“…Hence, all‐solid‐state SCs (ASSSCs) have aroused wide interest because of their small size, light weight, convenient manufacture, and wide working voltage 92. The gel polymer electrolytes have been considered as promising electrolytes due to their ability to provide electrode protection, freedom from leakage, flexibility, excellent ionic conductivity, and stable electrochemical properties 93. Among them, PVA has been regarded as one of the most promising gel polymer electrolytes because of its excellent chemical stability, outstanding conductivity, nontoxicity, and low cost.…”

Nickel oxide, as a typical pseudocapacitive material, holds great promise for boosting the energy storage capability of supercapacitors (SCs) owing to its great advantages, such as high theoretical capacitance value, low‐cost, good stability, and environmentally benign nature. Nevertheless, many obstacles, including low intrinsic conductivity and limited surfice electrochemically active sites, need to be overcome before its practical implementation. In this review, the recent advances on nickel oxide‐based electrode materials are outlined with particular attention paid to strategies for enhancing their SC performance. To begin, an introduction to the physical and chemical properties of nickel oxide and its charge storage mechanisms is presented, followed by a discussion of the obstacles to its widespread implementation and the corresponding strategies for constructing high‐performance nickel oxide‐based electrode materials. After that, recent progress in the use of organic electrolyte systems to achieve improvements in integrated device performance is highlighted. To conclude, a detailed discussion on future trends and opportunities associated with NiO‐based electrode materials for future SCs is provided.

“…With this morphology, the properties of the immiscible polymers are usually better combined. [49][50][51] The aqueous phase of the microemulsion was composed of the precursor of PNIPAM single network and the hydrophobic phase with those of the PBA network. The photopolymerization, initiated by Darocure 1173 under UV irradiation, was monitored by FTIR in the near IR region.…”

“…One example was the incorporation of Fluorolink MD700 into an interpenetrating polymer network so that the chemical stability of an anion exchange membrane was enhanced to protect its air electrodes under extreme conditions. 7 Another example was to coat Fluorolink AD1700 and MD700 onto membranes for membrane distillation applications by taking the advantage of its hydrophobic nature. 8 Organic solvent nanofiltration (OSN), also known as solvent resistant nanofiltration (SRNF), is a separation technology aiming to recover organic solvents or concentrate valuable products in pharmaceutical, petrochemical, and food industries.…”

Fluoropolymer, with its high chemical stability and hydrophobicity, has great potential in applications involving organic solvents, e.g., organic solvent nanofiltration (OSN). An UV-curable fluorinated polymer, perfluoropolyether (PFPE, Fluorolink AD1700), was coated and polymerized onto a cross-linked polyimide substrate to modify its surface properties for OSN. The PFPE coating can convert the hydrophilic substrate to a hydrophobic membrane and narrow the pore size of the membrane to make it suitable for OSN applications. Different coating concentrations, ranging from 1 to 10 wt %, were applied, and the composite membranes were characterized in various organic solvents (acetonitrile, ethanol, isopropanol, and hexane). The permeances of these solvents were found to be inversely proportional to the products of their viscosities and molar volumes. The separation performance of the composite membrane coated by 10 wt % PFPE exhibited rejections of >90% to orange II sodium salt (MW = 350.32 g·mol–1) and remazol brilliant blue (MW = 626.54 g·mol–1) in isopropanol. The 7-day tests were also conducted to (1) separate tetracycline from ethanol/tetracycline solutions and (2) recover hexane from hexane/β-carotene solutions. The fluxes and rejections of both membranes do not fluctuate significantly during the 7-day continuous tests, with a performance comparable with and superior to most literature data. Therefore, the PFPE-coated membranes may have great potential to be next-generation OSN membranes for industrial applications.
