| titleOfInvention | Manufacturing method of nano-sized powder having excellent dispersibility and uniform particle size |
| abstract | The present invention synthesizes a nanopowder based on a coprecipitation method and a hydrothermal (or solvothermal) synthesis method, but (a) adding a basic material to the first nanoparticle precursor solution to adjust the pH to prepare a first nanoparticle precipitation solution ; (b) recovering the first nanoparticles after stirring by adding a surfactant to the first nanoparticle precipitation solution; (c) synthesizing second nanoparticles from the first nanoparticles; and (d) adding silane and a dispersing agent to the solution in which the second nanoparticles are dispersed and stirring; According to, by adding a surfactant when forming nanoparticles through the co-precipitation method, the first nanoparticles having excellent dispersibility and uniform particle size distribution can be prepared, and the first nanoparticles obtained using the co-precipitation method are heat-treated or The second nanoparticles prepared by hydrothermal (or solvothermal) reaction are dispersed in an aqueous or non-aqueous solvent together with various silane coupling agents, pH adjusters (acids or bases) and polymeric dispersants to obtain excellent dispersibility and uniform particle size distribution. Eggplant nanopowder can be prepared, and the nanopowder prepared according to the present invention has improved dispersibility compared to the prior art and can be sintered at a temperature lower than the generally known sintering temperature, thereby improving the properties of the sintered body. |
