Article Synopsis
- The study successfully synthesized superparamagnetic latex particles that respond quickly to magnetic fields, using commercial iron oxide nanoparticles.
- The assembly involved an emulsification/solvent evaporation method combined with a specific cross-linking agent (divinylbenzene) to maintain the integrity of iron oxide clusters during the process.
- The resulting particles exhibited tailored surface properties and are promising for biological applications due to their responsiveness to temperature and pH changes.
High solids content film-forming poly[styrene-co-(n-butyl acrylate)] [poly(Sty-co-BuA)] latexes armored with Laponite clay platelets have been synthesized by soap-free emulsion copolymerization of styrene and n-butyl acrylate. The polymerizations were performed in batch in the presence of Laponite and a methyl ether acrylate-terminated poly(ethylene glycol) macromonomer in order to promote polymer/clay association. The overall polymerization kinetics showed a pronounced effect of clay on nucleation and stabilization of the latex particles.
