title: Mono-dispersed Functional Polymeric Nanocapsules with Multi-lacuna via Soapless Microemulsion Polymerization with Spindle-like alpha-Fe(2)O(3) Nanoparticles as Templates.
abstract: The mono-dispersed crosslinked polymeric multi-lacuna nanocapsules (CP(St-OA) nanocapsules) about 40 nm with carboxylic groups on their inner and outer surfaces were fabricated in the present work. The small conglomerations of the oleic acid modified spindle-like alpha-Fe(2)O(3) nanoparticles (OA-Fe(2)O(3)) were encapsulated in the facile microemulsion polymerization with styrene (St) as monomer and divinyl benzene (DVB) as crosslinker. Then the templates, small conglomerations of OA-Fe(2)O(3), were etched with HCl in tetrahydrofuran (THF). The surface carboxylic groups of the crosslinked polymeric multi-lacuna nanocapsules were validated by the Zeta potential analysis.
