Abstract

In the current work, EVA/PANI composite is successfully prepared by in-situ technique. Both prepared materials are characterized by XRD, FTIR, UV-Visible, and SEM analyses. Wettability and dielectric properties of both EVA film and EVA/PANI composite are studied. High intense peak is found in EVA/PANI composite and is indicated more crystalline nature compared to pristine EVA polymer film. π-π* and polaron transitions are appeared in the UV-Visible spectrum of EVA/PANI composite. Different absorption band of EVA film and EVA/PANI composite are viewed in their spectrum. A study has been made of wettability of smooth surfaces of EVA and HCl doped EVA/PANI materials by observing the equilibrium contact angle formed by a liquid drop resting on the solid surface. Wettability results of EVA/PANI composite shows hydrophilic nature. Frequency dependent AC electrical conductivity and Dielectric are analyzed for both materials.
