Synthesis of nanoporous hypercrosslinked polyaniline (HCPANI) for gas sorption and electrochemical supercapacitor applications

Abstract

Nanoporous hypercrosslinked polyaniline with SA_BET of 1059 m² g⁻¹ has been synthesized. The specimen showed CO₂ and CH₄ uptake of 3.52 and 1.01 mmol g⁻¹, respectively at 273 K, and H₂ storage capacity of 1.85 wt% at 77 K and 1 bar. The material has a high specific capacitance of 410(±5) F g⁻¹ and has shown good cyclability (100% retention) up to 1000 cycles.
