Synthèse et caractérisation d’un composite hybride « Polymère/TiO2 »

Abstract

conductivity using Fourier Transform Infra-Red spectroscopy (IR-TF), X-ray Diffraction (XRD) and measurements of electrical conductivity. The results of IR-TF clearly confirm the polymerization of pyrrole and the incorporation of TiO2 into the structure of PPy. The DRX results show that the presence of TiO2 in the composite contributes to a change in the structure of the completely amorphous PPy to a well-developed crystalline structure, the electrical measurements indicate a decrease in the electrical conductivity of the PPy / TiO2 composite 10% compared to the Pure PPy, this decrease is perhaps due to the trapping of the charges present in the polymer by the titanium dioxide.
