Outline of Final Research Achievements

Polymer capsules containing small particles were prepared via a one-step suspension polymerization using the Self-assembling Phase Separated Polymer (SaPSeP) method from ethylene glycol dimethacrylate (EGDM)/liquid crystal (LC) droplets containing dissolved polystyrene (PS). We estimated the formation mechanism as following: the encapsulated small particles consisted of poly EGDM, and were formed via precipitation polymerization inside the droplets in competition with formation of the shell. Because the small particles coagulated in the capsules owing to the phase separation of the PS, a toluene/n-hexadecane solution containing an oil-soluble surfactant (polydimethylsiloxane-based macroazoinitiator) was used instead of the LC/PS mixture. Thus, “rattle-like” capsules were successfully prepared using a simple polymerization process. The small particles could move in the capsule and responsed the electric field because the particles having -9 mV of zeta potential.
