Abstract
Poly(alkyl methacrylate)/poly(thiophene) (PAMA/PTh) core/shell nanoparticles were synthesized using a one-pot dual initiation system. A ferric chloride/hydrogen peroxide mixture and sodium vinyl sulfonate were used as an initiator couple and a reactive surfactant, respectively. In the dual initiation, process variables such as the concentration of reactive surfactant, monomer ratio, and monomer type were adjusted to control the particle size of PAMA/PTh core/shell nanoparticles from 192 to 1,172 nm. The inner structure of the core/shell nanoparticles was confirmed in their morphological transition from spherical particles to a crumpled sheath using a solvent extraction method and field-emission scanning electron microscopy. From the spectroscopic data, it was found that the UV-adsorption and fluorescent emission intensity of PAMA/PTh latexes increased with a decrease in the average particle size. The quantum efficiency of all the samples was approximately 12 % and was unaffected by the particle size.
