• Composite films
• ZnO-CuO nanopartides
• Terephthalic acid
• Disposed poly(ethylene terephthalate) oil bottles
• Biodegradable poly-epsilon-caprolactone

The present investigation describes the development of metal-oxide polymer nanocomposite films from biodegradable poly-epsilon-caprolactone, disposed poly(ethylene terephthalate) oil bottles monomer and zinc oxide-copper oxide nanoparticles. The terephthalic acid and zinc oxide-copper oxide nanoparticles were synthesized by using a temperature-dependent precipitation technique and double precipitation method, respectively. The terephthalic acid synthesized was confirmed by FTIR analysis and furthermore, it was characterized by thermal analysis. The as-prepared CuO-ZnO nanoparticles structure was confirmed by XRD analysis and its morphology was analyzed by SEM/EDS and TEM. Furthermore, the metal-oxide polymer nanocomposite films have excellent mechanical properties, with tensile strength and modulus better than pure films. The metal-oxide polymer nanocomposite films that were successfully developed show a relatively brighter colour when compared to CuO film. These new metal-oxide polymer nanocomposite films can replace many non-degradable plastics. The new metal oxide polymer nanocomposite films developed are envisaged to be suitable for use in industrial and domestic packaging applications.
