Electrostatic Properties of N-Acetyl-Cysteine-Coated Gold Surfaces Interacting with TiO2 Surfaces |
| 초록 |
It is found that that the coating N-acetyl cysteine (NAC) on gold surfaces may be used to design the distribution of either gold particle adsorbed to the TiO2 surface or vice versa by adjusting the electrostatic interactions. Theinteractions between the NAC -coated-gold surface and the TiO2 surface were investigatedwith respect tothe salt concentration and pH value using the AFM. The Derjaguin-Landau-Verwey-Overbeek (DLVO) theory was applied to the interactionsso thatthe surface potential and charge density of the surfacescould bequantitatively acquired for each salt concentration and each pH value. The surface potential and charge density dependence on the salt concentration was described with the law of mass action, and the pH dependence was with the ionizable groups on the surface. |
