Abstract:
1. An anisotropic self-assembled structure comprising: a plurality of substantially isotropic grafted nanoparticles in a polymeric matrix, the anisotropic self-assembled structure comprising (a) a one-dimensional string of the grafted nanoparticles within the polymeric matrix, the string having a width of one nanoparticle and a length of 2-10 nanoparticles, (b) a substantially two-dimensional sheet of the grafted nanoparticles within the polymeric 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 three dimensionally interconnected structures is 1-10 nanoparticles; wherein each grafted nanoparticle comprises a substantially spherical inorganic core nanoparticle and an organic brush structure grafted thereto, the organic brush structure and the polymeric matrix being molecules not covalently attached to one another, the organic brush structure and the polymeric matrix independently comprising a polymer, the polymer having the same chemical structure in the polymeric matrix as in the organic brush structure but with a different length, and wherein
