Abstract

The physical properties of mercaptoundecanoic-acid layer formed on gold surfaces, which may affect the distribution of either gold particles adsorbed to the zirconium dioxide surface or vice versa, were investigated. To conduct this investigation, the surface forces were measured between the surfaces with respect to the salt concentration and pH value using atomic force microscope (AFM). The forces were quantitatively converted by the Derjaguin-Landau-Verwey-Overbeek (DLVO) theory to the surface potential and charge density of surfaces. The converted-value dependence on the salt concentration and pH was described with the law of mass action, and the dependence was consistent with the theoretical prediction. It was found that the mercaptoundecanoic-acid layer had higher values for the surface charge densities and potentials than the $ZrO_2$ surfaces, which may be attributed to the ionized-functional-groups of the mercaptoundecanoic-acid layer.

이산화지르코늄 표면에 흡착되는 금 입자의 분포 또는 그 반대 경우의 분포에 영향을 끼칠 수도 있는 정전기적 상호작용과 금 입자를 코팅한 mercaptoundecanoic acid층의 표면물성을 규명하였다. 이를 위하여, 원자힘현미경(AFM)으로 mercaptoundecanoic acid층 표면과 이산화지르코늄표면 사이의 표면힘을 염 농도와 pH 값에 따라 측정하였다. 측정된 힘은 Derjaguin-Landau-Verwey-overbeek (DLVO) 이론에 의해 표면의 정량적인 전하밀도와 포텐셜 값들로 전환되었다. 이 값들이 염 농도와 pH에 따라 달라지는 특성을 질량보존의 법칙으로 기술하였으며, 산출된 표면 특성의 염 농도 의존성은 이론적으로 예측했던 결과와 일치하는 것으로 확인되었다. Mercaptoundecanoic acid층의 표면이 이산화지르코늄 표면보다 높은 전하밀도와 포텐셜을 갖는 것이 발견되었는데, 이는 mercaptoundecanoic acid층의 이온화 기능기에 기인한 것으로 생각된다.
