Abstract
A method for preparing an organic/inorganic hybrid composition including mineral nanoparticles functionalized by at least one molecule chosen from colored charged organic molecules, this method including providing a solution (a) of at least one colored charged organic molecule, providing a suspension (b) of non-swelling phyllosilicate nanoparticles, contacting the solution (a) and the suspension (b), the non-swelling phyllosilicate nanoparticles having a thickness of 1 nm to 100 nm, and a larger dimension of 10 nm to 10 μm. A composition of organic/inorganic hybrid colored nanoparticles obtained by this method is also disclosed.
