Abstract
Transparent PANI-SiO 2 conducting films were prepared by hybrid of dodecylbenzene sulfonic acid-doped polyaniline (DBSA-PANI) and 3-glycidoxypropyltrimethoxysilane (GPTMS) through sol–gel route. The influence of content of DBSA-PANI on the structural, electrical and optical properties of the films was investigated. Sheet resistance of the hybrid films was 5.1 kΩ/□ and visible light transmittance was 75%, when the content of DBSA-PANI was 30 wt.%. Thermogravimetric analysis (TG) showed that the obtained films were thermally stable under 120 °C and optical bandgap of the hybrid films was determined from Tauc plots.
