The Influence of SnO2 Nanoparticles on Electrical Conductivity, and Transmittance of PANI-SnO2 Films

Abstract

The study of the potency of conductive polymer and its combination with a various dopant of metals, oxides, and other radicals is significantly improved. We report the results of the study to determine the effect of SnO2 addition on the microstructure, absorbance, and electric conductivity of PANI-SnO2 films. In this work, we also report the effect of variations of light intensity on its electrical conductivity of the same films. The results showed that the addition of mass SnO2 affecting the structure of the PANI-SnO2 bonding function group in which indicated by the appearance of Sn-O-Sn peak at the wave number of 601.79 cm-1. The addition of SnO2 affects the crystallinity ratio of PANI-SnO2 films shown by the crystallinity of PANI-SnO2 films by 53.16 %. The addition of SnO2 reduces the porosity of morphological shape of the PANI-SnO2 film surface. It is surprising that addition of mass SnO2significantly increases the electric conductivity of PANI-SnO2 films by (4.24 × 102) S•cm-1. The addition of SnO2 increases the transmission by 35.48 %. Light irradiance on PANI-SnO2 film decreases the conductivity of the PANI-SnO2 film.
