REINFORCEMENT OF ANTIMICROBIAL ACTIVITY AND SWELLING ABILITY OF STARCH-G-POLY 4-ACRYLAMIDOBENZOIC ACID USING CHITOSAN NANOPARTICLES
Source abstract
Abstract
New nanocomposites, denoted as St-g-P4ABA/CSNPs1% and St-g-P4ABA/CSNPs3%, were created by combining starch-grafted polyacrylamide benzoic acid (St-g-P4ABA) with chitosan nanoparticles (CSNPs) (1% and 3% based on graft weight). Nuclear magnetic resonance (1H NMR), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction were used to clarify the successful synthesis of the nanocomposite. The thermal stability of St-g-P4ABA copolymer and its degree of swellability in both water and 0.9% saline solutions significantly improved as a result of the incorporation of CSNPs, most notably in the saline solution. When compared to St-g-P4ABA, the St-g-P4ABA/CSNP composites showed better antibacterial activity against Gram-positive bacteria, Gram-negative bacteria and fungi.
