제목 Synthesis and characterization of Chemical Containing Polymer Nanoparticles
초록 In this paper, we successfully synthesized polymer nanoparticle and silica nanoparticle. Copolymer nanoparticles having amphipathic properties can be prepared by adjusting the ratio of solvent. The particle size can be controlled from 100 nm to 900 nm according to the solvent ratio. In case of polyelectrolyte micelle, the surface charge was confirmed by zeta potential analysis. The negative and the positive charge were observed, respectively, which was the basis for binding with other ligands. Hollow silica nanoparticles (HSN) mainly have focused on micelle states in order to get hollow structure and appropriate sizes. we tried to synthesize homogeneous HSN by using sol-gel reaction with cetyl trimethyl ammonium bromide (CTAB) micelle containing tetraethoxysilane (TEOS). The size of micelle can be controlled reaction condition such as temperature, reaction time and ammonia solution concentration.
