INFLUENCE OF ALUM-DES ON SOME PROPERTIES OF PVA

Abstract

Deep eutectic solvents DES as a type of Ionic Liquid IL have caught the great attention of many researchers in different applied fields. One of these fields is their effect on polymer preparation to enhance their thermal, mechanical or conductivity. In this work, Alum as deep eutectic solvents DES were used to study its influence on Polyvinyl alcohol PVA polymer properties. The interaction between the deep eutectic solvents DES and PVA was tested by ATR-IR, where the polymer was found to contain the DES within the PVA structure. SEM micrographs for the pure PVA show clearly that this polymer's morphology is a uniform type but with different degrees of rough surface morphology. In contrast, the PVA-DES system shows aggregates or chunks of Alum on the top surface of the membrane.
