching method includes a molecular weight reducing step of applying vacuum ultraviolet radiation to the front side of the resin sheet, thereby cutting an intermolecular bond in a surface region having a depth of tens of nanometers from the front side of the resin sheet to thereby reduce the molecular weight of the surface region and produce an adhesive force, and a resin sheet attaching step of attaching the front side of the resin sheet to the workpiece after performing the molecular weight reducing step.

A process for enhancing the gas barrier properties of a composite laminate material whilst maintaining adequate bond strength, in which a gas barrier coating comprising a clay dispersion and a polymer solution or dispersion is positioned between two flexible plastics films using an adhesive, wherein a coating is applied to a first flexible polymer film at a coating weight (D), an adhesive is applied to either or both of the coated side of the first film or to a second polymer film and adhering the first and second films together to provide a material in which: (A/B). (C/D)>200, and in which: A/B>75; C>1.0; and D<1.5; wherein: A=Oxygen Transmission Rate for the laminate at 23 0C and 50% RH without the coating; B=Oxygen Transmission Rate for the laminate at 23 0C and 50% RH with the coating; C=Bond Strength in N/15 mm after the adhesive has fully cured; D=Coating Weight in g/m.sup.2 (dry).

Adhesive tape having at least two layers A and B laminated directly on one another, with at least one or both layers A or B being an adhesive, and the interfaces of the layers A and B laminated on one another being subjected to a physical method, the physical method being selected from the group consisting of corona discharge, dielectric barrier discharge, flame pretreatment and plasma treatment, before the layers are laminated to one another, with the two methods differing from one another.

In various aspects, the disclosure relates to methods of adhering a liquid metal composite to a substrate. The method can include applying a pretreatment to a surface of the substrate to form an activated surface. In some aspects, the pretreatment is an oxygen plasma treatment. The methods can then include contacting a silane with the activated surface to form a functionalized surface. A variety of suitable silanes may be used, but in some instances the silane is aminopropyltriethoxysilane (APTES). The method then includes contacting the functionalized surface with a liquid metal composite precursor and curing the liquid metal composite precursor while in contact with the functionalized surface to form the liquid metal composite adhered to the substrate. Articles made by the methods are also provided, including articles such as electronics having the liquid metal composite adhered to a substrate using the methods described herein.
