FILLED NANOPARTICLES

摘要

A filled nanoparticle includes a nanosized polymer shell encapsulating a reactive chemical. In another aspect, a filled nanoparticle includes a nanosized polymer shell encapsulating a core which includes a reactive functional group attached to a polymer. A miniemulsion polymerization process of producing filled nanoparticles includes: providing a mixture comprising monomer, initiator or catalyst to aid polymerization, reactive chemical, surfactant and water; shearing the mixture to form a miniemulsion of nanosized particles dispersed in water, the nanosized particles comprising the monomer combined with the reactive chemical; and then heating the miniemulsion to polymerize the monomer and produce filled nanoparticles comprising a nanosized polymer shell encapsulating the reactive chemical.
