“…Since the absorption of oxygen is significantly higher than for pure EC films, the transmission rate is expected to be lower. Since incorporating TiO 2 nanoparticles is highly beneficial for the gas and water transmission rate and, as reported recently, has impressive antibacterial properties [30][31][32], this simple process of preparing EC films with incorporated nanoparticles shows high potential in active food packaging.…”

In this research, ethyl cellulose films were prepared by a simple, easy, controlled one-pot method using either ethanol or ethyl lactate as solvents, the films being formed at 6 °C. Titanium dioxide nanoparticles were incorporated to improve the oxygen transmission and water vapour transmission rates of the obtained films. This method used no plasticizers, and flexible materials with good mechanical properties were obtained. The resulting solvent-free and transparent ethyl cellulose films exhibited good mechanical properties and unique free-shapable properties. The obtained materials had similar properties to those reported in the literature, where plasticizers were incorporated into ethyl cellulose films with an elastic modulus of 528 MPa. Contact angles showed the hydrophobic nature of all the prepared materials, with contact angles between 80 and 108°. Micrographs showed the smooth surfaces of the prepared samples and porous intersections with honeycomb-like structures. The oxygen and water vapor transmission rates were the lowest for the ethyl cellulose films prepared in ethyl lactate, these being 615 cm3·m−2·day−1 and 7.8 gm−2·day−1, respectively, showing that the films have promise for food packaging applications.

An antibacterial biobased compound emulsion was prepared by modifying cationic oxidized starch grafted styrene‐acrylic emulsion with 3 – (trimethoxysilyl) – propyldimethyloctadecyl ammonium chloride (AEM5700) and tea polyphenols. The biobased compound emulsion exhibited better stability, chemical properties and antibacterial properties. The structure and surface morphology of biobased compound emulsion were characterized by Fourier Transform infrared spectroscopy (FTIR) and Transmission electron microscopy (TEM). The thermal stability of biobased compound emulsion was improved, which can be concluded from the thermogravimetric analysis (TGA). The surface morphology of film was observed by the atomic force microscope (AFM). The wetting property of emulsion film was tested by contact angle test. When the compound ratio was 1.5, the biobased antibacterial compound emulsion had better stability and antibacterial properties. Compared to a single antibacterial agent, the inhibition zone increased by 4–5.5 mm. In addition, the polymerization mechanism of the biobased antibacterial emulsion was analyzed.This article is protected by copyright. All rights reserved
