Polymeric nanocapsules via interfacial cationic photopolymerization in miniemulsion

Nanocapsules are synthesized via UV-activated cationic polymerization of triethylene glycol divinyl ether. Such reaction is confined at the interface between the aqueous continuous phase and the oily dispersed phase of a miniemulsion. Nanocapsule size, stability against aggregation, morphology, thermal transitions and surface zeta potential are analyzed according to formulation design and processing conditions.274
