Abstract

The invention belongs to the technical field of modified inorganic nanometer functional materials and discloses a novel nano-fluid and its preparation method and an application thereof. The preparation method comprises the following specific steps: dissolving inorganic nanoparticles in water, adjusting pH to alkaline by adding alkali, carrying out ultrasound, adding the inorganic nanoparticle solution into a silane coupling agent ethanol solution to react for 4-48h so as to obtain a nanoparticle solution containing epoxy functional groups; adding tertiary amine and hydrochloric acid to react for 1-48h, adding polyoxyethylene ether sulfonate to react for 1-48h, and purifying to obtain the novel nano-fluid. The novel nano-fluid is a fluid-like shape. Processability of nanoparticles is raised. The novel nano-fluid also can be used as a special solvent and a reaction medium. The preparation method is simple and easy to operate. Modified nanoparticles will not be agglomerated. Physicochemical properties of nanoparticle kernel are still retained, and nano-fluids with different properties can be obtained by adjusting the type of inorganic nanoparticles and polymerization degree of polyoxyethylene ether sulfonate.

Description

technical field

[0001] The invention belongs to the technical field of modified inorganic nanometer functional materials, and in particular relates to a novel nanofluid and its preparation method and application. Background technique

[0002] Nano-inorganic particles have excellent special properties such as light, force, electricity, heat, magnetism, radiation, and absorption. They have unique characteristics in many disciplines and fields and play an irreplaceable role. Large, very easy to agglomerate, the dispersion stability of the particles must be improved through surface modification. The surface modification of inorganic nanoparticles can be divided into two categories: surface chemical modification and physical modification. Physical modification makes the particles difficult to agglomerate by adsorbing surfactants on the surface of inorganic particles. However, research and practice have shown that the grafted amount of high molecular organic matter on the surface...
