STRUCTURAL AND IONIC TRANSPORT STUDY OF NATURALLY PLASTICIZED NANO-POLYMER ELECTROLYTE FOR DEVICE APPLICATION
Abstract
Nano polymer electrolytes are providing an exciting base for newer technology for the development of  cost effective electrochemical devices and their potential applications such as in solid-state batteries (fuel cells, solar cell, secondary batteries smart windows etc.). Poly(vinyl alcohol) (PVA) is one of the eco-friendly semicrystalline polymer which has inter- and intra-molecular hydrogen bonds, whose degree is greatly dependent on the texture of the polymer. Aloe vera has an important outer fibrous vascular bundle layer and the inner colourless parenchymatic gel. Randomly interwoven nano-fibrous structures are generally preferred for electrolyte systems due to their continuous structure. The use of nano-filler provided better polymer interface as well as the high free volume size, through which molecules transport occurs in nano-composite membrane matrix. The advantage of a surface comprised of ultra-fine, continuous nano fibers naturally becomes highly porous. The high porosity is the major responsive factor to enhance the ionic conductivity which was determined through impedance study in the temperature range 298-373 K. Key words: Poly-venyl alcohol (PVA), Aloe-vera gel (AV), natural plasticizerReferences
