Title:

METHOD FOR MANUFACTURING A NANOFLUID CONTAINING CARBON NANOPARTICLES TREATED WITH METAL

Document Type and Number:

WIPO Patent Application WO/2012/144679

Kind Code:

A1

Abstract:

The present invention relates to a method for manufacturing a nanofluid containing carbon nanoparticles treated with metal, said nanofluid being useful for heat-exchangers and all industries in which lubricating properties are required. The method for manufacturing the nanofluid containing carbon nanoparticles treated with metal includes: a step of milling a carbonaceous material; a step of acidizing the surfaces of the carbon nanoparticles resulting from the milling step; a step of drying the carbon nanoparticles resulting from the acidizing step; a step of heat-treating the carbon nanoparticles resulting from the drying step; and a step of mixing the carbon nanoparticles resulting from the heat-treatment using a metal hydroxide solution, and irradiating the carbon nanoparticles with ultrasonic waves.
