Abstract

Natural imogolite and its adsorption structure were studied on a Au (111) substrate by tapping- and non contact (NC)-mode atomic force microscopy (AFM). When the length of the imogolite tubes was over 2–3 micrometers, a tangled structure was observed. In contrast, when the length was shortened to 1 μm, a layered structure consisting of well-ordered imogolite tubes was formed. When the length was shortened further, imogolite tubes dispersed on the substrate. These results indicate that the adsorption structure is influenced by the interaction between imogolite tubes depending on their length, suggesting the controllability of the structures of this material. The structure of a single imogolite tube itself is also discussed.
