Recently, the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences (abbreviated as Lanhua Institute) has used a simple, economical and practical method of preparing organic coating materials to build micro/nano structures on the surfaces of metal materials such as aluminum, copper and steel. The hydrophobic surface functional coating material solves the key technical problem that the construction method of the superhydrophobic coating material is complicated and practical and difficult in engineering application. The project team used PTFE and polyphenylene sulfide composite polymers to form 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 superhydrophobic properties (contact angle of about 165°; rolling angle of about 4°), high bonding strength with the substrate, excellent acid and alkali resistance, good resistance to high and low temperatures, and long-term stability. The engineering application of super-hydrophobic organic coating materials laid the foundation for science and technology.
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 and multiple applications have been filed and obtained in the above fields.
