Abstract

Biodegradable material was prepared from cassava starch in combination with zinc oxide nanoparticles (ZnO NPs) to give the properties of microbial growth resistance, glycerin concentrations were varied to 5%, 10%, and 20% (w/v) for the study of the rheological properties. The nanoparticles were characterized by a spectrophotometer where an exciton peak at 370 nm was obtained. The different samples were subjected to a thermomechanical study through an AR-G2 hybrid rheometer, using a parallel plane geometry of 20 mm, a weak gel behavior is observed, it is a slimming material and it is thermostable, it is also established that the zinc oxide concentration nanoparticles do not affect the mechanical behavior of the material.
