Abstract (en)
[origin: FR2895412A1] Preparing a nanoparticle layer comprises: mixing a layer material with an expanding agent e.g. polyols; reacting the expanded layer with a grafting agent in the presence of water and an acid; and recovering the nanoparticle layer. Preparing a nanoparticle layer comprises: mixing a layer material with an expanding agent e.g. polyols; reacting the expanded layer with a grafting agent of formula R aXY1 4 - a in the presence of water and an acid; and recovering the nanoparticle layer. R : H or 1-40C hydrocarbon, preferably contain O or N or substituted by NH 2, COOH, epoxy or amido group; X : Ti, Zr or Si; Y1 : 1-12C alkoxy or halo; and a : 1-3. An independent claim is included for a nanoparticle foil obtained by the process, where the foil comprises percentage loss on ignition is greater than 6, preferably greater than 16.
