Abstract
The need for sustainable and environmentally friendly alternatives to petrol-based plastics motivated the development of layered silicate nanocomposite films based on corn starch (CS) and bentonite nanoclay and plasticized with glycerol. The CS film was elastomeric with extensibility in uniaxial deformation of ca. 90% and with glass transition temperature at Tg = − 75 °C. The nanocomposites with well-dispersed bentonite exhibited an intercalated morphology at bentonite content of 3 wt%. Interestingly, bentonite reduced the Tg to − 80 °C, while increasing the Young’s modulus E and slightly reducing the extensibility. These results provide insights into the development of biodegradable food packaging and coatings at sub-ambient, freezing conditions.
