  • Anisotropic self-assembly of nanoparticles in composites
    Patent number: 9133314
    Abstract: An anisotropic self assembled structure comprises isotropic grafted nanoparticles in a polymeric matrix, the self-assembled structure comprising (a) a one-dimensional string of the grafted nanoparticles within the matrix, the string having a width of one nanoparticle and a length of 1-10 nanoparticles, (b) a substantially two-dimensional sheet of the grafted nanoparticles within the matrix, the sheet having a length and a breadth of at least one micron respectively, wherein the sheet is about 2-5 nanoparticles in thickness, or (c) a plurality of three dimensionally interconnected structures where the width of each of the structures is 1-10 nanoparticles; wherein each grafted nanoparticle comprises a substantially spherical inorganic core nanoparticle and a polymeric brush structure grafted thereto.
    Type: Grant
