Large-scale synthesis of size- and thickness-tunable conducting polymer nanosheets via a salt-templated method

摘要: Conducting polymer nanosheets are promising for many intriguing applications owing to their unique optical and electrical properties. However, it is still challenging fabricate size- thickness-tunable conducting with the feature of large scalability in a facile manner. Here, we developed new approach massive synthesis various (polypyrrole (PPy), polyaniline (PANi), polyethylene dioxythiophene (PEDOT)) at gas–solid interface between monomeric gas CuCl2·2H2O salt. The thickness as-obtained can be tuned from ∼2.1 ∼8.8 nm. Furthermore, highly conductive, flexible large-area (∼60 cm2) PPy film transparency ∼85% was prepared on surface film. nanosheet-assembled free-standing electrode exhibited high volumetric capacitance ∼320 F cm−3 great rate capability. This cost-effective method could massively produce nanosheets, potential practical applications.
