Title: COLOURED ORGANIC/INORGANIC HYBRID MATERIALS AND METHOD FOR PREPARING SAME
Abstract:
A method for preparing an organic/inorganic hybrid composition comprising mineral nanoparticles functionalised by at least one molecule chosen from the coloured charged organic molecules, this method comprising providing a solution (a) of at least one coloured charged organic molecule, providing a suspension (b) of non-swelling phyllosilicate nanoparticles, and bringing the solution (a) into contact with the suspension (b), the non-swelling phyllosilicate nanoparticles having a thickness of 1 nm to 100 nm, and a largest dimension of 10 nm to 10 μm. A composition of organic/inorganic hybrid coloured nanoparticles obtained by this method.
