Outline of Final Research Achievements

In this study, we prepared colorless PDA layer containing atom transfer radical polymerization (ATRP) initiator prepared by the reaction of DA with 2-bromoisobutyryl bromide (BiBB). The synthesized colorless PDA/BiBB2 layer ([BiBB]/ [DA] = 2) was successfully covered onto various types substrates, e.g., glass plates, flexible polypropylene films, filter papers, silica particles, and polymer particles. Then, the surface-initiated ATRP was conducted to create bio- and smart-interfaces (Hierarchically structured coating). Furthermore, preparation of polymer brush based materials, colored particles, and raspberry-like particles based on colorless PDA coating were also investigated.
