Abstract

The invention discloses an ion nanometer material with fluid behavior at the room temperature and a preparation method thereof. The ion nanometer material comprises the following components in percentage by weight: 15-35% of nanoparticle, 20-30% of functional ion liquid and 5-60% of fatty alcohol-polyoxyethylene ether sulphonate. In the ion nanometer material, the surface of the inorganic nanoparticle is grafted with organic-inorganic hybridized nanometer material of organic long chain polymer with an ion pair structure, wherein the nanoparticle content is above 15wt%; and under the condition of no solvent, the ion nanometer material is viscous liquid and has the fluid behavior. The ion nanometer material with fluid behavior at the room temperature is simple to prepare and operate and is easy to realize. Because of good dispersibility, heat stability and fluidity under low vapour pressure, the ion nanometer material with fluid behavior at the room temperature has a potential application prospect on the aspects on enhancing strength, toughness and the like for lubricant, plasticizer, film formation precursor, new energy and polymer matrix composite material.

Description

technical field [0001] The invention relates to an ion nanomaterial with fluid behavior at room temperature and a preparation method thereof. Background technique [0002] With the development of nanotechnology, it is now possible to precisely control the chemical structure, morphology, particle size, and distribution of nanoparticles. However, because the agglomeration of nanoparticles hinders the industrial application of nanoparticles, it is necessary to modify the surface of nanoparticles to improve the dispersion stability of nanoparticles. Usually the surface modification of nanoparticles, at room temperature or low temperature, nanoparticles are solid, so in some fields, such as heat transfer fluid and self-assembly, nanoparticles must be added with a solvent to use, and the solvent content sometimes reaches 60% The above not only waste resources and pollute the environment, but also greatly limit the application field. Therefore, it is undoubtedly of great advantag...
