Method of reel-to-reel preparation of large-area micro-nano structured generator membrane

The invention provides a method of reel-to-reel preparation of large-area micro-nano structured generator membranes, and solves problems such as complex process and limited size of product area in methods for preparing micro-nano structured generator membranes in the prior art. The method comprises firstly mixing carbon nano tubes and piezoelectric particles in proportion to liquid PDMS to form a plastic polymer, then placing the plastic polymer in an impression apparatus and impressing the plastic polymer through steps of initial molding, impressing and solidifying and shaping to obtain a micro-nano concave and convex structure, and finally sputtering electrodes on the plastic polymer to obtain the micro-nano structured generator membrane. The method is simple in process and low in cost, has good repeatability, can help to rapidly prepare the large-scale flexible membrane material having uniform thickness and components in batches. The method lays foundations for integration, large-scale production and commercialization of micro-power, development of new energy, and reuse of renewable energy.
