Originální abstrakt

Novel 2-ethylhexyl acrylate (2-EHA)/cellulose acetate propionate (CAP) microcapsules with mononuclear core-shell morphology are potentially an interesting model system for polymerization inside microcapsules. Microencapsulation was performed by solvent evaporation technique from dichloromethane solution dispersed in poly(vinyl alcohol) solution. Microcapsule morphology, which evolved from partially raspberry-like to a bowl like due to premature shell formation and subsequent solvent evaporation, was captured by microscopy imaging techniques. Thus it has been concluded that kinetics of CAP shell formation play a crucial role in preparation of 2 EHA/CAP microcapsules. Moreover, microcapsules were ruptured in compression under microscope in order to evaluate fracture type. Ductile fracture of microcapsule shell was observed. Shell thickness of 0.3 μm was estimated by scanning electron microscopy. Even though bowl-like morphology of microcapsules was not favorable for polymerization inside microcapsules, some microcapsules gained irregular crumpled shape which facilitated formation of microporous hollow particles after drying the microcapsule suspension. These microporous particles may promise further research potential for development of particles with controlled release profile.
