Encapsulation of two-phase core materials into electronic ink nanocapsules by miniemulsion polymerization

Miniemulsion polymerization was used to produce encapsulation of two-phase electronic ink nanocapsules-carbon black/TiO ₂ nanoparticles as dispersant phase and the mixture of tetrachloroethylene (TEC) and SPAN-80 as dispersant agent. In this experiment, styrene (SM)-methyl methacrylate (MMA) was used as reaction monomers, hexadecane (HD) as hydrophobe, azobisisobutyronitrile (AIBN) as initiator, polyvinyl alcohol (PVA) as surfactant and ethanol as solvent. In this article, we do a lot of research on nanocapsules that encapsulate different chemicals such as organic colloidal of TiO ₂, carbon black nanoparticles, TiO ₂ nanoparticles and the pure polymer nanoparticles and discuss the effects of PVA content, ethanol and different surface modification on nano-encapsulated particles on particle size and particle size distribution of carbon black/TiO ₂ nanoparticles.
