Abstract
Biosynthetic route for the synthesis of nanoparticles involving fossil extract is a modest eco-friendly process, the study focused on a relatively new class of functional materials known as polymerized ionic liquids The synthesized nanoparticles were then characterized through UV-Visible, FTIR and X-ray diffractionspectroscopy.Nanoparticles incorporated in polymers providing an exciting base for newer technology for the development of cost effective electrochemical and devices. Poly (vinyl alcohol) (PVAM) is one of the eco-friendly semi-crystalline polymers which has inter- and intra-molecular hydrogen bonds, whose degree is greatly dependent on the texture of the polymer. We have fabricated a naturally plasticized nanopolymer electrolyte membrane with high ionic conductivity using nano MMT incorporated in PVAM. Randomly interwoven nano-fibrous structures are generally preferred for electrolyte systems due to their continuous structure. The use of nano-composites provided a 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 fibres naturally becomes highly porous. Nano composite membrane due to its high porosity becomes a major responsive factor to enhance the ionic conductivity. We have considered a comparative study of these fabricated nano-composites. The structural behaviour of the polymer nano-composite membrane was investigated by XRD, FTIR, optical microscopy and scanning electron microscopic technique. XRD curve revealed the amorphous nature of membrane, which is favourable for the better conduction and sensing behaviour, as the conductivity-frequency plots showed the Universal power law. The asymmetric shape of the Dielectric relaxation plots given a strong evidence of low frequency dispersion and deviation from the pure Debye behaviour.
