  ABSTRACT: Self-bursting microcapsules, which retain their shape when suspended in water but burst quickly after the water evaporates, were proposed in a previous report. In this report, the effect of core materials on the bursting mechanism was studied. Five kinds of solvents were used as core materials, microencapsulated with polyurethane via an interfacial polymerization method. It was found that the self-bursting ratio was proportional to the measured dielectric constant of the core material. Thus, the solvents with a higher dielectric constant had an effect on the wall material to a greater extent. Furthermore, the self-bursting ratio was able to be predicted using the “organic conceptual diagram.”
