Synthesis, characterization and electrochemical observation of PVC based ZMP composite porous membrane and its physicochemical studies by applying some strong electrolytes through TMS equation

Abstract

PVC based zinc molybdophosphate (ZMP) has been synthesized via sol gel method of material synthesis, which is used to design a mechanically stable organic-inorganic composite membrane. The composite material plus membrane has been characterized by using various sophisticated techniques like x-ray diffraction, fourier transforms infrared spectroscopy, scanning electron microscopy, thermo gravimetric/differential thermal analysis and simultaneously potentiometer analysis also. The characterizations confirmed that there is a strong interaction found between PVC and ZMP particles and the resulting composite has indicated higher thermal stability than the pure material. It also demonstrated the material nature, functional groups, surface structure, thermal stability, porosity, and ion transportation etc. Teorell, Meyer, and Sievers (TMS) theoretical approach is used to explain the various electrochemical applications of membrane like charge density, transport number, mobility ratio, charge effectiveness etc. Some strong electrolytes like KCl, NaCl and LiCl are used to explain the membrane behavior which has been confirmed by observing the ionic potential and charge density of membrane.
