Fabrication of Ruthenium Oxide Nanoparticles by A Solution Method |
| 초록 |
Recently, the ink-jet patterning of LCR components has been considered. To be compatible for ink-jet printing of R component, it is necessary to fabricate the nanoparticle with high resistance. A RuO2 has ohmic conductivity with high chemical and thermal stability. It is known that the RuO2 chemistry compared with that of other metal oxides is more complicate. Various synthetic methods have been used to fabricate RuO2, such as solvothermal reaction, precipitation method, sol-gel method and so on. A solution synthesis such as a micelle system is promising method to prepare nanoscale particles. In the present work, a novel synthetic method using a reverse micelle system was designed for preparing of nanoscale RuO2 powders. The reverse micelle system for the reaction was formed from a surfactant (Igepal CO520) and cyclohexane. For characterization of the RuO2 powders, X-ray diffractometry, thermal gravimetry-differential thermal analysis, scanning electron and transmission electron micrographs were used. The obtained nanoscale RuO2 has 5-8 nm in particle size and spherical type in shape with well-dispersion. |
