Abstract : The natural Imogolite clay ((HO)$_3$Al$_2$O$_3$SiOH) with nano-tubular structure of 2-3 nm diameter is a promising candidate for polymer reinforcement, water treatment and other applications. However, its hydrophilic external gibbsite like surface limits its use in hydrophobic environment. Among the different possible grafting functions for the outer surface, the phosphonic acid moiety is the most used. It shows strong reactivity with imogolite. If the resulting product can be dispersed in a hydrophobic environment, the impact of the reaction on the tubular structure was never demonstrated and experimental evidence of grafted dispersed imogolite tubes with a brush-like layer on their exterior is still missing
