| dc.description.abstract | In this work, various sizes of monodisperse polystyrene particles (10 wt%,80~600nm) were prepared in the presence of sodium, p-styrenesulfonate (NaSS, 2.0~0wt% based on styrene) and styrene. Then, the dye-containing polymer beads were prepared by introducing the different concentration of dye and solvent or styrene and divinylbenzen in polystyrene particle latex, respectively. The characteristics of self-assemble PS microspheres were observed by SEM, DLS, and ultraviolet-visible spectrophotometer. The results showed that with increasing the concentration of NaSS, the size of polystyrene was
decreased from 600nm to 80 nm.
Highly monodisperse dye-containing polymer beads were prepared by introducing dye and solvent when the dye concentration was lower than 1.0wt% (based on polymer) and by introducing dye and monomers when the dye concentration was lower than 0.05wt% (based on polymer), respectively. But the particle diameter with crosslinked structure was increased to 1.3 times when dye-containing polymer beads prepared by
introducing dye and monomers.
The wavelength of peaks in the reflective spectrum on the set of (111) planes in the face-centered cubic package of self-assembled dye-containing polymer beads with 188, 210, and 280 nm diameters were 450.7, 508.0, and 683.0 nm, respectively. In addition, the more vivid blue, green and red colors were observed when the more dye in those dye-containing polymer beads, respectively. These phenomena were also observed by SEM and photo image of above dye-containing polymer
beads. | en_US |
