Recently, a research team from the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences (LICP), led by researchers Zhang Zhaozhu and Liu Weimin, developed an innovative and cost-effective method for preparing composite organic coating materials. This approach was used to create 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 in engineering applications of achieving practical and efficient super-hydrophobic coatings.
The team utilized a one-step film-forming process combining PTFE and polyphenylene sulfide polymers to construct a porous network structure with excellent hydrophobic properties. The resulting coating exhibits remarkable super-hydrophobic performance, strong adhesion to the substrate, outstanding resistance to acidic and alkaline environments, and stability across a wide temperature range. These characteristics make it highly suitable for long-term use in real-world applications. The findings were published in *Advanced Materials* (2008, 20, 970–974).
Since the 1990s, the Lanzhou Institute has been actively researching low surface energy organic coatings. In recent years, significant progress has been made in developing surface micro/nanostructures and enhancing the hydrophobic properties of engineering materials. Their work has been featured in reputable journals such as *JACS*, *Applied Physics Letters* (2006, 89, 081911), *ChemPhysChem* (2006, 7, 1674), and others. Additionally, several Chinese invention patents have been filed and granted in this field.
This groundbreaking research has received support from the National Natural Science Foundation of China and the 973 Program under the Ministry of Science and Technology. The development of such advanced coating technologies opens new possibilities for industrial applications, offering durable, environmentally stable, and cost-effective solutions for surface protection.
