Abstract
Proposed are a dodecyl sulfate-doped PEDOT film and a manufacturing method therefor, the method including: coating, on a substrate, an oxidizing agent film including a dodecyl sulfate metal salt such as Fe(DS)3; and forming a PEDOT film by vapor phase polymerization. The dodecyl sulfate-doped PEDOT film according to the present disclosure has excellent electrical conductivity so as to be capable of replacing a metal, and has excellent mechanical durability, light transmittance, and aqueous solution stability.
Claims24
A PEDOT film including dodecyl sulfate as a dopant.
An electronic device including:
- a PEDOT film including dodecyl sulfate as a dopant.
A method of manufacturing a PEDOT film, the method comprising:
