Abstract
Polyvinyl alcohol (PVA) is a fabulous, non-toxic, synthetic solvent swelling polymer having widespread novel applications for its biocompatible characteristics. However, water is an excellent solvent for PVA, except this, it is soluble in numerous polar, organic solvents such as DMSO, DMF, etc. The present study is associated with the synthesis of PVA polymeric membranes by using different solvents. The spectroscopic analysis both from density functional theory and experimental observations indicate the co-existence of solvents in the PVA polymeric membrane, where the solvents remain trapped inside the membrane and impossible to remove completely despite the application of higher temperature to the membrane, which helps to refute the basic concept of membrane technology of “solvent-free membrane” formation. The XRD patterns of membranes show a peculiar phase changing phenomenon after annealing the membranes at 125°C. The FTIR and Raman spectroscopic studies showed a comprehensive perception on solubilization mechanism for the preparation of PVA membrane in different solvents with the variation in annealing temperatures and provided information regarding the polymer-solvent interactions during the formation of the polymeric membrane. The SEM images show the beautiful fish scale-like (spherulite) surface morphologies of the synthesized PVA-membranes.
