A method of producing a film-attached resin base may include supplying a surface treatment gas including at least fluorine gas to a resin base including reinforcing fibers so that embrittled regions are formed in a surface of the resin base and the reinforcing fiber present near the surface of the resin base is modified at least partially; removing at least the embrittled regions so that an uneven surface is formed on the resin base and the reinforcing fiber is at least partially exposed in the uneven surface; and forming a film onto the uneven surface of the resin base.

The present invention relates to a composition in the form of sheet or layer comprising a layer of an aromatic polymer and a layer of metal adhering to at least one side of said polymeric sheet, and to its uses.

Proposed is a mobile device case that accommodates or covers a substrate and an electronic element located on the substrate. The case includes: a case frame made of a high molecular material including a resin and having a cover part for accommodating or covering the substrate and protrusions protruding from the cover part in such a manner as to be extended close to the electronic element; and a metal coating layer formed by coating a metal on a surface of the case frame including the protrusions to improve electromagnetic shielding ability.

A coating method for preventing outgassing from an aerospace component made of a resin is proposed. In the coating method for preventing outgassing from the aerospace component, first, a polymer including a resin is provided. After that, primary outgassing in which the polymer is subjected to hot air drying to evaporate gas therefrom is performed. Next, the surface of the polymer after the primary outgassing is subjected to a cold plasma treatment to introduce hydrophilic functional groups so that it is possible to perform plating on the surface of the polymer. After that, the surface of the polymer after the cold plasma treatment is subjected to a catalytic treatment and an activation treatment for post-processes. Next, a first functional metal layer is formed on the surface of the polymer by means of electroless plating to suppress the release of gas through outgassing.

A method for applying a metal on a substrate comprises: a) applying a coating by treatment in a plasma, comprising a compound selected from alkanes up to 10 carbon atoms, and unsaturated monomers, and b1) producing polymers on the surface of the substrate, the polymers comprising carboxylic groups and adsorbed ions of a second metal, reducing the ions to the second metal, or alternatively b2) producing polymers on the surface, bringing the surface of the substrate in contact with a dispersion of colloidal metal particles of at least one second metal, and c) depositing the first metal on the second metal. Advantages include that materials sensitive to, for instance, low pH or solvents can be coated. Substrates including glass, SiO.sub.2 with very few or no abstractable hydrogen atoms as well as polymer materials containing halogen atoms can be coated with good adhesion.

A linear shape member is composed of a linear shape electrical insulating body comprising irregularities on a surface, and a plating layer coating the surface of the electrical insulating body. An average irregularities spacing Sm of the irregularities is not more than 20.0 m.

An electroless process for depositing gold (Au.sup.0) from a solution, comprising allowing gold (Au.sup.0) place from a solution of gold thiocyanate complex dissolved in a mixture of water-miscible organic solvent and water, or the deposition of gold (Au.sup.0) takes place on a deposition-directing layer comprising positively charged organic groups, said layer being provided on at least a portion of a surface of a substrate sought to be gold-coated.

A method for application of a metal on a substrate comprises a) contacting at least a part of the surface of the substrate with at least one initiator, and polymerizable units with the ability to undergo a chemical reaction to form a polymer, the polymer comprising at least one charged group, wherein the contacting is achieved by contacting a pad with a plate comprising the at least one initiator and the polymerizable units and subsequently contacting the pad with the surface of the substrate, thereby transferring the at least one initiator and the polymerizable units to the surface of the substrate. Subsequently a metal layer is produced on the surface. The compactness of the applied metal layer is increased.

Aqueous dispersions of artificially synthesized, mussel-inspired polydopamine nanoparticles were inkjet printed on flexible polyethylene terephthalate (PET) substrates. Narrow line patterns (4 m in width) of polydopamine resulted due to evaporatively driven transport (coffee ring effect). The printed patterns were metallized via a site-selective Cu electroless plating process at a controlled temperature (30 C.) for varied bath times. The lowest electrical resistivity value of the plated Cu lines was about 6 times greater than the bulk resistivity of Cu. This process presents an industrially viable way to fabricate Cu conductive fine patterns for flexible electronics at low temperature, and low cost.
