Spectroscopic, thermal and sorption characterization of poly(vinyl alcohol)-borax hydrogels with incorporated turmeric
In this work, three sets of poly(vinyl alcohol) hydrogels, cross-linked using borax, with incorporated turmeric have been synthesized. Their water content, spectroscopic, thermal and sorption properties have been studied, as functions of borax and turmeric concentrations. The water content of the hydrogels decreases due to the presence of turmeric. The Fourier Transform Infra-red (FT-IR) and Raman spectroscopic measurements confirm the incorporation of turmeric in the matrices. Turmeric does not chemically bond with the polymer hydrogel network but is confined to the solvent phase within the pores. The presence and concentration of turmeric significantly affect the adsorption of water molecules onto the polymer backbone. Glass transition temperature and solvent uptake are affected by the concentration of borax and turmeric in the matrices. The sorption behaviour obeys the second-order kinetic model. The observed modifications in properties are caused by the structural re-arrangement of the polymer chains and the re-organization of borate cross-links due to the presence of turmeric.
期刊介绍:
Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology.
As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including:
polymer synthesis;
polymer reactions;
polymerization kinetics;
polymer physics;
morphology;
structure-property relationships;
polymer analysis and characterization;
physical and mechanical properties;
electrical and optical properties;
polymer processing and rheology;
application of polymers;
supramolecular science of polymers;
polymer composites.
