  • Bathless metal-composite electroplating
    Patent number: 11519091
    Abstract: A bathless plating for a conductive material with composite particles or with high surface coverage. The setup for the bathless electro-plating includes a cathode, a composite mixture, a membrane, and an anode. The cathode is a conductive material. The composite mixture comprises a metal salt, an acid, and a composite material. The composite mixture is applied to the cathode. A hydrophilic membrane is applied to the composite mixture. An anode, with oxidizing properties, is applied to the membrane. A current is applied to the bathless setup. Upon removing the current and composite mixture from the cathode, a metal-based composite coating remains on the cathode.
    Type: Grant
