Incidencia del óxido de grafeno en las propiedades mecánicas de las láminas de plástico biodegradable de oca (Oxalis tuberosa)

Abstract

The aim of this research was to verify the impact of graphene oxide on the mechanical properties of biodegradable plastic sheets from Oca (Oxalis tuberosa). Firstly, starch was obtained through the wet process with the best yield and characterized according to the standards established by the FAO (Food and Agriculture Organization of the United Nations), which made it possible to identify its suitability for the production of biodegradable plastic sheets. On the other hand, the synthesis of graphene oxide was carried out with a yield of 84.93%. A totally randomized factorial design was used to identify the optimum volume of addition of the compound in the formulation of the biodegradable plastic sheet, where an evaluation of a total of six treatments was obtained. To evaluate the product obtained, physical and mechanical tests were carried out, where the thickness was less than or equal to 0.12 mm and the maximum displacement was 10.36 cm for treatment six. Finally, the tests were carried out in three different environments, where the maximum degradation in soil was 31.85%, in a time of 15 days, which is within the established limit, in water 8.32% and in environment 12.45%, therefore, when studying the results, the improvement in the mechanical properties of the biodegradable plastic sheets is verified. It is recommended to analyze the application of different additives to improve the mechanical properties according to their use.
