The purpose of this project is preparing a novel effective and environment-friendly antibacterial coating. Firstly, based on designing polymerization process and optimizing technology conditions, the polymer Janus particles will be synthesized in large amounts. Then, the polymer composite antibacterial emulsion with Janus particles and the polymer Janus particles containing antibacterial constitutional units will be synthesized and characterized by SEM, TEM, DLS, IR, XRD and XPS. Secondly, using the polymer composite antibacterial emulsion with Janus particles and the polymer Janus particles containing antibacterial constitutional units as film forming matter, the antibacterial coating will be prepared with combining porous inorganic pigments and fillers. Its antibacterial activity and basic performance of coatings will be measured. Thirdly, the relationship between morphology, performance of polymer Janus particles and monomer structure, forming polymer chain and aggregation process of functional chains will be investigated. The relationship between antibacterial activity and topographic characteristics will be investigated. It will be useful to enlarge application of polymer Janus particles. In summary, with exploring novel technology for synthesizing polymer Janus particles in large amounts, it will enlarge application of polymer Janus particles. It also will be useful to synthesize novel smart materials.
