FILM FOR PREPARING OPTOELECTRONIC DEVICE, PREPARATION PROCESS AND OPTOELECTRONIC DEVICE THEREOF

摘要

The present invention relates to a film for preparing an optoelectronic device, the preparation process and the optoelectronic device thereof. Aiming at the problem in the prior art that the transparency and the conductivity of the flexible electrodes cannot be met at the same time, the present invention provides a conductive polymer-carbon nanotube composite material, which comprises carbon nanotubes and conductive polymers. The composite material with high transparency and high conductivity is prepared by dispersing the carbon nanotubes uniformly in the conductive polymer matrix, and the composite material can be used for preparing optoelectronic devices such as flexible transparent electrodes, etc., to be applied in the display screens of mobile phones, notebook computers, high definition televisions and digital cameras. The carbon nanotubes form a network in the conductive polymers to provide channels for electron transportation, thereby increasing the conductivity of the conductive polymers by 3 to 5 orders of magnitude. At the same time, a red shift occurs to the absorption band of the doped conductive polymers, so that its transparency in the visible region is also increased. Therefore, a flexible transparent electrode with both improved transparency and improved conductivity can be produced.
