Investigate the Impact of Ni-Doped ZNO NPS on The Antibacterial Activity and Degradation Rate of Polyacrylic Acid-Modified Starch Nanocomposite

Abstract

The current work examines the effects of adding nickel-doped zinc oxide nanoparticles (Ni- Doped ZnO NPs) to materials that are polyacrylic acid-modified starch nanocomposite (PAA-Starch NC) on their antibacterial activity and rate of degradation. Although PAA-Starch is a biodegradable polymer with excellent water absorption & film-forming capabilities, it is not very efficient against bacteria and degrades slowly. In the production of PAA starch, ammonium persulfate was used as a free radical initiator, in conjunction with the biodegradable nonionic surfactant Dec oxyethylene n-decyl ether, commonly referred to as Lutensol-XL-100. In order to control the rate at which the composite plastic degrades, a nanocomposite (NC) was synthesized through the combination of Ni-Doped ZnO NPs with an optimized thin film of starch-based plastic. Several techniques, such as FTIR, TGA, DSC, & SEM, were used to characterize the NC. By increasing the composite film's heat resistance and inhibiting bacterial growth, ZnO@Ni NPs gave it antibacterial properties. After 60 days in soil, biodegradation of starch- grafted PAA was 23.21%, compared to 16.19% for its NC. The results of the antimicrobial tests on the composite film were outstanding.
