内容記述 | We have developed a chemical modification process for the surface of nanodiamond particles using supercritical CO2. Using surface chemical modifiers (stearic acid and p-aminobenzoic acid), the relationship between the amount of modification on the nanodiamond surface and operating conditions and the effect of the phase state of the surface modifier were examined. In addition, the chemical bonding on the surface of the modified nanoparticles was clarified by by infrared absorption spectra, TG, and TEM, etc. Also the dispersibility of the modified nanodiamond in organic solvent was clarified by the average particle size distribution. Furthermore, since the concentration of the surface modifier greatly affects the chemical reaction mechanism, we developed a experimental apparatus for the solubility of the surface modifier in supercritical CO2 and obserbed the behavior of the solubility. We also developed thermodynamic analysis and calculation methods by various state equations. | |||||
