▎ 摘　　要

NOVELTY - An electrolyte solution for electrodeposition is prepared by dispersing nanoparticles in an aqueous solution comprising a surfactant to form a dispersion of nanoparticle-surfactant micellar complexes in solution; and adding electrolytes comprising ionic metal. Concentration of surfactant is selected to substantially prevent sedimentation of the nanoparticles. USE - Preparation of electrolyte solution for electrodeposition for fabricating a permanent self-lubricating high-performance micro/nanostructured mold from two-dimensional (2D) material-reinforced metal nanocomposite using an electroforming process (claimed). Can be used for fabricating precision molded plastic parts for microfluidic or optical applications. ADVANTAGE - The method enables to prepare electrolyte solution for electrodeposition of nanoparticles in aqueous solution, which prevents sedimentation of the nanoparticles, and improves the mechanical properties of a material that comprises nanoparticles. The nanoparticles have interesting mechanical and tribological properties and can be used to modify the properties of the material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) manufacture of a component which involves preparing the electrolyte solution and electrodepositing a metal component from the electrolyte solution; (2) component formed using the electrolyte solution; and (3) fabricating a permanent self-lubricating high-performance micro/nanostructured mold from a two-dimensional (2D) material-reinforced metal nanocomposite using an electroforming process, which involves preparing an aqueous dispersion of self-assembled surfactants and 2D materials via ultrasonic or high-speed shear agitation, preparing a plating bath by mixing the aqueous dispersion of self-assembled surfactants and 2D materials with a metal or metal-alloy electroforming solution and further dispersing the 2D materials for homogeneous distribution via ultrasonic agitation, and putting a micro/nano structured cathode master obtained from a lithography, electroplating, and molding (LIGA) or UV-LIGA process and an anode into the plating bath and imposing a current between the cathode master and the anode, to electroform the high-performance micro/nanostructured mold on the cathode master.
