Water-Induced Degradation and Stabilization Strategies of PEDOT:PSS Films: A Review

This review follows how water uptake in PSS-rich regions changes PEDOT:PSS film structure, disrupts conducting pathways, and weakens adhesion. It compares solvent treatments, surfactants, crosslinking, and modification of PSS as stabilization approaches, with attention to the trade-offs among conductivity, mechanical properties, and water resistance.
