Abstract (en)

[origin: WO02072674A1] The method for the production of a nanocomposite dispersion comprising a solvent, a resin and a nanoparticlulate mineral charge consists of the following steps: a) the mineral charge is dispersed in the solvent, generally at a shear speed of gamma < gamma MAX, in order to obtain a nanoparticulate dispersion of exfoliated lamellae, said mineral charge having been previously selected according to the solvent, in order to obtain a fluid nanoparticulate dispersion comprising exfoliated lamellae having a high average form factor, b) said resin is then incorporated into the nanoparticulate dispersion in order to form the nanocomposite dispersion. The nanoparticulate dispersion is then applied to a support, generally by means of coating.
