Abstract
In our present work an attempt has been made to investigate as to how the variation in the filler(ZnO NPs) concentration affects the electrical and thermal properties of the polymer nanocomposite. The morphology of PANI and PANI-ZnO nanocomposite was analysed using SEM and TEM.. SEM analysis of ZnO showed a size distribution of 50-70 nm. Thermogravimetric analysis shows the change in decomposition temperature of the polymer. Hall effect study shows the decrease in carrier concentration in composite as compared to pure PANI. The hall voltages have been found to be negative indicating that the dopant polyaniline behave like a n-type semiconductor. The Hall coefficient(RH) and carrier concentration(n) have been determined from Hall measurements. Main objective of the present work is Hall effect studies on polymer nanocomposites and their heterostructure.
