Resumen de: CN120077086A
The invention provides a method for preparing a biodegradable polymer nano composite film. The film has excellent gas barrier property, tensile property and dimensional stability at the distillation temperature. The methods involve employing a one-step reactive mixing process to improve the interaction between biodegradable polymers and nanoparticles, including phyllosilicate nanoclays and metal organic frameworks (MOFs). The obtained nano composite film shows excellent gas barrier property, and has improved tensile strength and dimensional stability at distillation temperature. Various biodegradable polymers such as PBAT, PLA, PHA, PBS, PCL and PHBV can be used as a supporting outer layer of the nano-composite film, so that the nano-composite film has multiple purposes in application. The one-step reaction mixing method provides an economical and environment-friendly way for preparing the advanced biodegradable polymer nano composite film.
