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. Unique gradient nanostructure in thickness evolved via controlled photo-curing was investigated by cross-sectional AFM and TEM tomography. Metal (oxide) nanoparticles were selectively integrated into such well-defined nanostructures and their optical- and electronic properties will be discussed.
