Summary:The present invention relates to a manufacturing process of bionanocompounds based on molten thermoplastic starch with graphene oxide, which consists of 4 steps: A) dispersing and exfoliating the OG in water, B) formulating a granular starch paste and a plasticizer, C) mechanically mixing A and B and left to stand for at least 8 h, D) thermoplasticizing (C) in the molten state. By means of this process, the bio-nanocomposites with exfoliated graphene oxide are obtained, which present mechanical properties with high performance compared to thermoplastic starch. This process includes the advantage of being easily implemented on an industrial scale and the bio-nanocomposites obtained therefrom, can be used to replace some synthetic polymers in the automotive, agricultural, energy, packaging and construction industries, among others. La presente invención es un proceso que se refiere a elaborar bionanocompuestos a base de almidón termoplástico con óxido de grafeno en el estado fundido, que consta de 4 etapas: A) dispersar y exfoliar el OG en agua, B) formular una pasta de almidón granular y un plastificante, C) mezclar mecánicamente A y B y dejar reposar por al menos 8 h, D) termoplastificar C en el estado fundido. Mediante este proceso se obtienen los bionanocompuestos con óxido de grafeno exfoliado los cuales presentan propiedades mecánicas con alto desempeño en relación al almidón termoplástico. Este proceso tiene la ventaja de implementarse fácilmente a escala industrial y los bionanocompuestos obtenidos pueden ser utilizados para sustituir algunos polímeros sintéticos en la industria automotriz, agrícola, energética, embalaje, construcción, entre otras.
