Preparation of photothermal-electrothermal synergistic superhydrophobic anti-icing coatings by resin modulation strategy

摘要

Ice accumulation is a common phenomenon in nature, but this phenomenon may seriously interfere with people's daily life and production activities, and even pose a threat to life safety. In particular, ships, offshore platforms, offshore wind power and other equipment that sail and work in cold weather or polar environment have a more urgent ne ed for surface anti -icing treatment.The research and application of superhydrophobic coatings in the field of anti-icing and de-icing has important scientific significance and application value for the development of more advanced anti -icing and de -icing t echnologies. However, superhydro -phobic coatings still face several unresolved problems in large -scale application and development, which limit their potential for widespread application. The combination of active de -icing and passive anti-icing strategies can significantly improve the anti -icing performance of materials. Based on this, various photothermal and electrothermal superhydrophobic coating s with excellent mechanical durability w ere designed and prepared. The mechanical durability, functional char acteristics, and anti -icing performance in low -temperature environments of the coatings are systematically studied.In addition, u nder the synergistic effect of photothermal-electrothermal, the coating exhibits longer delayed icing performance and rapid dei cing and defrosting capabilities. Therefore, the multifunctional integrated superhydrophobic coating can provide a new way for practical anti-icing/de-icing applications.
