Recently, a research team from the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences (LICP), led by researchers Zhang Zhaozhu and Liu Weimin, has developed an innovative and cost-effective method for preparing composite organic coating materials. This approach enables the creation of super-hydrophobic surfaces on various metal substrates, including aluminum, copper, and steel. The newly developed coating features a micro/nanostructured surface with low surface energy hydrophobic groups, effectively solving the long-standing challenge of complex and impractical methods in engineering applications of super-hydrophobic coatings.
The team utilized a one-step film-forming technique involving a combination of PTFE and polyphenylene sulfide polymers to fabricate a porous, hierarchical structure that exhibits exceptional super-hydrophobic properties. The resulting coating not only demonstrates strong adhesion to the substrate but also shows remarkable resistance to acids, alkalis, extreme temperatures, and long-term stability. These characteristics make it highly suitable for practical engineering applications. The findings were published in *Advanced Materials* (2008, 20, 970–974).
The Lanzhou Institute of Chemical Physics has been conducting research on low surface energy organic coatings since the 1990s. In recent years, significant progress has been made in the development of micro/nanostructured surfaces with enhanced hydrophobic properties. Their work has been widely recognized, with publications in prestigious journals such as *JACS*, *Applied Physics Letters*, and *ChemPhysChem*. Additionally, multiple Chinese invention patents have been filed and granted in this field.
This research has been supported by key national funding programs, including the National Natural Science Foundation of China and the 973 Program under the Ministry of Science and Technology. These efforts highlight the growing importance of super-hydrophobic materials in advanced material science and their potential for broad industrial applications.
