Abstract

Characterization of biodegradable polymers made from polylactic acid derived from tuber starches such as cassava and otoe, reinforced with yerba mate nanoparticles. Abstract– The development of materials based on natural resources has gained significant attention in recent decades due to their potential to provide sustainable alternatives for reducing environmental pollution. Currently, biodegradable polymers derived from natural starches are used in the production of single-use products. This research focuses on the characterization of biodegradable polymers made from polylactic acid derived from the starch of Panamanian tubers, such as cassava and otoe, reinforced with yerba mate nanoparticles. Various tests, including water vapor permeability, thermogravimetric analysis, tensile testing, and biodegradation assessment, were conducted. To achieve this, bioplastic sheets were fabricated using the solvent-casting technique. The starch-based polymer matrix was plasticized with glycerol at 25% (AL1) and 35% (AL2) w/w, and the glycerol-plasticized composition with 25% glycerol was reinforced with 1% (AL3) w/w yerba mate nanoparticles. The results, when evaluated and analyzed, demonstrate the functionality of the studied compositions, as they exhibit notable strength and biodegradability, offering a viable solution to produce products made from natural sources.
