Recently, researchers from the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences (abbreviated as Lanhua Institute), led by researcher Zhang Zhaozhu and researcher Liu Weimin, used a simple, economical and practical method of preparing composite organic coating materials to surface the surface of metal materials such as aluminum, copper and steel. A super-hydrophobic surface functional coating material with a micro/nano structure was developed, which solved the key technical problem of the construction method of the super-hydrophobic coating material in engineering applications that is complicated and practically difficult. The project team used PTFE and polyphenylene sulfide composite polymers to construct a superhydrophobic coating with a low surface energy hydrophobic group and a porous network micro-nanostructure on the surface using a one-step film-forming method. The coating has excellent super-hydrophobic performance, high bonding strength with the substrate, excellent acid and alkali resistant media properties, good resistance to high and low temperature and long-term stability, and lays a scientific foundation for engineering applications of super-hydrophobic organic coating materials. technical foundation. The results of this study were published in the recently published Advanced Materials (2008, 20, 970-974).
The Lanzhou Institute of Chemical Physics began research on low surface energy organic coating materials in the 1990s. In recent years, good progress has been made in the preparation of surface micro/nanostructures and hydrophobic properties of engineering materials. The results of the research have been published in JACS. Applied Physics Letters, 2006, 89, 081911; ChemPhysChem, 2006, 7, 1674; 254, 2563 and other publications, and have filed and obtained multiple Chinese invention patents in the above fields.
This series of research work has been supported by the National Natural Science Foundation of China and the 973 Program of the Ministry of Science and Technology.
