BACKGROUND

In the field of topical protection, an increasing interest was devoted during these past ten years to polymer/nanocomposites to improve flexibility, processability and stability of the material in which they are integrated. Yet the main difficulty still encountered during the achievement of these materials is the stability and the nature of the nanoparticles dispersion in the surrounding substance.

To facilitate the integration and to obtain an homogeneous dispersion, a new concept has been developed: the covalent grafting of nanoparticles on new amphiphilicand thickening HASE* polymers that enhance the colloidal stability in the matrices.
