摘要： Provided are a method for preparing zinc oxide (ZnO) nanoparticles and a method for preparing ZnO nanofluid using the same. The method for preparing ZnO nanoparticles includes: a) heating deionized water; b) dissolving zinc (Zn) salt in the deionized water to prepare a precursor solution; c) adding solid alkali salt to the precursor solution to prepare a dispersion of ZnO nanoparticles; and d) separating the ZnO nanoparticles by solid-liquid separation and washing them with deionized water. Highly pure, crystalline ZnO nanoparticles with spherical shape and very narrow particle size distribution of 10 to 50 nm can be prepared quickly and at large scale and low cost using inexpensive materials via a stable low-temperature process, without using a dispersant. The associated low-temperature, normal-pressure process produces few harmful materials and may be easily employed for production of ZnO nanoparticles.

摘要： The present invention provides a method for preparing microtubular halloysite nanopowders by cutting halloysite nanotubes at a high pressure, microtubular halloysite nanopowders prepared by the method, and a cosmetic composition comprising the microtubular halloysite nanopowders. According to the method of the present invention, it is possible to prepare the halloysite nanopowders with a tubular shape using natural halloysite and effectively select a halloysite nanopowder having a desired shape. The microtubular halloysite nanopowders can be used in many industrial fields and used as a container or a carrier for nanoparticles or organic materials such as drugs, air fresheners, cosmetics, agricultural chemical materials, etc.
