Abstract:

swelling; core-shell microspheres; Janus; solubility parameter; polar fraction Abstract. Janus particles have particular properties and potential application for their asymmetry dual-faced structure. In this report, we study the effect of the solubility parameter and the polar fraction of solvent on the swelling assisted with protrusion of polystyrene @ titanium dioxide (PS@TiO2) core-shell microspheres. The resultant titanium dioxide/polystyrene (TiO2/PS) Janus particles were characterized by scanning electron microscope. Results indicated that solvent with the solubility parameter of about 9.3 (cal/cm3)1/2 and with low polarity such as dimethylbenzene, carbon disulfide and methyl methacrylate exhibited the preferable swelling efficiency.
