Definitions
- the present invention relates to a method for producing nanoparticles, which is prepared by pulverizing powder particles to nano size using carbon nanotubes.
- Nanoparticles have a much smaller particle size compared to the wavelength of ultraviolet or visible light, form a larger grain boundary relative to the mass of the particle, and a larger number of atoms or molecules at the interface than the bulk material. Positioning allows not only to form micro / nano hybrid structures, but also to change physical, chemical and optical properties depending on the size and morphology of the particles.
- Nanoparticles include organic materials (for example, polymers), inorganic materials (for example, metals), ceramics, and the like.
- the preparation method of the nanoparticles includes a polymer polymerization method and a self-assembly method such as suspension polymerization, emulsion polymerization, and dispersion polymerization in the case of organic materials.
- the inorganic substance includes a thermal decomposition method, a vacuum deposition method, a colloid method, an electrolytic and electroless reduction method of an organic metal precursor.
- An example of using the solution method is a method of preparing silver nanoparticles (domestic application 10-2006-0101844), which is a method of using a reducing agent after dissolving a compound containing silver in a polar solvent.
- Silver nanoparticles prepared using this method have a uniform amount, but have a limited amount of production because a complicated manufacturing process is required.
- a method for preparing nanoparticles is a vapor condensation method (domestic application 10-2007-7004335), which is a method of rapidly condensing a metal by evaporating it at high temperature and high vacuum. Condensation occurs quickly when the evaporated gaseous metal atoms are rapidly cooled. As a result, a large amount of nuclei are generated and crystals and particles become smaller. Using this principle, nanoparticles are produced. This method also requires high heat, high vacuum, etc., and all have to be evaporated in order to produce nanoparticles.
- a bottom-up method which is a method of manufacturing nanostructures in which clusters are accumulated from atoms or ions. Therefore, the disadvantage of this method is that it requires a process to generate initial atoms or ions and control the crystal to nano size. In the case of the solution method, the density must be controlled and in the case of the evaporation method gas atoms must be produced. Therefore, the productivity is limited.
- An object of the present invention is to provide a method for producing nanoparticles using carbon nanotubes.
- Carbon nanotubes are structurally stable and have excellent mechanical properties. Therefore, when the carbon nanotubes collide with the material, the material can be crushed. In addition, the nano-size allows the material to be crushed to nano-sized.
- the present invention provides a method of preparing bulk materials into nanoparticles using a novel method different from the conventional method.
- Another object of the present invention is to provide a nanoparticle produced by the above method.

- the present invention in one embodiment, the present invention, the present invention
- It provides a method for producing a nanoparticle comprising a.
- the present invention provides a nanoparticle composite comprising powder particles and carbon nanotubes pulverized into carbon nanotubes by a ball mill.
- Carbon nanotubes used to prepare nanoparticles in the present invention include single-walled carbon nanotubes (SWNT), double-walled carbon nanotubes (DWNT), thin multi-walled carbon nanotubes ( One or a mixture of two or more selected from the group consisting of thin multi-walled carbon nanotubes and multi-walled carbon nanotubes (MWNTs) may be used.
- Carbon nanotubes consist of carbons with sp 2 hybrid bonds and are structurally stable. As a result, it has more than 100 times stronger mechanical properties than steel.
- the carbon nanotubes In order to accomplish this task, the carbon nanotubes must be physically impacted to pulverize the powder particles. To do so, a ball mill process is required to physically impact the carbon nanotubes. In addition, in the general ball mill, the size of the powder particles is reduced in the process of pulverizing the powder particles, and at a certain critical size, the particles are welded to each other again. Carbon nanotubes are attached to the surface of the powder particles to prevent this phenomenon.
- the manufacturing method of the present invention is divided into a powder particle grinding process by a ball mill and a nano particle generation process by carbon nanotubes.
- a step of heat treatment which is a method for improving the crystallinity of the carbon nanotubes before the ball mill.
- the nanoparticles include metal, polymer, or ceramic nanoparticles, but the object may be expanded in various ways according to the purpose.
- the metal is not limited thereto, but gold, silver, copper, aluminum, manganese, iron, tin, zinc, titanium, and the like can be used.
- the polymer is not limited to this, but is not limited to polyphosphazene, polylactide, polylactide-co-glycolide-polycaprolactone, polyanhydride, polymalysac, polyalkylcyanoacrylate, poly Hydrooxybutylate, polycarbonate, poriosoester, polyethylene glycol, poly-L-lysine, polyglycolide, polymethylmethacrylate, polyvinylpyrrolidone and the like can be used.
- the ceramic is not limited to this, but Cubic boron as a nitride, such as tungsten carbide (WC), titanium carbide (TiC), silicon carbide (SiC), etc., as a carbide, such as alumina and zirconia Nitride (CBN), titanium nitride (TiN), silicon nitride (Si 3 N 4 ), or the like may be used.

- the ball milling process shown in FIG. When the micronization process of the powder particles by the ball proceeds, in general, the particles do not become smaller any longer, and welding of the particles occurs. Therefore, there is a limit to reducing the size of the particles due to the grinding method by the ball mill.
- the use of carbon nanotubes not only suppresses the welding process between the particles, but also carbon nanotubes crush the particles.
