“…These sheets can be easily surface modified [4] or functionalized through covalent grafting [5][6]. Once GtO is exfoliated, it can be converted into reduced graphene oxide (rGO) [7] by a variety of methods, such as: a) chemical by employing reducing agents like hydrazine hydrate [8][9][10], NaBH 4 [11][12], urea [13], hydroxylamine [14], pyrrole [15], etc., b) microwaves [16][17][18][19], c) thermal annealing [20][21][22][23][24][25] and d) hydrothermal processing [26][27][28][29][30][31]. rGO has attracted intensive attention mainly because it can be cheaply produced on a large scale from GtO.…”

“…56 The small τ 0 value implies the good rate capability, and the obtained τ 0 value for C-rGOF12-T160 is smaller than those of porous graphene materials previously reported, 34,36,54,55,57 indicating excellent rate performance of C-rGOF12-T160. 13,34,51,[58][59][60][61][62][63][64][65][66] The measurements in long-term cyclic stability of the capacitor show that the C s values of SCs assembled by C-rGOF12-T160 slightly decrease with the increase of the cycle number, which may be originated from the structural change and the increment of the internal resistance (iR drop) during the cyclic process ( Figure 8D).…”

Summary By using oxalic acid (OA) as template and reducer, a novel approach is developed to prepare reduced graphene oxide films with capsular pores (C‐rGOFs) under a hydrothermal condition. The effect of preparation conditions including concentrations of OA and reaction temperatures on the films' structure and capacitive performances has been systematically investigated. The optimal C‐rGOF shows uniform capsule‐like morphology and exhibits a density of 1.18 g cm−3. Tested by using a two‐electrode system, the optimal film shows gravimetric specific capacitance of about 234.9 F g−1 and volumetric specific capacitance of 277.2 F cm−3. Additionally, the optimal film which shows good rate capability can retain 63.9% of initial capacitance at high scan rate of 1.0 V s−1, which is much higher than that of the controlling reduced graphene oxide film (rGOF, 180.5 F g−1, 373.6 F cm−3 and retain only 45.0% of its initial capacitance at 1.0 V s−1). The cells assembled by the optimal C‐rGOF exhibit maximum energy density of 7.5 Wh kg−1, power density of 16.9 kW kg−1, and excellent cycling stability with 91.2% capacitance retention after 21 000 cycles. It is believed that this method can be developed as a useful strategy to prepare rGO‐based materials for energy storage applications.

“…The use of MWCNTs has also been reported to increase double layer capacitance and conductivity [75,81]. The design of the supercapacitor has been studied as a key factor for enhancing the electrolyte-accessible surface area and increase the capacitance of the system when compared with traditional configurations [77]. Following, the most interesting works related to G-based fabrics for supercapacitor applications will be briefly summarized.…”

Graphene has emerged as a revolutionary material in different fields of science and engineering due to its extraordinary properties such as: high electron mobility, high thermal conductivity, mechanical properties, easy functionalization, etc. The field of textiles is continuously integrating new materials to provide fabrics with new functionalities, hence its incorporation on fabrics was a logical step. Its application to the field of textiles has been recently reported, which has allowed the development of textiles with different functionalities such as: antistatic, UV-protecting, electroconductive, photocatalytic, antibacterial, energy storage in supercapacitors, electrodes for batteries, thermal conductivity, sensors, etc. Up to date no review has been written regarding graphene-based fabrics and their applications. The present review aims to fill the existing gap and provide perspectives into the preparation and applications of graphene-based fabrics and yarns.
