Substantial effort has been devoted to developments of both chemical and mechanical properties for optoelectronic devices in the past decade. The key of the development of those functionalities is the fabrication of conductive electrodes with desirable chemical and mechanical properties. Amongst conductive polymers, PEDOT:PSS is a promising material because of its high conductivity, transparency, and simple solution processability. PEDOT:PSS acts a critical role in many devices such as transparent electrodes, hole transport layers. However, its intrinsic properties such as acidic and hygroscopic can cause degradation or erosion at interfaces of devices. Here, we investigated the application of polymeric linker (Poly(ethylene glycol) diglycidyl ether) between PEDOT:PSS and other materials to solve the problems and enhance the interfacial properties. This linkage between hydrophilic PEDOT:PSS and biocompatible PEGDE lead to high adhesion as well as high stability in aqueous environments. |
