Abstract

Hybrid particles having improved electrical conductivity and thermal and chemical stabilities are disclosed. The hybrid particles are for use in conductive pastes. The hybrid particles include a nanoparticle selected from a graphene-containing material, a dichalcogenide material, a conducting polymer, or a combination thereof encapsulated in a conducting metal. The hybrid particles include a nanoparticle selected from a graphene-containing material, a dichalcogenide material, or a combination thereof encapsulated in a conducting polymer, and optionally further in a conducting metal. Suitable conducting metals include nickel or silver. Suitable conducting polymers include polyaniline, polypyrrole, or polythiophene. Suitable dichalcogenide materials include MoSor MoSe. The hybrid particles can further include a conducting polymer layer on an outer surface of the conducting metal. Methods of making the hybrid particles are also disclosed.
