Effects of three fabric weave textures on the electrochemical and electrical properties of reduced graphene/textile flexible electrodes

Abstract

Textile textures formed through woven, knitted or nonwoven weaving technology have critical effects on the electrical and electrochemical properties of flexible electrodes. Therefore, the effects of textile structures, including porosity and pore configuration, on the loading amount of reduction graphene (RGO), the electrical and electrochemical properties were systematically studied. The results show that knitted fabric had the highest mass loading of RGO sheets and lowest sheet resistance among these three fabrics. However, the specific capacitance of woven fabric was optimum 40.5 F g À1 at a scan rate of 5 mV s À1 within the voltage window of 0-0.8 V, which was ascribed to its suitable porosity and pore size firmly anchoring the RGO sheets. Also, the RGO/woven cotton electrodes exhibited good cycling stability and excellent electrochemical stability without an obvious loss in the capacitive performance.The above results provide a theoretical basis for the selection of textile substrates for high-performance flexible electrodes.

Facile construction of a flexible and wearable electrode based on the hierarchical structure of RGO-coated cotton fabric with amorphous Co–Ni–B alloy

“…11 The specic capacitance of RGO/cotton fabric resulted from the double-layer mechanism of RGO, whose weakness is the low capacity. 30,31 As for Co-Ni-B/fabric composite, its specic capacitance originated from the pseudocapacitance mechanism. However, the capacity was limited by the insulated cotton fabric substrate.…”

Influence of microscopic features on the self-cleaning ability of textile fabrics

“…The woven fabric exhibited the best electrochemical performance compared with the other two fabrics, 93 as the porosity and pore configuration can affect the self-cleaning ability. Jaouani et al 94 measured woven fabric structural and material parameters that affect dielectric properties and fabric surface roughness. The results were obtained by using 12 different fabric structures to measure their roughness.…”
