Abstract
For the sake of the sustainable development, we prepared a blend by diallyl drisulfide and natural polymer coating-urushiol through radical chain termination reaction under UV irradiation. Based on the successful preparation of target materials which was characterized by FT-IR, the surface energy and reversible cross-linking functionalization of materials are mainly explored. The basic mechanisms active in microstructure and the associated surface energy were elucidated. Various disulfide densities brought about different microstructures on the modified urushiol. It was found that the surface energy of film had been enhanced after UV-curing and its increase was related to the phase inversion (represented by microstructure). The reversibly cross-linking test showed that the introduction of disulfide bonds assists in achieving the reversible cross-linking under extreme alkalinity. What was more, the existence of flexible segments offered the coating composition with excellent flexibility (2 mm) and rheological properties (5 mPa. S), while the hardness of coating dropped to 3H.
