Incidencia de la adición del óxido de grafeno en la obtención del plástico biodegradable de la malanga (Colocasia Esculenta) con sus propiedades mecánicas

Abstract

The demand for bioplastics currently does not represent a serious competition for the market of synthetic plastics, since the latter are more aggressive to the environment. The objective of this research work is to analyze to extent the mechanical properties of bioplastics formed from taro starch improve through the use of different treatments with graphene oxide in order to allow progress in future studies on the addition of graphene as a complementary additive. The methodology implemented is based on both a quantitative and qualitative approach, it was also used in an experimental design by varying the independent variable (graphene oxide); the study population is the raw material of taro which was subjected to methods and techniques for its characterization and obtaining starch, being important a documentary and field study for the synthesis of graphene oxide (GO) by the modified Hummers method and its respective addition to the bioplastics produced. By means of mechanical tests, it was determined that there is indeed a considerable increase in properties such as elastic modulus, maximum load, maximum displacement, maximum stress, maximum deformation and load rupture. On the other hand, properties such as biodegradation are not affected. Thus, it was concluded that the best treatment for future applications in the industry corresponds to TBM2 since it showed good results in mechanical properties and the best results for maximum deformation and maximum displacement.
