“…It should be noted that alkaline (usually at higher PH) chemical metal deposition gave crystalline nickel which contained no or a very small amount of phosphorus. 9 However, when the PH of the deposition solution decreased, the amount of phosphorus was changed (usually increased) and phosphorus was dispersed in the nickel phase, resulting a different structure, even an amorphous NiOP structure, thereby leading to a significant change in the magnetic properties. Since an amorphous Ni metal (or alloy) magnet has important potential applications, for example, as a soft magnet, the chemical metal deposition method provides a easy and feasible route to prepare such kinds of materials.…”

Poly(styrene-co-methacrylic acid) P(St-co-MAA) microspheres with a monodisperse size distribution were prepared by emulsifier-free emulsion copolymerization of St and MAA. The effects of MAA content on the polymerization rate and the content of MAA in the copolymer were investigated by gravimetrical and IR methods, respectively. The results of XPS measurement indicated the presence of a carboxyl functional group. By chemical metal deposition, nickel or palladium particles were formed and deposited on the surface of P(St-co-MAA) microspheres to form P(St-co-MAA)Ni or P(St-co-MAA)Pd composite particles. XRD measurement and TEM observation confirmed that nickel and palladium metal particles in a small size (20 -40 nm) were distributed on surface of the copolymer microspheres.

“…To enhance the electrical conductivity of parts moulded with Schulatec TinCo 50, an electroplating process was applied. The most widely used metallization process for plastics is an electroless process which is characterized by being a slow, chemical intensive process involving many different process steps [9]. The electroless process is toxic especially the etching solution that consists of a hot balanced mixture of chromic acid, sulfuric acid, and water [10].…”

Electrodeposition or electroplating is predominantly applied to metallic components. Electroplating of plastics is possible in some cases where an initial electroless plating layer of nickel or copper is made to provide a conductive surface on the plastic part. This paper proposes a method for direct electroplating of plastic eliminating the need for slow and expensive processes like electroless metal deposition, PVD coating, painting with conductive inks etc. The results obtained from the test demonstrate the potential of direct electroplating of plastic to enhance the electrical conductivity and the use of electroplated plastics for advanced applications like Moulded Interconnect Devices (MIDs).

“…Theory of Eiectroless Deposition. The formation of a continuous metallic film on a nonconductive plastic surface without the use of an electric current is called electroless plating (6,7). It can be defined as the controlled reduction of a solution of a metal ion by a dissolved reducing agent at a catalytic interface to give a coherent film.…”

Plastics can be coated with metals for decorative or functional purposes, or both. This article is broken down into four sections that are the four main techniques of metallizing: electroless plating, metal‐spraying, sputtering, and vacuum metallizing. The most important commercial process is electroless plating, which includes plating on plastics for automotive and decorative uses and the related technologies for printed circuits. Flame or arc spraying is mainly used for functional purposes such as radio‐frequency‐interference shielding. Sputtering and vacuum metallizing are widely used, often in continuous coating of plastic films where they are the predominant technologies. Other techniques such as metallic‐filled paints and hot stamping are also used. The beginning of these processes goes back 80–130 years, but many of these processes have only achieved commercial importance for coating of plastic materials relatively recently.

Electroless plating of plastics

Abstract: Electroless deposition of metals can be defined as the controlled autocatalytic reduction of a dissolved metal ion by a dissolved reducing agent at an interface to give a uniform film. The first electroless solutions were developed around 1840 for use in silver glass mirrors.
