A sheet material includes a resin layer containing a binder and polypyrrole particles, an electroless plating film provided on the side of one main surface of the resin layer and including first electroless plating films and a second electroless plating film, and a transparent base material provided on the side of the other main surface of the resin layer.

Electroless underwater metal plating of a surface of fixed or floating structure is accomplished by transferring to the surface metal ions from a metal precursor in a solid or semisolid electrolyte that is pressed against and moved over a submerged surface. Metal ions from a metal salt blended in the solid or semisolid material plate the underwater substrate.

An anisotropic conductive sheet has an insulation layer having a plurality of through-holes and a plurality of conductive layers each arranged on an inner wall surface of each of the plurality of through-holes. Each of the conductive layers has a base layer arranged on the inner wall surface of each of the through-holes and a metal plating layer arranged so as to contact with metal nanoparticles or a metal thin film in the base layer or the metal thin film. The base layer includes metal nanoparticles or a metal thin film and a binder, wherein at least a portion of the binder is arranged between the inner wall of each of the through-holes and the metal nanoparticles or the metal thin film. The binder is a sulfur-containing compound having a thiol group, a sulfide group or a disulfide group.

The disclosure provides a Sn—In electroplating bath that is Pb-free, environmentally safe, operates at room temperature, and does not require changes in existing plating assemblies. Room temperature aging and limited thermal cycling tests show that the electroplated Sn—In alloy film on a Cu substrate effectively mitigates whisker growth.

A method for making a conductive film includes the steps of: depositing a conductive metal film on a substrate to form a metal-coated substrate; depositing a fiber pattern on the conductive metal film of the metal-coated substrate to form a masked substrate, the fiber pattern defining protected metal and exposed metal of the conductive metal film; removing the exposed metal from the conductive metal film of the masked substrate to form a protected conductive film; and removing the fiber pattern from the protected conductive film to expose the protected metal and provide a metal pattern on the substrate. An annealing step con be employed after depositing the fiber pattern to increase the surface area of contact between the fiber pattern and the conductive metal film.
