Overview

Randomized trial demonstrates increased charge storage in multifunctional structural supercapacitors, suggesting improved design efficiency.

Key Points

  • This research aims to enhance the electrochemical performance of carbon fiber structures by modifying them with polyaniline nanofibers.
  • Polyaniline nanofibers were grown on woven carbon fiber fabrics via in situ electrochemical polymerization.
  • The electroactive nanofibrous interface was characterized for its charge storage capabilities.
  • Three-point bending tests were conducted to assess mechanical strength.
  • PANI‐NF@WCF electrodes achieved an areal capacitance of 3.4 F cm -2 at 1 mA cm -2, significantly higher than the WCF electrode.
  • The epoxy resin-based supercapacitor demonstrated an areal capacitance of 51.7 mF cm -2 at 0.5 mA cm -2, with a maximum energy density of 39.8 mWh kg -1.
  • Flexural strength recorded at 16.3 MPa with a flexural modulus of 1.9 GPa, indicating a strong structural integrity.
