摘      要：Using lipophilic TiO2 and Fe3O4 as display particles, SDS, span80 as emulsifier and transformer oil as dispersion medium, lecithin as dispersant, homodispersed suspension was prepared. Magnetic microcapsules containing the suspension as the core material and gelatin-Arabic gum as the wall were prepared by the complex coacervation. The experiment shows that lecithin promotes the muti-phase core material stable and easy emulsification, adding acid rate, stirring speed and the mass of SDS and lecithin influence the size and the wall of the microcapsule, and different mass ratio of TiO2 and Fe3O4 has impact on the display effect.
