Scalable Construction of Flexible Composite Textile Electrodes through In Situ Growth of Polyaniline Nanofibers on Carbon Cloths under Electric Field toward High Areal Capacitance Supercapacitors

The most promising development direction of polymorphous supercapacitors is to find a scalable and inexpensive strategy to fabricate textile electrodes besides endowing a flexible device with a high areal capacitance. Herein, we explore an interesting scalable fabrication of cost-effective composite textile electrodes by promoting the in situ nucleation and growth of a polyaniline nanofiber array on carbon cloth under an electric field and then ensuring enough monomers and moist condition for the successive growth of the array. The assembled all-solid-state supercapacitor possesses a maximum energy density of 86.3 mu Wh cm(-2) at 0.42 mW cm(-2) and excellent structural stability.
