摘要:

首先以全氟癸基三乙氧基硅烷(FAS)修饰聚苯胺(PANI)得到改性材料F-PANI，进而与有机硅树脂(SR)复合得到兼具光热与超疏水性能的功能性涂层(F-PANI涂层)。该涂层的接触角为150.8°，滚动角为3°。具有较好的力学性能、自清洁性能和防腐性能。在20℃，1 Sun条件下，F-PANI涂层表面可以在5 min内达到83.5℃。在低温条件下，涂层同样表现出优异的光热性能。在-25℃，1 Sun条件下，涂层表面的水滴在830 s时完全冻结。与SR涂层相比，结冰速度明显延迟。在-15℃，1 Sun条件下，F-PANI涂层具有一定的除霜和除冰能力。

Abstract：

The F-PANI material was synthesized by modifying polyaniline (PANI) with perfluorodecyl triethoxysilane (FAS), which was subsequently blended with silicone resin (SR) to fabricate a functional F-PANI coating that exhibits both photo-thermal and superhydrophobic properties. The coating displays a contact angle of 150.8^o and a rolling angle of 3^o, along with superior mechanical strength, self-cleaning ability, and anti-corrosion performance. Upon exposure to 1 Sun irradiation at 20^oC, the F-PANI coating can attain a surface temperature of 83.5^oC within five minutes. Additionally, the coating demonstrates excellent photo-thermal features even at low temperatures. By 1 Sun irradiation at -25^oC, water droplets on the F-PANI coating were observed to be completely freezed after 830 s, showing a significantly slower freezing rate than the SR coating. Furthermore, the F-PANI coating exhibits defrosting and de-icing capability by 1 Sun irradiation at -15^oC.

Key words： polyaniline-modified superhydrophobic anti-icing coating photothermal de-icing
