Abstract
The problems caused by synthetic waste have led to the need to develop new materials that can be environmentally safe for living organisms and biocompatible with the environment, replacing widely used synthetic polymers. IF spectroscopy was used to study the chemical composition of the composite and to detect harmful substances. The nature of the relationships of structural components in the compositions was studied using scanning electron microscopy. The impact strength was determined by the Charpy method. The nature of the interaction of system components at the microstructural level is investigated. In particular, the anisotropy of properties, which is ensured by the uniform distribution of cavities in the volume of the composite and good adhesion of microcellulose with casein binder, was investigated. It is established that the composite does not contain harmful, toxic substances and can be positioned as a biocomposite. This material has been shown to have sufficient impact characteristics, in particular, impact strength a = 47 kJ/m2 and can be used in the manufacture of food packaging, such as an alternative to polystyrene.
