Abstract

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.

Description

technical field [0001] The invention belongs to the field of micro-nano science and technology, in particular to a roll-to-roll method for preparing a large-area micro-nano structure generator film. Background technique [0002] Micro-nano generator is a small-volume, high-power micro-energy device that has developed rapidly in recent years. It can collect tiny vibrational mechanical energy in the surrounding environment and convert it into electrical energy to power other nano-devices, such as sensors and detectors. Provide energy. The invention of micro-nano generators not only brings the possibility of miniaturization of energy systems, but more importantly, for the realization of nano or microelectronic devices that are completely wireless, bio-implantable, and unattended for a long period of time or even for a lifetime, micro-nano Generators provide an ideal power system. [0003] At present, the preparation method of the micro-nano structure generator film is the sil...
