Durometer test and impedance measurement of metal precursor reinforced polymer composites. (July 2018) - Joseph, Anandraj
Graphical abstract: Highlights: We demonstrated the preparation of metal precursor polymer composites. Morphology, softness and electrical properties disclosed. Decrease in activation energy of polymer composites observed. This investigation is feasible for domestic and industrial applications. Abstract: Polymer composites were preferred for the domestic and industrial applications due to unique high performance properties. In the present work we demonstrated the preparation of polyvinyl alcohol (PVA)/Copper bismuth sulphide (CuBi2 S3 ) metal precursor composites by solution blending. The decreased softness by 45% was confirmed as a function of metal precursor loading tested by shore – A durometer. It may be due to the presence of metal precursor in polymer system distinguished by Scanning Electron Microscope (SEM) techniques. We observed the influence of metal precursor on bulk resistance and impedance as function of temperature across the broadband frequency and wide temperature range. The dc conductivity obeys the Arrhenius relationship and confirmed the decrease in activation energy. This investigation may be feasible for the electrical and electronic domains.
