PVC-supported SP composite membrane: its synthesis, physicochemical, and electrochemical characterization

Polyvinyl chloride (PVC)-supported stannous phosphate (SP) is a newly synthesized composite material used to make porous, mechanically, and thermally stable composite membrane. Such composite membranes have been prepared by the mixing of organic and inorganic materials, and it shows a lot of applications in the field of purification and filtration technologies. The composite material and designed membrane have been characterized and identified on the basis of their chemical composition, ion exchange capacity, x-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric (TGA) plus differential thermal (DTA) analysis, and scanning electron microscopy (SEM). The characterizations and analysis demonstrated the functional groups, material nature, thermal stability, surface structure, porosity, elemental percentages, ion transportation, etc. Teorell Meyer and Seviers (TMS) theoretical approach is used to obtain the various important electrochemical parameters of membrane-like charge density, transport number, mobility ratio, charge effectiveness, etc.
