Surface Modification of Aluminosilicate Nanofiber “Imogolite”

Abstract
The nanostructure of natural aluminosilicate nanofiber “imogolite” under acidic conditions was directly confirmed by observation with atomic force microscope (AFM) for the first time. The outer surface of imogolite was successfully hydrophobidized by chemisorption of a phosphonic acid derivative with an alkyl chain.
