Resumen
La nanotecnología brinda la posibilidad de sintetizar nanomateriales como los nanotubos de carbono de pared múltiple (MWCNT’s), que permiten a un bajo costo, ser producidos y decorados con recubrimientos de nano-partículas para luego ser dispersados como aditivos en aceites de origen vegetal. Estas modificaciones se realizan para mejorar la biodegradabilidad de los lubricantes y estabilizar sus propiedades térmicas y químicas, con el propósito de mejorar su comportamiento reológico.
Se describe todos los ensayos, metodologías y resultados que permitieron obtener un lubricante de origen ve-getal aditivado, para lo cual, se sintetizaron, purificaron y funcionalizaron nanotubos de carbono de pared múltiple (MWCNT’s) para su posterior decoración mediante un recubrimiento superficial con disulfuro de molibdeno (MWCNT’s/MoS2) empleando la técnica de síntesis hidrotermal. Las nanoestructuras desarrolladas fueron caracterizadas por: SEM, TEM, FTIR, EDX, XRD, XPS y Raman. Posteriormente los MWCNT’s/MoS2 se dispersaron en aceite de palma refinado (AP), para luego evaluar sus propiedades mediante pruebas reológicas.
Nanotechnology offers the possibility of synthesizing nanomaterials such as multi-walled carbon nanotubes (MWCNTs), which allow them to be produced and decorated with nanoparticle coatings at a low cost and then dispersed as additives in oils of plant origin. These modifications are made to improve the biodegradability of lubricants and stabilize their thermal and chemical properties, with the purpose of improving their rheological behavior. All the tests, methodologies and results that allowed obtaining an additive lubricant of vegetable origin are described, for which multi-walled carbon nanotubes (MWCNT's) were synthesized, purified and functionalized for subsequent decoration by means of a surface coating with disulfide of molybdenum (MWCNT's/MoS2) using the hydrothermal synthesis technique. The developed nanostructures were characterized by: SEM, TEM, FTIR, EDX, XRD, XPS and Raman. Subsequently, the MWCNT's/MoS2 were dispersed in refined palm oil (PA), to then evaluate their properties through rheological tests.
