Highly conducting silver nanowire‐polyacrylonitrile hollow fibres for flexible supercapacitors

Abstract

A new approach for making stable, flexible, and conductive hollow fibres of poly (acrylonitrile) using dry-jet-wet spinning technique is investigated, wherein the inner walls of the poly (acrylonitrile) hollow fibres are deposited with silver nanowires using their dispersion in the bore fluid. The bore fluid plays a crucial role in determining the morphology and flexibility of the hollow fibres and entrapment of long silver nanowires on the inner walls. Fibres with AgNW layer having high conductivity of~10 4 Scm −1 are obtained with the use of~2 wt% of silver nanowires. The conducting fibres are successfully assembled into coaxial configuration to yield highly stable, flexible supercapacitors with capacitance value of 128 Fcm −3 . The unique morphology of these conductive hollow fibres opens the possibility of making flexible and stable devices for wearable electronics.

“…AgNWs were synthesized via Solvothermal technique [ 50,51 ] using PVP (5.8 g) in glycerol (190 mL). After dissolving both under continual stirring at 1000 rpm at 90 °C, AgNO 3 (1.58 g) was added to the solution at 50 °C and stirred for another 15 min.…”

“…[8][9][10] Although they have different energy storage mechanisms, the electrode material is still key point to enhance performance of supercapacitors. [11][12][13][14][15] Higher capacity and more electroactive sites are focal points in the developments of electrode materials. Among electrode materials, transition metal oxides (TMOs) show the higher performance ascribed to their complex valence states, while carbon materials usually shows a lower performance.…”

“…To research the supercapacitors clearly, the supercapacitors have been classified into two main types, the electric double layer capacitors (EDLC) and the pseudocapacitors, being sorted by their different energy storage mechanisms . Although they have different energy storage mechanisms, the electrode material is still key point to enhance performance of supercapacitors . Higher capacity and more electroactive sites are focal points in the developments of electrode materials.…”
