Different Diameters

Monodisperse polystyrene nanospheres with different diameters and functional groups were synthesized by soap-free emulsion polymerization. Capillary electrophoresis (CE) was applied to the separation and detection of the nanospheres. Baseline separation was achieved for carboxylic and sulfonic functionalized colloids due to their difference in diameter and surface charge. The electrophoretic mobility of the sulfonic functionalized colloids decreased with increasing of particle size, and three sulfonic functionalized nanosphere samples with diameters of 190, 250 and 330 nm were separated successfully by CE.

Soap Free Emulsion Polymerization

In this paper raspberry-like composite particles were prepared via cationic soap-free emulsion polymerization with silica sol as stabilizer and 2-(methacryloyl) ethyltrimethylammonium chloride (MTC) as cationic auxiliary monomer. According to the TGA and TEM results we could find that the electrostatic attraction supplied by MTC played a vital role in the adsorption of silica particles as well as the generation of raspberry-like morphology. The silica content and appearance of composite particles were found to be improved with the increasing amount of silica sol and MTC while varied little with changes of AIBA amount.
