Outline of Final Research Achievements

Photo-induced controlled radical polymerization has attracted recent attention for on-demand on/off control of polymerization. Organo-catalyzed iodine-transfer controlled radical polymerization is a promising approach to obtain colorless polymers with low polydispersity. The polymeric dormant containing stable C-I endgroup was prepared and utilized for chain extension/crosslinking reaction under UV irradiation. Polymerization-induced microphase-separation from miscible mixture of polymeric dormant and mono- and bi-functional acrylate monomers yielded bicontinuous morphology. Cross-sectional AFM and TEM tomography revealed evolution of unique gradient nanostructure in thickness via controlled photo-curing. The obtained nanostructured coatings are promising materials for optical coatings or porous separators.
