Abstract

Poly(ethylene furanoate) (PEF) biocomposite films incorporating zinc oxide nanoparticle (ZnO NPs) were prepared using a solvent casting method. The ZnO NPs were homogeneously dispersed within the PEF films with the aid of γ−aminopropyltriethoxylsilane (APTES). The water vapor barrier, optical transmittance and antimicrobial properties of the PEF/ZnO films were tested. Water vapor permeability (WVP) and transmittance in the visible (400–800 nm) region of control PEF film were 6.92 × 10–12 g·m m−2 · s·Pa and 87.3%, respectively. WVP value of PEF films decreased 43.2% through ZnO NPs compounding. On the contrary, transmittance of PEF films decreased 6.8% due to the absorption and scattering of ZnO NPs. In addition, the PEF film with modified ZnO NPs exhibited a bacteriostatic rate up to 97.0% after 3 h. Thus, the PEF/ZnO films show great potential in the field of food packaging.
