In recent years, a research team from the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences (LICP), led by Zhang Zhaozhu and Liu Weimin, has developed an innovative and cost-effective method for creating super-hydrophobic composite coatings on various metal substrates such as aluminum, copper, and steel. This breakthrough addresses a major challenge in the field: the complexity and practical limitations of traditional methods for fabricating super-hydrophobic coatings for real-world applications.
The team employed a one-step film-forming technique using a combination of polytetrafluoroethylene (PTFE) and polyphenylene sulfide (PPS) to create a coating with a unique micro/nano porous structure. This design not only provides low surface energy, enhancing hydrophobic properties, but also ensures strong adhesion to the metal substrate. The resulting material exhibits remarkable super-hydrophobic performance, along with excellent resistance to acids, bases, extreme temperatures, and long-term stability. These features make it highly suitable for industrial and engineering applications.
The study was published in the prestigious journal *Advanced Materials* (2008, 20, 970–974). In addition to this achievement, the Lanzhou Institute has made significant progress in the development of surface micro/nanostructures and hydrophobic technologies for engineering materials. The institute has filed and obtained multiple Chinese invention patents in this area, demonstrating its leadership in the field. The research was supported by the National Natural Science Foundation of China and the "973" Program under the Ministry of Science and Technology, highlighting its importance in both academic and industrial contexts.
