Resumen

This paper presents the study of the effect of the incorporation of biosynthesized silver nanoparticles on the properties of biodegradable films made from potato starch and its potential to be used as active material. Silver nanoparticles were manufactured by green route from grape residues and were added in the film gelatinization process at concentrations of 3% and 6% v/v. The silver nanoparticles were characterized by UV-Vis and FTIR spectroscopy, while the fabric films were characterized by their density and % moisture content. Active properties were characterized using water absorption kinetics and biodegradation by burial in soil. The integration of silver nanoparticles in biodegradable films made from potato starch was confirmed, confirming the effects on their physical characteristics and active properties depending on the percentage of agNp, which can be used for the manufacture of active materials.
