An object is to coat a target position on a substrate with a dense film. In order to achieve the object, while a substrate on which a base containing a coating material is formed is transported, an auxiliary agent is applied to the substrate, and then a main agent containing a coating material is applied to the substrate to react the main agent with the auxiliary agent, so that a portion on the substrate where the base is formed is coated with the coating material.

The present invention discloses a novel activator system for electroless metallization deposition, particularly activators that may be free of tin, binders and reducing agents. Activators of the invention are preferably employed for electroless copper deposition.

A method for forming a nickel plated graphene hollow sphere is based on self assembly of graphene under the actions of a rotation force and the van der Waals force, and an electroless nickel plating process performed on the exposed surface of the graphene by means of a hydrothermal method. The method is simple to implement at low cost, and the nickel plated graphene hollow sphere product can be produced with good reproducibility and a high yield. The nickel plated graphene hollow sphere formed by the present method can exhibit good electromagnetic wave absorbing performances of both nickel and graphene, and may have a lower overall density.

Additive manufacturing processes, such as powder bed fusion of thermoplastic particulates, may be employed to form printed objects in a range of shapes. It is sometimes desirable to form conductive traces upon the surface of printed objects. Conductive traces and similar features may be introduced during additive manufacturing processes by incorporating a metal precursor in a thermoplastic printing composition, converting a portion of the metal precursor to discontinuous metal islands using laser irradiation, and performing electroless plating. Suitable printing compositions may comprise a plurality of thermoplastic particulates comprising a thermoplastic polymer, a metal precursor admixed with the thermoplastic polymer, and optionally a plurality of nanoparticles disposed upon an outer surface of each of the thermoplastic particulates, wherein the metal precursor is activatable to form metal islands upon exposure to laser irradiation. Melt emulsification may be used to form the thermoplastic particulates.
