제목 Fabrication of Polymer Particles with Controllable and Sophisticated Structures for High Immobilization of Noble-metal Nanoparticles
초록 This research introduces the fabrication of cationic polymer particles with controllable and sophisticated structures for the high immobilization of noble-metal nanoparticles(NPs). The manipulation includes the use of a cationic extra monomer to synthesize solid spheres polystyrene(PS) with cationic character, followed by their transformation into complex-structured particles via the phase separation route in a seeded dispersion polymerization. Control of the phase separation enable us to obtain PS particles with cage-and bowl-like shapes as well as hollow structures. The large surface areas of the complex-structured particles, as theoretically calculated using simple models, and the electrostatic attraction between them and the negatively charged noble-metal NPs, as experimentally observed, enable the high immobilization of noble-metal NPs onto their surfaces.
