    Abstract: The present invention relates to a method for manufacturing hybrid imogolite nanotubes, which includes the following steps: (i) dissolving an aluminium precursor in an aqueous solution; (vi) under agitation, adding at least one silicon alkoxide, in which the silicon has hydrolysable substituents and at least one non-hydrolysable substituent, to the aluminium solution obtained at the end of step (i), the molar ratio of Al/Si necessarily being from 1 to 4; (vii) under agitation, adding a base to the aluminosilicate solution obtained at the end of step (ii), until obtaining a hydrolysis ratio of 1 to 3; (viii) maintaining agitation for a duration of at least 15 hours; (ix) heating the solution obtained at the end of step (iv) to a temperature of 50° C. to 150° C. for a duration of 2 to 8 days. The present invention also relates to hybrid imogolite nanotubes that simultaneously include a hydrophilic surface and a hydrophobic surface, and have an outer diameter of 3.3 nm to 3.
