Abstract
In this work, these alternate organic acids are blended into polyvinyl alcohol (PVA)-Starch (St) polymer composite to increase the cross-linking, plasticizing, and antibacterial capability of the polymer network. The most expensive of these three organic acids is TA, followed by MA and CA. The MA-based PVA composite films outperformed the CA-based PVA compo-site film in terms of absorbency (739.29%), mechanical strength (4.88 MPa), and elasticity (103.68%) among the three alternative organic acid-based PVA composite films. Furthermore, following a 24-hour incubation period, the MA-based films showed the highest proliferative effect of 215.59% for HEK cells. MA has been determined to be the most pertinent organic acid going forward to optimize the physical and biological properties, cost, and composition of the film.
