The study of the structure and properties of nanostructured biodegradable thermoplastic composite

Increased requirements for polymer materials and the expansion of their application fields create the prerequisites for the creation of new composite materials. The most promising matrix for the biocomposite material is 2-hydroxypropionic (lactic) acid, the unique capabilities of which are manifested as a result of modification by inorganic mineral fillers of nanometric size. The combination of such properties as Biodegradability and biocompatibility is particularly valuable in this polymer. Nanostructured composite materials, consisting of polylactic acid and mineral fillers, acquire a significant improvement in properties compared to the properties of a pure polymer. Biodegradable films containing a layered natural mineral from the class of metasilicates were obtained by the method of irrigation of molding solutions. Trichloromethane was used as a solvent for the preparation of molding solution. The structure and properties of a nanostructured thermoplastic composite are studied...
