Abstract

The invention belongs to the field of high-conductivity polymer flexible films, and especially relates to a method for preparing a conductivity-improved conductive polymer flexible film by utilizing an acid immersing process to change the microstructure of the surface of the conductive polymer flexible film. A high-conductivity PEDOT flexible film is prepared on the surface of a flexible base by utilizing a gas-phase polymerization method, and through the simple acid immersing method at room temperature, the PEDOT flexible film surface is subjected to fibration change, and the conductivity of the PEDOT flexible film is substantially improved by 40% or more. The prepared conductive polymer flexible film composed of the flexible base and the PEDOT flexible film with the fibrosis surface is applicable to flexible electronic devices.

Description

technical field [0001] The invention belongs to the field of highly conductive polymer flexible films, in particular to a method for preparing a conductive polymer flexible film with improved conductivity by using an acid soaking method to change the microstructure of the surface of the conductive polymer flexible film. Background technique [0002] In daily life, people pay more and more attention to the portability and novelty of the optoelectronic devices used, so the flexibility of devices is increasingly becoming the future development trend. The electrode material of existing optoelectronic devices is generally indium tin oxide (ITO), which is characterized by high conductivity and good permeability. However, due to its brittleness, it cannot be applied to flexible optoelectronic devices. In addition, the rare earth elements in ITO are expensive and have limited resources, so the research on new alternative materials has attracted widespread attention. [0003] Conduc...
