In this work, we report an efficient methodology to produce polyaniline hydrogel (PANI HDG) with high scalability, enhanced mechanical properties, and chemical stability. The conductive PANI HDG with excellent mechanical properties was synthesized through chemical interactions between PANI and polyvinyl alcohol (PVA) chains. PVA not only acted as a matrix for the hydrogel formation but also served as a steric stabilizer to control the sizes of PANI nanoparticles (NPs). To achieve further improvements in the mechanical, thermal, and electrical properties of the PANI HDG, graphene sheets were added and dispersed into the PANI HDG. A variety of characteristics of the PANI hydrogel, such as morphological, structural, thermal, mechanical, and electrochemical properties, have been thoroughly discussed. |
