properties

Composite films were obtained from a mixture of starch, polyvinyl alcohol, and a plasticizing additive based on aspartic acid. The surface morphology, structural features of the composites, and their behavior in a polythermic mode were studied by scanning electron microscopy, X-ray diffractometry, IR spectroscopy, differential thermal and thermogravimetric analysis. Only carbon dioxide was detected in the gaseous products of thermal decomposition of the samples. The sorption and physico-mechanical properties of our composite films were analyzed.

A method is proposed for obtaining a promising cellulosecontaining oil sorbent based on the buckwheat shell and millet shell, suggesting its modification by compounds structuring the polymer followed by heat treatment. These modification methods contribute to the creation of carbon structures with controlled porosity, as well as an increase in the yield of carbonized structures after heat treatment. Sorption properties of materials based on modified plant raw materials are investigated.
