“…PVA is a promising candidate for host polymer due to its inherent characteristics like good tensile strength, mechanical strength, non-toxicity, cost effectiveness, good optical properties, high temperature resistance and high hydrophilicity [95][96][97]. The high hydrophilicity of PVA is due to the presence of a large extent of the polar hydroxyl group.…”

In this paper, we review different types of polymer electrolytes, recent approaches and technological applications of polymer electrolytes. The report first discusses the characteristics, advantages and applications for three types of polymer electrolytes: gel polymer electrolytes, solid polymer electrolytes and composite polymer electrolytes. Next, we discuss the features and performance of different polymer hosts based on some important and recently published literature. Recent progress of some approaches used in improving the performance of the polymer electrolytes is highlighted. The last part of the review includes the technological applications of some electrical energy storing/converting devices: electrochemical capacitors, batteries, fuel cells and dye-sensitized solar cells. It is also stressed that the technological advancement in the polymer electrolytes plays a pivotal role in the development of energy storing/converting systems.

“…Although PVA-coated electrodes have been developed for electrochemical sensors [116,117], electrochemical surface immobilisation of PVA has received limited attention. Recently, a novel GCE covalently modified with PVA has been fabricated through an electrochemical oxidation procedure and was used as an effective sensor for selective and sensitive determination of UA, AA and dopamine individually in the presence of the other two species [118].…”

The present review has sought to explore the technological advances that have been made in recent years towards the selective analysis of uric acid and critically evaluate how they could, in fact, be exploited as a basis for a multi analyte sensor incorporating uric acid detection. Numerous strategies have evolved in recent years but these have invariably focused on the manufacture and response characterization of discrete sensors. Various methods of obtaining selective detection such as use of uricase enzymes, nanoparticles, carbon nanotubes, polymers, conducting polymers and MIPs are also discussed along with the clinical relevance of UA determination.

“…Acidic PVA hydrogel membrane electrolytes (PHMEs) with varied HClO 4 concentrations were prepared by a solution casting method 18 in which a mixture of an aqueous solution of PVA (M.W. ≈ 1,25,000, SD fine-chem Ltd., India) and an optimized quantity of glutaraldehyde (25% aqueous solution, Merck Ltd., India) was cast on to a glass petri dish and left at ambient conditions of temperature and pressure for about 12 h to allow water to evaporate.…”

“…17 The -OH groups of PVA react with -CHO groups of certain aldehydes to form acetal or hemiacetal linkages under acidic conditions. 18 The resultant polymeric entity is water insoluble and gellike in nature. It can be cast to form thin large surface-area membranes suitable for use as electrolytecum-separator in ECs.…”

Abstract. Polymer electrolytes are known to possess excellent physicochemical properties that are very useful for electrochemical energy systems. The mobility in polymer electrolytes is understood to be mainly due to the segmental motion of polymer chains and the ion transport is generally restricted to the amorphous phase of the polymer. Gel polymer electrolytes (GPE) that are formed using plastizicers and polymers along with ionic salts are known to exhibit liquid-like ionic conductivity while maintaining the dimensional stability of a solid matrix. In the present study, the preparation and characterization of poly(vinyl alcohol)-based hydrogel membranes (PHMEs) as electrolytes for electrochemical capacitors have been reported. Varying HClO 4 dopant concentration leads to different characteristics of the capacitors. The EC comprising PHME doped with 2 M HClO 4 and black pearl carbon (BPC) electrodes has been found to exhibit a maximum specific capacitance value of 97 F g -1 , a phase angle value of 78°, and a maximum charge-discharge coulombic efficiency of 88%.
