摘要
The synthesis of a cagelike polymer microspheres with a hollow core/porous shell structure by latex self-assembly at the emulsion droplet interface, was analyzed. The first step of the synthetic procedure is to prepare a stable emulsion from surface-sulfonated polystyrene (PS) particle by self-assembly of PS particles at the water monomer droplet interface. The hydrophilicity of PS particles was adjusted by controlling the sulfonation time and the density of chemi-grafted SO3H group on the particle surfaces. The results show that PS particles sulfonated for 21 h gave the most stable emulsion system.
