| Abstract | Polyaniline (PANI) has been recognized as an ideal candidate for electrode materials in supercapacitors. However, the relatively low electrical conductivity and poor cyclic stability severely limit its potential applications. Therefore, a proper substrate with carefully designed nanostructures for PANI immobilization is highly desirable for realizing its full performance. In this study, three-dimensional porous graphene–carbon nanotube (p-GC) hybrid papers with high porosity, excellent electrical conductivity and good flexibility were utilized as a nano-scaffold for the in situ polymerization of PANI, thus obtaining flexible p-GC/PANI ternary hybrid papers with hierarchical nanostructures. The good electrical conductivity and optimized porous nanostructure of the p-GC hybrid paper provides improved conductive pathways and high surface area, ensuring the efficient utilization of the pseudocapacitance of PANI. Thus, the ternary hybrid paper exhibits a high specific capacitance of up to 409 F g−1 at a current density of 10 A g−1, as well as excellent rate and cyclic performance. Furthermore, the dimensional confinement of PANI particles within the p-GC framework effectively prohibits volume expansion and shrinkage upon electrolyte soakage and cycling. Therefore, the p-GC hybrid paper with tunable hierarchical nanostructures can act as a promising substrate to enhance the electrochemical properties of PANI or other electroactive materials and can be easily extended to the design of next-generation high-performance flexible supercapacitors. |
