Friction nano-generator based on three-dimensional spacer fabric and preparation method thereof

The invention relates to a three-dimensional spacer fabric-based friction nano-generator and a preparation method thereof, and belongs to the technical field of textiles. The friction nanometer generator based on the three-dimensional spacer fabric comprises the three-dimensional spacer fabric, one side of the three-dimensional spacer fabric adopts an electrodeless chemical plating method to enable the fiber surface of the fabric to be coated with a conductive metal layer, and the conductive metal layer is coated with a friction medium layer; the conductive metal is one or more of copper, nickel and silver. The friction nano-generator based on the three-dimensional spacer fabric is a common electrode breathable friction nano-generator based on a warp knitting fabric structure, copper-plated electrodes of two devices which are both in a single-electrode mode are shared by utilizing an original fabric structure, procedures are reduced, and the electrode machining cost and the structure construction cost are red
