摘要:
Devices produced by patterning electroless metals on a substrate are presented. An active catalyst layer on the substrate is covered with a patterned mask and treated with a deactivating chemical reagent, which deactivates the catalyst layer not covered by the mask. Once the patterned mask is removed, the electroless metal layer can be placed to have a patterned electroless metals. Alternatively, a substrate can be coated with a blocking reagent in a pattern first to inhibit formation of the catalyst layer before a catalyst layer can be placed over the blocking agent layer and then electroless metal layer is placed on the catalyst layer. The pattern of the blocking reagent acts as a negative pattern of the final conductive line pattern.

A method for forming a flexible transparent conductive film includes steps of: (a) electrospinning a first solution, which contains a polymer, a solvent and a metal ion-containing precursor, to form an polymeric fiber onto a soluble substrate; (b) providing energy to reduce the metal ion-containing precursor of the polymeric fiber, so as to form metal seeds on the polymeric fiber; and (c) placing the polymeric fiber together with the soluble substrate into a second solution, such that the soluble substrate dissolves in the second solution to form an electroless-plating bath and such that the polymeric fiber is subjected to electroless plating to form a metal coating from the metal seeds.
摘要:
A conductive pattern is formed in a polymeric layer that has (a) a reactive polymer comprising pendant tertiary alkyl ester groups, (b) a compound that provides an acid upon exposure to radiation, and (c) a crosslinking agent. The polymeric layer is patternwise exposed to radiation to provide a polymeric layer comprising non-exposed regions and exposed regions comprising a polymer comprising carboxylic acid groups. The exposed regions are contacted with electroless seed metal ions to form a pattern of electroless seed metal ions. This pattern of electroless seed metal ions can be contacted with a non-reducing reagent that reacts with the electroless seed metal ions to form an electroless seed metal compound that has a pKsp of less than 40. This bound electroless seed metal compound is then electrolessly plated with a suitable conductive metal.
摘要:
A method is provided for metallization of substrates providing a high adhesion of the deposited metal to the substrate material and thereby forming a durable bond. The method applies novel adhesion promoting agents comprising nanometer-sized particles prior to metallization. The particles have at least one attachment group bearing a functional chemical group suitable for binding to the substrate.

A system or apparatus for forming a conductive pattern on a substrate (208) includes a thermal imaging head (220) that forms an image pattern on the substrate. A functional material (240) spraying element (224) applies a functional material on the substrate which bonds with the image pattern. The spraying element is integrated in the thermal imaging head. An electro-less deposition element is applied using the electro-less deposition element on the substrate to enhance the functionality of the final product.
摘要:
A resin board that consists of at least one of a mixture of a plurality of types of resins having different degrees of susceptibility to erosion by an ozone solution, and a resin having, in a molecule, a plurality of types of components having different degrees of susceptibility to erosion by the ozone solution is treated with ozone water to form a reformed layer, and a catalyst metal is adsorbed by the reformed layer so as to form a resin-metal composite layer, on which a plating process is performed. In the resin board, a component or components that is/are likely to be eroded on by the ozone solution dissolves into the ozone solution, and pores or clearances on the order of nanometers are formed between the component(s) and a component or components that is/are less likely to be eroded by the ozone solution. With the plating deposited in the pores or clearances, the adhesion strength is improved due to an anchoring effect. Thus, the adhesion strength of the plating film is improved even where the resin-metal composite layer has a thickness of 10 to 200 nm.

A process for electroless silver plating of a work piece includes simultaneously spraying a silver nitrate solution and a reducer on a work piece to form a reflective layer on the work piece, applying a water-based urethane coating on the reflective layer, and applying either a top coat that is solvent based or a powder based on the water-based urethane coating.
