1) Controlled polymerization and well-defined polymers.
We study controlled radical polymerization and focus on ATRP of novel monomers for functional polymers. By applying controlled polymerization we have developed some new approaches to prepare well-defined polymers such star polymers hyperbranched polymers novel molecular brushes and functional block copolymers.
2) Self-assembly of the well-defined polymers and nanoparticles.
Our interest is to apply functional block copolymers to prepare well-defined nanoaggregates and nanoparticles. We have developed a novel approach to prepare organic-inorganic hybrid nanoparticles. It is based upon gelation process in preformed self-assembly of a reactive block copolymer in a selective solvent. Furthermore the relation of polymer architecture and its aggregate morphology is also our interest.
