Problems solved by technology

On the other hand, compared with conductive films made of inorganic conductive materials, organic conductive films formed of conductive polymers have problems such as low heat resistance, low weather resistance, and poor durability.
For example, polythiophene-based conductive polymers (such as PEDOT / PSS) are widely known as conductive polymers, but their conductivity is known to decrease over time, and it is thought that the deterioration mechanism is caused by oxygen in the air Oxidation reaction (for example, non-patent document 1)
[0010] In addition, the inventors of the present invention have also realized that when a uniform film is formed using a polythiophene-based conductive polymer, its conductivity is gradually lost, and it is not durable for long-term use.

Abstract

PURPOSE: An organic conductive film is provided to have excellent durability and is suitable as an anti static film or a transparent electrode and to be used for an optical film, packing material, transparent electrode film, and liquid crystal display cell. CONSTITUTION: An organic conductive film comprises a conductive composition which contains a conductive polymer. The maximum height of the single side thereof(Rz) is 35% or more of the average film thickness. The conductive polymer is a polythiophene-based conductive polymer. The polythiophene-based conductive polymer is a composite of a poly(3,4-dialkoxythiophene) or a poly(3,4-alkylenedioxythiophene), which has a repeating structure indicated in chemical formula 1; and a dopant. In chemical formula 1, each of R1 and R2 is hydrogen, a C1-4 alkyl group, or a mono-substituted or unsubstituted C1-4 alkylene group.

Description

[0001] 【Technical field】 [0002] The present invention relates to an organic conductive film excellent in durability, an optical film, a packaging material, a transparent electrode film, and a liquid crystal display cell having such an organic conductive film. [0003] 【Background technique】 [0004] As a transparent conductive film (transparent electrode etc.) used for a display screen application etc., the conductive film formed of inorganic system transparent conductive materials, such as ITO, is known. [0005] However, the formation of a transparent conductive film using ITO is generally performed by methods such as sputtering using a large-scale vacuum apparatus, and the production cost tends to increase. [0006] In addition, ITO contains indium which is a rare metal (so-called rare metal), and there is concern about the depletion of its resources. [0007] Therefore, in recent years, attempts to use conductive polymers as a substitute for ITO have been actively attemp...
