Preparation method of high-orientation conductive polymer film, prepared film and application thereof

Abstract

The invention claims a preparation method of a high-orientation conductive polymer film. The method comprises the following steps: preparing a high-orientation polymer film by adopting a melt stretching method, then modifying the electrode for electrochemical polymerization by using the polymer film, and finally electrochemically polymerizing the conductive polymer monomer on the modified electrode to form the high-orientation conductive polymer film. The conductivity of the conductive polymer film is anisotropic, namely showing obviously different conductivity in the polymer orientation film direction vertical or parallel to the modified electrode. The conductive polymer film can be applied to the fields of light emitting diodes, solar batteries and filed effect transistors and the like.

Description

technical field

[0001] The invention relates to a method for preparing a film, in particular to a method for preparing a highly oriented conductive polymer film by electrochemical polymerization, the film prepared by the method and its application. Background technique

[0002] Electronic devices based on organic polymer semiconductors have attracted widespread attention, such as solar cells, organic field-effect transistors, and light-emitting diodes. Organic polymer semiconductor materials have the following main advantages: the structure of organic semiconductors can be adjusted from the molecular level to improve their properties, low cost, solution processability, light weight and easy large-scale processing and preparation. Due to the low order and amorphous structure of organic polymer semiconductors, there is still a relatively large gap between their conductivity and inorganic semiconductors. In order to prepare high-efficiency electronic devices, people try to use...
