In this study, poly(1H,1H-dihydroperfluorooctyl methacrylate)-block-polyethylene oxide (poly(FOMA20k-b-EO20k)) diblock copolymers were used to form micelles, i.e. small compartments in which gold particles are generated and which allow us to prepare thin, coherent films with a well controlled particulate structure. We compatibilized gold nanoparticles, thereby rendering the nanocrystal-PEO system to interact favorably with the PEO phase. Upon annealing the sample formed a single gold nanocluster within each diblock copolymer micelle. Kinetic control over the polymer film morphology proved to be an effective means of arranging the nanoparticles in an ordered array. Furthermore, the sizes of the nanoclusters could be controlled by varying the volume fraction of each block or the ratio of LiAuCl4 to EO. |
