Enhanced Functional Properties of Biodegradable Polyvinyl Alcohol/Carboxymethyl Cellulose (PVA/CMC) Composite Films Reinforced with l-alanine Surface Modified CuO Nanorods

Herein, we described novel biogenic preparation of the CuO nanorods and its surface modification with l-alanine amino acid accelerated by microwave irradiation. The effect functionalized on physico-mechanical properties polyvinyl alcohol/carboxymethyl cellulose films were investigated through various characterization techniques. tensile strength was improved from 28.58 ± 0.73 to 43.40 0.93 MPa, UV shielding ability barrier water vapors highly enhanced when PVA/CMC matrices filled 8 wt% CuO-l-alanine. In addition, prepared exhibited acceptable overall migration limit readily undergoes soil burial degradation. Nevertheless, CuO-l-alanine incorporated showed potent antioxidant activity against DPPH radicals had high antibacterial Staphylococcus aureus Escherichia coli, antifungal Candida albicans tropicalis. Furthermore, nanocomposite negligible cytotoxic HEK293 Caco-2 cell lines. these contexts, developed can be implementing as an active food packaging material.
