On the theoretical study of the structure of a starch-based biopolymer

Abstract Biodegradable materials have lower production costs, they are easy to work with, and environmentally friendly too. Bioplastics can use natural organic wastes, such as nopal, sargassum, banana peel, corn, algae a variety of products. There is also the synthesis characterization these new bioplastics, however, very little known their electronic structure materials. This study analyzes interaction starch, fundamental basis biopolymer, with glycerol used plasticizer polyvinyl alcohol obtain using Density Functional Theory (DFT). The possible reaction mechanisms between starch (25% amylose 75% amylopectin) analyzed. PBE/Def2-TZVP theory level capable reproducing helical structures amylopectin.
