Abstract

Soap-free emulsion polymerization was extended to preparation of monodisperse poly(methyl methacrylate) (PMMA) particles incorporating rhodamine 6G (R6G) fluorescent molecules. The polymerization was conducted in the presence of an anionic monomer, p-styrenesulfonate (NaSS), which improved dispersion stability of the polymer particles. NaSS concentrations was ranged up to 2 mol/m³ H₂O in the polymerization at 0.5 kmol/m³ H₂O methyl methacrylate (MMA) monomer and 5 mol/m³ H₂O potassium persulfate (KPS) initiator for R6G concentrations from 0.1 to 10 mol/m³-polymer. At R6G concentrations lower than 1.0 mol/m³-polymer, PMMA particles were highly monodisperse and incorporated most R6G molecules. The average sizes of PMMA particles were in a rage of 160-300 nm, and decreased with the concentration of NaSS. The high monodispersity of the particles enabled the fabrication of colloidal crystals of the particles with a vertical deposition method.
