“…The volume change of EAPs based on porous carbons such as CDC on the other hand is caused by the intercalation of ions due to the electric double layer charging of the electrodes [10,11]. Generally it is understood that high electric double-layer capacitance of porous carbon is related to high surface area and precise pore size distribution according to electrolyte used [12,13].…”

“…In principle, supercapacitors store charges at the interface between electrode and electrolyte, thus large specific surface area (SSA) of electrode is favorable for high capacitance [1]. Therefore, many materials with large SSA were used as electrode, such as activated carbons [2,3], carbide-derived carbons [4,5], and carbon nanotubes [6,7]. Two-dimensional (2D) materials prepared by exfoliating precursors with layered structure [8,9] have high SSA, which are regarded as one of promising candidates for supercapacitor electrodes.…”

Two-dimensional (2D) carbide Ti 3 C 2 was synthesized by exfoliating Ti 3 AlC 2 in HF solution and used for supercapacitive performance investigation in 3 M KOH electrolyte. The specific surface area (SSA) of as-synthesized Ti 3 C 2 was 22.35 m 2 /g. Ti 3 C 2 -based supercapacitor electrodes exhibited good energy storage ability and had a volumetric capacitance 119.8 F/cm 3 at the current density of 2.5 A/g. Moreover, the addition of carbon black into Ti 3 C 2 powders greatly improved the performance of Ti 3 C 2 -based capacitors because carbon black restrained the preferred orientation of 2D Ti 3 C 2 , providing fast ion transport channels, and in turn, decreasing electrical resistance from 16.7 Ω to 3.5 Ω.

“…The contact metal electrodes are usually made of copper or gold to ensure good conductivity and stability. [ 22,51 ] In most cases, they Young's modulus. Thus the challenge for development of high performance IPMC actuators still exists in large strain and fast response under low voltages, as well as in understanding the mechanism on how the intrinsic properties of carbon nanomaterial electrodes affect the actuation performance.…”

“…[ 36,51,54,56,126,127 ] As they may have larger effective electrochemical area or better dispersibility, the investigation on their electromechanical properties is also of great value. Such kinds of carbon materials include carbon nanofi bers, [ 54,56 ] carbidederived carbon [ 36,51,127 ] and nanoporous carbon [ 126 ] etc.…”

Bio-inspired actuation materials, also called artificial muscles, have attracted great attention in recent decades for their potential application in intelligent robots, biomedical devices, and micro-electro-mechanical systems. Among them, ionic polymer metal composite (IPMC) actuator has been intensively studied for their impressive high-strain under low voltage stimulation and air-working capability. A typical IPMC actuator is composed of one ion-conductive electrolyte membrane laminated by two electron-conductive metal electrode membranes, which can bend back and forth due to the electrode expansion and contraction induced by ion motion under alternating applied voltage. As its actuation performance is mainly dominated by electrochemical and electromechanical process of the electrode layer, the electrode material and structure become to be more crucial to higher performance. The recent discovery of one dimensional carbon nanotube and two dimensional graphene has created a revolution in functional nanomaterials. Their unique structures render them intriguing electrical and mechanical properties, which makes them ideal flexible electrode materials for IPMC actuators in stead of conventional metal electrodes. Currently although the detailed effect caused by those carbon nanomaterial electrodes is not very clear, the presented outstanding actuation performance gives us tremendous motivation to meet the challenge in understanding the mechanism and thus developing more advanced actuator materials. Therefore, in this review IPMC actuators prepared with different kinds of carbon nanomaterials based electrodes or electrolytes are addressed. Key parameters which may generate important influence on actuation process are discussed in order to shed light on possible future research and application of the novel carbon nanomateials based bio-inspired electrochemical actuators.
