• W3201655879 abstract "A great effort is exercised to enhance the shelf life and at the same time to reduce waste accumulation, a new strategy is developed to explore eco-friendly packaging materials from renewable resources [1]. Therefore,the new era is focusing on research and development of biodegradable nanocomposites for food packaging to improve functional and barrier properties with the incorporation of nanoparticles into biodegradable polymers [2-4]. Nanoparticles due to their largesurface area and high surface energy have better interfacial interactions with functional groups on the polymer backbone, which significantly enhance the functional properties of the nanocomposites. Since packaging material interacts with food and acts as a barrier to the external environment, active packaging is achieved by inserting active compounds such as antimicrobials,antioxidants, UV-absorbers etc. into the polymer matrix [5-7].Antimicrobial active packaging provides an intrinsic methodology to control the growth of food spoiling microorganisms and enhance shelf life of the food products[8]. Among the nanoparticles, ZnO nanoparticles were non-toxic, highly stable and possess antimicrobial activity[9, 10]. Therefore incorporation of nanostructured ZnO into a synthetic and biodegradable polymer such as poly(vinyl alcohol) (PVA) is a feasible technique to enhance the antimicrobial property of the nanocomposite films [11]. Further cetrimide was added to improve the performance and antimicrobial property of the nanocomposite films. With this fact in view, the present work contributes cost-effective and green synthesis of the ZnO nanoparticles using Ayapana triplinervis plant extract. The obtained ZnO nanoparticles were characterized by an analytical technique such as SEM,XRD and FTIR. Analysis of the micro structure of ZnO nanoparticles revealed formation of hexagonal shaped particles with size ranging from 32-47 nm. Poly(vinyl alcohol)(PVA)/cetrimide(CT)/ZnO NPs (PCZ) nanocomposite films were prepared by varying concentrations of ZnO nanoparticles with fixed concentrations of PVA and cetrimide. The solvent casting method was employed to prepare nanocomposites using glutaraldehyde as a crosslinking agent. Further mechanical, physical, thermal and structural properties of the PCZ nanocomposites wereanalysed.DSC analysis suggested a decrease in heat of fusion for PCZ nanocomposite films, indicating an increased level of crosslinking. Improved thermal stability was observed with the increase in ZnO nanoparticle content in the nanocomposites. The XRD analysis depicted the appearance of some additional peaks along with main peaks, relating to structural deformation that occurred during the formation of PCZ nanocomposite and SEM analysis showed uniform distribution ofZnO nanoparticles in the polymer matrix. The addition of different weight percent of ZnO nanoparticles in PCZ nanocomposite films decreased the tensile strength but there was an increase in elongation at break compared to control poly(vinyl alcohol) (PVA)/cetrimide (CT) (PCZ-0) film. Moisture absorption, film opacity and hydrophobicity was slightly increased with the addition of ZnO nanoparticles to the polymer matrix. FTIR spectra revealed interactions among the components of nanocomposite films. PCZ nanocomposites have shown a decrease in the barrier properties and overall migration values were well within the acceptable limits. The prepared PCZ nanocomposites exhibited better antibacterial activity against Gram-positive bacteria (Staphylococcus aureus) as well as Gram-negative bacteria (Escherichia coli). With all these results, fabricated nanocomposites can find potential applications in packaging material to extend the shelf life of foodstuffs." @default.
