Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is one of the conductive polymers with excellent conductive and transparent conductive materials. However, since PEDOT has insolubility insoluble in water and solvent, it introduces a primary dopant, Polystyrene sulfonic acid (PSSA) is hydrophilic and has low stability in water or chemical conditions. As a result, the PEDOT:PSS film exhibits a rapid deterioration in physical properties under high temperature and high humidity conditions. A protective layer that can be applied on a flat flexible transparent conductive film was prepared by combining silica sol and organic polymer. (3-Glycidyloxypropyl) trimethoxysilane (GPTMS) was used as a precursor for the silica sol, which hydrolyzed under moisture to form silanol groups and self-condensed to form a sol under acidic conditions.
