PANI ferrites nanocomposites synthesis characterization electrical and gas sensing properties

Abstract

In recent years, there have been various developments taken place in the field newlineof conducting polymers for different applications. Several studies have been newlineperformed to improve the gas sensitivities of various conducting polymers and their newlinecomposites workable at room temperature. Among all the conducting polymers, newlinepolyaniline has more importance than other conducting polymers because of its newlinedifferent inimitable properties, viz., better stability, the lightweight, successful newlinecombination of physical and chemical properties, better optical and electrical newlineproperties, etc. Binary semiconducting spinel ferrite has good electrical conductivity newlineand gas sensing ability because of its low density and larger surface area than single newlineoxide semiconducting materials. There are many improvements taking place in the newlinefield of polyaniline nanocomposites, that leads towards the development of newlinehigh-performance electrical and gas sensing materials operating at room temperature. newlineThe hybrid materials of PANI nanocomposites show good electrical properties with newlinelower dielectric losses, enhanced sensitivity, selectivity, and stability compared to the newlineindividual compounds. These nanocomposites have received greater attention for the newlinepast decades because of their exciting tailoring abilities in the structural modifications newlineand promising applications in many fields. newlineIn the present research work, a simple and cost-effective method was adopted newlineto synthesize the pure PANI-Ferrite nanocomposites by keeping the above facts in newlineview. PANI-Ferrite nanocomposites were prepared by in situ polymerization method. newlineThe prepared samples were characterized by thermo gravimetric analysis, newlineX-ray diffractometer, Fourier transform infrared spectrometer, Field emission newlinescanning electron microscope, energy dispersive X-ray analysis, and UV-Visible newlinespectrophotometer.
