Optoelectronic devices, such as liquid crystal displays(LCDs), light-emitting diodes (LEDs), solar cells, touch panel displays, lasers, and detectors, have been attracting intense attention, due to their strong application in many aspects. In particular, Poly(3,4-ethylenedioxythiophene):Poly(styrenesulfonate) (PEDOT:PSS) with high transparency and superior mechanical flexibility is an excellent material as the transparent electrode. However, the pristine PEDOT:PSS films has a major problem of the low conductivity. In this work, we have tried to improve of low conductivity PEDOT:PSS and non-visibility patterned conductivity PEDOT:PSS by using novel materials with photo-reactive group. The conductivity of PEDOT:PSS films was significantly enhanced depended on the amount of novel materials and the photo-reactive difference of novel materials. The mechanism for the conductivity enhancement of PEDOT:PSS with novel materials is attributed to the phase separation of PSS chain from PEDOT:PSS. |
