Greener Synthesized Copper Nanoparticles incorporated in Polyethylene Glycol/ Polyvinyl Alcohol Nanocomposite for Food Package Applications

Green Synthesis of nanoparticles enables for medical and Food package applications. Copper nanoparticles (CuNPs) are having antimicrobial and anti-viral properties that provides the cushion in drug delivery applications. Green Synthesis of copper nanoparticle from Capparis zeylanica plant and solution casting it with Polyethylene Glycol/Polyvinyl Alcohol can be utilized for food packaging, drug delivery and cancer therapy, etc. Capparis zeylanica plant extract act as both reducing and stabilizing agent on the outermost layer of copper nanoparticles. The synthesized nanoparticles and nanocomposite were characterized and found to be of 65 nm of particle size using scanning electron microscopy. Fourier transform infrared spectroscopy shows the presence of various bio-active materials that were responsible for the stabilization of CuNPs. Differential Scanning Calorimentric studies on the composites shows that there a significant increment in the glass transition and melting temperature of the composites of +10 oC with that of the polymer blend. Moisture absorption and Anti-microbial analysis were carried out to understand the stability of the nanocomposites. Polyethylene Glycol/Polyvinyl Alcohol + Copper nanoparticles nanocomposite shows an excellent characteristic in most aspect that able to fit for bio-medical and food packaging applications.
