Abstract
A biodegradable composite material which is produced by polymerizing a mixture of an aqueous dispersion of a natural polymer nanofiber including any one or more of a chitin nanofiber and a cellulose nanofiber, a dicarboxylic acid or a derivative thereof, and a diol. The biodegradable composite material has excellent biodegradable and mechanical properties.
