“…In a VRB system, common graphite-or carbon-based electrodes often exhibit inadequate electrochemical activity and kinetic reversibility toward the electrochemical reactions between the vanadium species. In early research, various approaches were employed to optimize the graphite or carbon electrodes for improved electrochemical activity, including heat treatment, [ 74 ] chemical treatment, [ 75 ] electrochemical oxidation, [ 76 ] and doping or depositing other metals on carbon fi bers. [ 77 ] Among these, heat treatment is probably the simplest yet most effective way to activate the carbon-based electrode.…”

With the increasing need to seamlessly integrate renewable energy with the current electricity grid, which itself is evolving into a more intelligent, efficient, and capable electrical power system, it is envisioned that energy‐storage systems will play a more prominent role in bridging the gap between current technology and a clean sustainable future in grid reliability and utilization. Redox flow battery technology is a leading approach in providing a well‐balanced solution for current challenges. Here, recent progress in the research and development of redox flow battery technology, including cell‐level components of electrolytes, electrodes, and membranes, is reviewed. The focus is on new redox chemistries for both aqueous and non‐aqueous systems.

“…Meanwhile, it should be necessary to have good interfacial adhesion between CFs and matrix polymers for produce the high performance CFRTPs. Numerous methods for surface treatment of CFs, such as chemical modification [24,34], electrochemical oxidation [35][36][37][38][39][40][41], and plasma treatment [16,17,19,[21][22][23]29] have been studied to assure good interfacial adhesion. The basic idea of the CF surface modification is as follows.…”

Abstract. Acrylic polymers have high potential as matrix polymers for carbon fiber reinforced thermoplastic polymers (CFRTP) due to their superior mechanical properties and the fact that they can be fabricated at relatively low temperatures. We focused on improving the interfacial adhesion between carbon fibers (CFs) and acrylic polymers using several functional monomers for co-polymerization with methyl methacrylate (MMA). The copolymerized acrylic matrices showed good adhesion to the CF surfaces. In particular, an acrylic copolymer with acrylamide (AAm) showed high interfacial adhesive strength with CFs compared to pure PMMA, and a hydroxyethyl acrylamide (HEAA) copolymer containing both amide and hydroxyl groups showed high flexural strength of the CFRTP. A 3 mol% HEAA-copolymerized CFRTP achieved a flexural strength almost twice that of pure PMMA matrix CFRTP, and equivalent to that of an epoxy matrix CFRP.

“…A suited interface generally leads to better composite properties, so many effective interfacial modifications for CF forming suited interface have been investigated, such as grafting, coating and oxidation. [1,2] One of many possible ways to improve the interfacial adhesion in composites is the grafting of coupling agents onto CF surface.…”

The influence of chain lengths on interfacial performances of carbon fiber/polyarylacetylene composites was studied. For this purpose, four coupling agents, methyltrimethoxysilane, propyltrimethoxysilane, octyltrimethoxysilane and dodecyltrimethoxysilane, were grafted onto fiber surface to obtain different chain lengths. The resulting carbon fiber surface was characterized by XPS and dynamic contact angle test. Interfacial adhesion in the resulting fiber reinforced polyarylacetylene resin composites was also evaluated by fracture morphology analysis and interfacial shear strength test. It was found that the interfacial adhesion in composites greatly increased with chain lengths on fiber surface. The improvement of interfacial adhesion was attributed to the interaction between the chain of coupling agents on fiber surface and that of polyarylacetylene resin at the interface.
