NOVELTY - Catalyst-free electroless plating method involves preparing a plating composition comprising a reducing agent and at least one metal precursor chosen from nickel precursor, iron precursor, cobalt precursor and copper precursor, and introducing the composition to a solution containing to-be-plated component, so that the concentration of the metal precursor becomes 0.0001-0.0054 M. USE - Catalyst-free electroless plating of to-be-plated component e.g. graphene, carbon nanotubes, carbon black, carbon fibers, glass fibers, polymer fibers or porous carbon material (all claimed). ADVANTAGE - The method enables efficient and economical catalyst-free electroless plating by simple process without requiring expensive precious metal catalyst. The wettability of the to-be-plated component is improved. Since catalyst is not required, the electroless plating can be performed in a single step without catalyst pretreatment.
