The effect of Radiation on Thermal conductivity of Nano-Structured PANI/Bi2Te3 Composites.
Nano-structured Bi2Te3, Polyaniline (PANI) and PANI/ Bi2Te3 were synthesized by Solvothermal method. The crystallite size, Strain, inter-chain separation and unit cell volume were calculated from the X-ray diffraction (XRD) results by using Win fit and Unit cell software. The Gamma irradiation (γ-rays) with dose 50 KGy affects the peaks positions for the PANI samples whereas; it affects the intensity of Bi2Te3 samples. Thermal conductivity measurements were investigated from the differential scanning calorimeter (DSC) with respect to Indium (In) melting temperature curve. 50 KGy dose does not show a remarkable change in the PANI and PANI/ Bi2Te3 values on contrast the value of Bi2Te3 sample was reduced.
