摘要

In present work, Dextran-grafted poly(acrylic acid) [D-g-PAA] hybrid nanocomposites are prepared in aqueous medium with reinforcement of various concentrations of nano-CaCO3 (CC) through in situ polymerization of acrylic acid. The chemical interactions between filler and polymeric matrix are studied by Fourier transform infrared spectroscopy. The structural properties of the D-g-PAA/CC nanocomposite are investigated by X-ray diffraction, field-emission scanning electron microscopy, and high-resolution transmission electron microscopy. The aloe vera plant structured morphology is noticed by interaction of dextran with PAA, where CC nanoparticles are embedded within the D-g-PAA matrix. The thermal stability of the D-g-PAA/CC hybrid nanocomposites is enhanced by the incorporation of nano-CC. The tensile properties and antibacterial behavior of D-g-PAA/CC hybrid nanocomposites are also increased by incorporation of nano-CC. The oxygen barrier behavior of hybrid nanocomposites is increased by 11-folds with a reinforcement of 8 wt % of nano-CC. Herein, the incorporation of nano-CC enhances the oxygen barrier, thermal, and antimicrobial properties of the D-g-PAA matrix by which the synthesized material is suitable for packaging applications.
