烷酸在铝的天然氧化物表面上的吸附很弱。首先用锆烷氧化物处理氧化物表面，提供了随后对烷酸的强烈吸附。界面羧酸锆盐的形成导致了这种强烈的粘附性。采用石英晶体微天平和超高真空红外光谱技术相结合的方法，确定了界面羧酸锆膜的化学计量比和结构特征。
Alkanoic acids adsorb weakly to the native oxide surface of aluminum. Treating the oxide surface first with an alkoxide of zirconium provides for strong subsequent adsorption of the alkanoic acid. The formation of an interfacial zirconium carboxylate gives rise to this strong adhesion. A combination of quartz crystal microbalance and ultrahigh-vacuum IR spectroscopic techniques were used to establish the stoichiometry and structural features of the interfacial zirconium carboxylate film.
