“…Therefore, extensive investigation on micro-supercapacitors (μSCs) based on a number of printing, [2,3] lithography, [4][5][6][7][8] and laser (and/or ion) assisted methods [9][10][11][12][13] have been carried out. [28][29][30][31][32] Based on the doping and dedoping during the charging-discharging process, predoped conductive polymers show high capacitance and conductivity. First, complex fabrication process leads to high costs and low feasibility for scalability.…”

“…Secondly, most μSCs rely on a predesigned substrate, showing very poor compatibility with basic components for wearable devices, such as textile, paper, or plastic. [29,[40][41][42][43][44] Herein, by electrochemically depositing sac-like structured PPy nanowires (PPyNWs) onto predesigned fluorine doped tin oxide coated glass (FTO), μSC was fabricated with extremely low cost. Therefore, a low-cost fabrication approach for a highly reliable, durable, and modifiable μSCs system is of great significance.…”

and poly(3,4-ethylenedioxythiophene) (PEDOT). The highly conjugated polymer chains can be reversibly assigned electrochemical properties by a doping/dedoping process. [9][10][11] By regulating and controlling the level of doping, their conductivities can be tuned in a wide range, from 10 −10 to 10 4 S cm, spanning the entire range from insulators to semiconductors, to conductors. [12,13] Additionally, these conducting polymers retain the advantages of traditional polymers, such as low cost, convenient preparation, good affinity to many other materials, and high flexibility and durability. Recently, great efforts have been made to exploit the applications of conducting polymers as electrocatalysts for fuel cells and as electrode materials for supercapacitors. Considering the rapidly booming efforts undertaken in this cutting-edge research area, it is necessary to highlight the new discoveries and achievements in the past several years. Here, we introduce the latest advances in conducting-polymer-based materials for fuel cells and supercapacitors, and focus on the strategies employed to improve their electrocatalytic and electrochemical performance. Conducting-Polymer-Based Catalysts for Fuel CellsFuel cells are promising green energy-conversion devices that convert chemical energy of various fuels directly into electric energy under electrochemical redox reactions. This technology provides intriguing applications in portable energy sources [14,15] and has attracted increasing attention in recent years. [16][17][18][19] Such energy-conversion systems require highly efficient electrocatalysts to trigger the oxygen reduction reaction (ORR) that occurs at the fuel cell's cathode. Platinum/ carbon (Pt/C) composite is demonstrated to be the most efficient catalyst used for fuel cells. [20][21][22] However, high price, scarcity, poor utilization efficiency, and easy carbon monoxide poisoning greatly limit its commercial applications. [23] Therefore, development of low-cost, stable, and efficient electrocatalysts for ORR is a major challenge in the field of fuel cells. [24][25][26][27][28] Owing to their highly tunable conductivity, good electrocatalytic activity, and satisfactory electrochemical stability, conducting polymers are considered to be promising electrocatalyst materials for the ORR. [29] Initially, conducting-polymer-based electrodes were fabricated through direct casting of neutral To alleviate the current energy crisis and environmental pollution, sustainable and ecofriendly energy conversion and storage systems are urgently needed. Due to their high conductivity, promising catalytic activity, and excellent electrochemical properties, conducting polymers have been attracting intense attention for use in electrochemical energy conversion and storage. Here, the latest advances regarding the utilization of conducting polymers for fuel cells and supercapacitors are introduced. The strategies employed to improve the electrocatalytic and electrochemical performances of conducting-polymerbased materials are prese...

“…Furthermore, the PPy also provides a greater degree of flexibility in electrochemical processing [21, 22]. Conducting polymers can improve the device by undergoing a redox reaction to store a charge in the bulk of the material and hence increase the energy stored and reduce self-discharge [23, 24].…”

A nanocomposite comprising of polypyrrole and reduced graphene oxide was electrodeposited onto a carbon bundle fibre (CBF) through a two-step approach (CBF/PPy-rGO-2). The CBF/PPy-rGO-2 had a highly porous structure compared to a nanocomposite of polypyrrole and reduced graphene oxide that was electrodeposited onto a CBF in a one-step approach (CBF/PPy-rGO), as observed through a field emission scanning electron microscope. An X-ray photoelectron spectroscopic analysis revealed the presence of hydrogen bond between the oxide functional groups of rGO and the amine groups of PPy in PPy-rGO-2 nanocomposite. The fabricated CBF/PPy-rGO-2 nanocomposite material was used as an electrode material in a symmetrical solid-state supercapacitor, and the device yielded a specific capacitance, energy density and power density of 96.16 F g− 1, 13.35 Wh kg− 1 and of 322.85 W kg− 1, respectively. Moreover, the CBF/PPy-rGO-2 showed the capacitance retention of 71% after 500 consecutive charge/discharge cycles at a current density of 1 A g− 1. The existence of a high degree of porosity in CBF/PPy-rGO-2 significantly improved the conductivity and facilitated the ionic penetration. The CBF/PPy-rGO-2-based symmetrical solid-state supercapacitor device demonstrated outstanding pliability because the cyclic voltammetric curves remained the same upon bending at various angles.Graphical AbstractCarbon bundle fibre modified with porous polypyrrole/reduced graphene oxide nanocomposite for flexible miniature solid-state supercapacitor.Electronic supplementary materialThe online version of this article (doi:10.1186/s11671-017-2010-3) contains supplementary material, which is available to authorized users.
