dc.description.abstractNanofluids are colloidal suspensions of nanoparticles in a base fluid, which are being widely studied searching improvements in thermophysical properties that they present in relation to the base fluid. In this work, graphene and multi-walled carbon nanotubes (MWCNT) were modified superficially with carboxyl and amino functional groups, through oxidation with nitric and sulfuric acid to generate the carboxyl groups, later, these were treated with 2-(2-aminoethoxy)ethanol to generate the amino group. Then, the modified carbonaceous materials were structurally, thermally and morphologically characterized by means of infrared spectroscopy with Fourier transform (FT-IR), Raman, thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) ; obtaining as a result, the presence of carboxyl and amino groups on the surface of the materials, without affecting its structure. Next, using the two-step method, nanofluids of each functionalized and un-functionalized material were prepared at 0.1% w/w of nanomaterial and water as the base fluid; in the case of graphene and MWCNT without functionalizing the surfactant was used sodium dodecylbenzene sulphonate (SDBS) as a dispersing agent at 0.5 and 1.0 respecting critical micellar concentration (cmc). Lastly, each nanofluid is evaluated for stability by visual inspection, UV-Vis and zeta potential, giving as result that nanofluids of MWCNT functionalized and with surfactant are the most stable, remaining in suspension for thirty days. Finally, the thermal conductivity of the nanofluids was determined by the technique of the transient hot wire, obtaining for the nanofluid of MWCNT functionalized with carboxyl a maximum increment of 12.94% in the thermal conductivity respect to water.spa

En este trabajo se modificaron superficialmente grafeno y nanotubos de carbono de paredes múltiples (MWCNT) con grupos funcionales carboxilo y amino, por medio de una oxidación con ácido nítrico y sulfúrico para generar los grupos carboxilos y posteriormente tratarlos con 2-(2-aminoetoxi)etanol para generar el grupo amino. Después los materiales carbonosos modificados se caracterizaron estructural, térmica y morfológicamente por medio de espectroscopía infrarroja con transformada de Fourier (FT-IR), Raman, análisis termogravimétrico (TGA), microscopía electrónica de barrido (SEM) y microscopía electrónica de transmisión (TEM); obteniendo como resultado, la presencia de grupos carboxilo y amino en la superficie de los materiales, sin afectar la estructura de los mismos. Luego usando el método de dos pasos, se procedió a preparar nanofluidos de cada material funcionalizado y sin funcionalizar a una concentración de 0,1% en peso de nanomaterial y agua como fluido base; en el caso del grafeno y MWCNT sin funcionalizar se usó el tensoactivo dodecilbenceno sulfonato sódico (SDBS) como agente dispersor a 0,5 y 1,0 respecto a la concentración micelar crítica (cmc). Finalmente, cada nanofluido se le evalúa la estabilidad por medio de inspección visual, UV-Vis y potencial zeta, siendo el resultado de estas pruebas que los nanofluidos de MWCNT funcionalizados y con tensoactivo son los más estables, manteniéndose en suspensión por treinta días. Finalmente se determinó la conductividad térmica de los nanofluidos por la técnica del hilo caliente transitorio, obteniéndose para el nanofluido de MWCNT funcionalizado con carboxilo un aumento máximo en la conductividad térmica de 12,94% respecto al agua.spa
