Design of Conductive Overcoating Layer Based on Hybrid Composites to Improve the Physical Stability of Flexible Transparent Conductive Films |
| 초록 |
Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is one of the conductive polymers with excellent conductivity and transparent conductive material. However, the PEDOT:PSS film exhibits rapid deterioration in physical properties under high temperature and high humidity conditions. A protective layer that can be applied to a flat and flexible transparent conductive film was prepared by combining silica sol and organic polymer. (3-Glycidyloxypropyl)trimethoxysilane (GPTMS) was used as a precursor of a silica sol that hydrolyzes under water to form silanol groups and self-condensates to form a sol under acidic conditions. Since the protective layer is insulating, the overcoat itself is made conductive by adding PEDOT:PSS to the protective layer to allow electrical conduction. The network structure on the surface of the overcoating layer can improve chemical stability by blocking oxygen and moisture. |
