A method for metallizing plastic by pre-plating for electroplating, forming a metal bonding layer and a metal transition layer using electro arc ion plating or magnetron sputtering in series, and then forming a metal conductive layer on the metal transition layer using the electro arc ion plating. At least forming the metal conductive layer comprises: disposing a magnetic filter device between a metal target and a vacuum chamber in which the plastic workpiece is placed, so that positively charged metal ions generated by the metal target are deflected by the magnetic filter device and then enter the vacuum chamber to be deposited on the surface of the plastic workpiece.

Provided are chrome-free adhesion pretreatment processes for use on a variety of reinforced or unreinforced plastics and polymers, such as polyimides, polyetherimides and polyvinylchloride. The pretreatment process can be performed in a combination of two sequential operations, which includes treating with a first solution containing nitric acid and subsequently treating with a second solution that includes sulfuric acid and periodate ions. Alternatively, the pretreatment process can be performed by treatment with a single combined composition that includes nitric acid, sulfuric acid, and periodate ions. The pretreatment processes, either done in two separate solutions, sequentially, or in one combined solution, produce an adherent surface for further metallization of the article, with adhesional values of the metal layer higher than those achieved using conventional chromic acid pretreatment processes.

A coated substrate includes a substrate, a zirconium-containing layer disposed over the substrate, and one or more copper alloy layers disposed over the substrate. Variations include coated substrate with a single copper alloy layer, alternating copper layers, or a combined copper alloy/zirconium-containing layer.

A film and a manufacturing process thereof, including a base layer, where each of front and back sides of the base layer is provided with a bonding layer, a functional layer, and a protective layer in sequence; the functional layer is composed of a first composite copper layer and/or a second composite copper layer; the first composite copper layer is formed by repeating copper coating on a surface of the bonding layer 2 to 500 times; and the second composite copper layer is formed by repeating copper coating on a surface of the bonding layer 2 to 500 times. The film has low cost, simple process, and prominent appearance performance, and the present disclosure belongs to the technical field of energy storage unit materials.

An article is provided. The article includes an acrylate layer; a substrate overlaying the acrylate layer; and an adhesive layer between the acrylate layer and the substrate, wherein the adhesive layer includes germanium; wherein a release value between the acrylate layer and the adhesive layer is more than 200 g/inch.

The present disclosure relates to an antiviral thin film layer that may include a metallic material. The antiviral thin film layer may have a VLT of at least about 60%. The antiviral thin film layer may further have an influenza A subtype H1N1 antiviral rating (H1N1 antiviral rating) of not greater than about 360 minutes, where the H1N1 antiviral rating is defined as the amount of time required for H1N1 viral activity on a surface of the metallic layer to drop from an initial test concentration placed on the surface of the thin film layer to less than 25.0% of the initial concentration placed on the surface as measured using ISO21702.

Provided is a method for preparing a carbon nanotube/polymer composite material, including: coating a nano-silicon oxide film on the surface of a porous polymer by vacuum coating; depositing a metal catalyst nano-film on the nano-silicon oxide film by vacuum sputtering; growing a carbon nanotube array in situ on the surface of the porous polymer by plasma enhanced chemical vapor deposition to obtain a carbon nanotube/polymer porous material; and impregnating the carbon nanotube/polymer porous material with a polymer and curing to obtain the carbon nanotube/polymer composite material. By using a heat-resistant polymer having a high heat-resistant temperature and a PECVD technique, a carbon nanotube array directly grows in situ on the surface of a polymer at a low temperature, which thereby overcomes the defects of the composites previously prepared, in which carbon nanotubes are difficult to be homogeneously dispersed and the interfacial bonding force in the composites is weak.
