Features of Structure and Properties of Biopolymer Composites with Inorganic Nanoparticles

摘要

The morphology, atomic structure, and strength characteristics of composites of barium titanate and silicon dioxide nanoparticles with biopolymers (collagen, lignin, starch) were investigated. Both changes in the inner structures and oriented ordering of morphology were found in the composites of barium titanate with collagen. Formations of quasi-parallel rows from silicon dioxide nanoparticles were found in the collagen composites with silicon dioxide. Thermal resistance of the collagen increased significantly in the process. Formation of a three-dimensional periodic structure from spherical nanoparticles was found in the composites of silicon dioxide with lignin. Interaction mechanisms of nanoparticles and biopolymers causing formation of the observed structures are discussed.
