Description
Summary:Polyaniline (PANI), one of the conductive polymers has been intensively studied. The PANI has practically used in electronic device, and gas sensor. However, the PANI based on the electronic device has weaknesses such as fragile, and unstable of conductivity at high temperature and in an acidic environment. This obstacle can be solved by inducing other better thermal properties materials. One kind of the materials that meet the criteria is TiO2. However, TiO2 has limitation due to the low conductivity compared to the conductivity of PANI. Theoretically, this problem can be solved by reducing the particles size of TiO2 down to nanometric size. In this study, we prepared a composite film with a various amount of nano TiO2 to obtain information related the microstructure, electrical conductivity, and their thermal stability. The results of FTIR spectra analysis showed that the PANI-TiO2 composites films were successfully synthesized which is indicated by the appearance of PANI and TiO2 characteristic bonds associated with the references. XRD spectra showed the increased crystallinity of PANI-TiO2 composite films along the addition of TiO2. The SEM images presented the decreasing porosity of the samples by increasing the TiO2 contents. Further, the conductivity of PANI-TiO2 composite films decreased by increasing the TiO2 nanoparticles. On the other hands, the thermal stability of the PANI composite films increased by increasing the TiO2 nanoparticles.
