Abstract

The invention discloses a preparation method of a flexible transparent conductive nanometer thin film. The method comprises the steps of preparing a cellulose template firstly; next, performing firstimpregnation liquid pretreatment, transparent treatment, drying treatment, hot pressing treatment and secondary transparent treatment in sequence; performing re-pressing on a PET thin film comprisinga nanometer conductive material, and the obtained cellulose template at a temperature of 80-110 DEG C at pressure of 5-15MPa; and immersing the mixture in a washing liquid and performing hot pressingtreatment. By adoption of the preparation method, the requirements of low carbon, green and environmental protection and humanization of people on the modern flexible electronic products can be satisfied; compared with the conventional flexible transparent conductive thin film, the flexible transparent conductive nanometer thin film has the characteristics of low ration, high transparency, low sheet resistance, high mechanical strength, simple process, wide application and the like; and the comprehensive performance of the product is also better than the related indexes of the flexible transparent conductive thin film on the market.
