Abstract

The invention discloses an efficient preparation method for a flexible ultra-extension conductive thin film based on a one-dimensional nano material, and belongs to the technical field of nano photoelectric materials. The preparation method comprises the steps of firstly, evenly spraying a one-dimensional nano conductive material solution on a hard substrate so as to prepare a conductive thin film; secondly, evenly spinning an uncured PDMS colloid at the surface of the conductive thin film, then placing a stretched cured PDMS film at the surface of an uncured PDMS film, and finally applying great pressure and placing the film in a vacuum drying oven so as to be cured. The preparation method provided by the invention for the flexible ultra-extension conductive thin film is simple in operation, low in cost and wide in application range. The preparation method has the characteristics of efficient transfer process and large-area preparation. The prepared conductive thin film shows prominent advantages of flexible ultra-extension and stable electrical performance.
