Abstract
This paper describes technique to control nanoparticle structure and array. As the first part, a modified inorganic template was introduced to prepare skeletal silica nanoparticles with unique structure composed of silica nanoframe and wide square windows. Affinities between modifying organic acid, silica source, and reaction medium are important factors for precise control of frame structure. As the latter part, a novel nanoparticle array technique based on a micro-phase separation was proposed. By only solvent vaporization, polymeric guide for nanoparticle array forms through phase separation into polar and non-polar phases. This separation flow arrays silver nanoparticle as a three-dimensional network. These two proposed techniques can be valid to maximize nanopaprticle functionalities.
