摘要
The effect of chemical heterogeneity on the adsorption of Methyl Orange (MO) in aqueous solutions was investigated by atomic force microscopy (AFM). On hydrophilic mica, a small number of disordered islands of Methyl Orange were formed. However, after deposition of self-assembled monolayers (SAMs) of octadecyltrichlorosilane (OTS) on mica, MO mole-cules adsorbed extensively and selectively on the hydrophobic OTS SAMs. Most importantly, the MO molecules on hydropho-bic domains were highly ordered and almost perpendicular to the OTS surface.
