Development and experimental characterization study of cesium doped zinc oxide polymer conductive films for sensing applications

Abstract

In this research study we report the successful preparation of cesium doped zinc metal oxide nanoparticles by solution combustion technique further incorporated into polyurethane films synthesized from bio-degradable castor oil, for study of piezo-conductive property. The composite films prepared with filler weight percentages of 0.5, 1.0, 2.0 and 4.0 are studied for structural, mechanical, thermal, electro-mechanical and weatherability properties. Studies revealed successful formation of urethane links and good dispersion of nanoparticles in the prepared films. Films under tensile and compression loading showed promising electro active results with maximum volume conductivity values of 1.226E−7Scm−1 at 30N compression load. The developed films show good compatibility to be employed in corrosive and acidic environments with safe working temperature upto 160°C.
