Outline of Final Research Achievements

We have demonstrated the hybridization of urushiol with other materials. The hybridization with initiator-containing silane coupling agent imparts the surface-initiated atom-transfer-radical polymerization (SI-ATRP) of polymer brushes from urushiol thin films. Since urushiol thin film can form on variety of substrates, the concept shown here could be a universal approach for surface modifications of substrates. With the hybridization with hydrogenated urushiol, the regular side chain structure of hydrogenated urushiol increase the mechanical strength of the thin film at high contents of the material. It may arise from the highly packed structure of the side chain. Our results will help to develop biomimetic catechol-based coatings.
