Patent number: 9840631Abstract: The present invention discloses a preparation method for a fluorinated POSS/polysiloxane hybrid coating and the anti-icing application thereof The coating is prepared by mixing fluorinatedpolyhedral oligomericsilsesquioxanes (fluorinated POSS) comprising Si-H bonds and fluoro alkyl chains in the eight vertices with polysiloxane, and subsequently curing via hydrosilylation. Fluorinated POSS aggregates on the surface of the polysiloxane hybrid coating due to the low surface energy fluorinated chains, leading to the generation of micro/nano-sized wrinkles. The wrinkles, together with lubricant, contribute to the low water contact angle hysteresis (as low as 2°) and ice shear strength (as low as 20 kPa). The required materials are easy to obtain, and the preparation is simple and controllable. All the above make it promising as anti-icing coatings.Type: GrantFiled: October 28, 2014Date of Patent: December 12, 2017Assignee: Tianjin UniversityInventors: Xiaoyan Yuan, Chao Tao, Kongying Zhu, Chenghao Luo, Yunhui Zhao, Xiaohui Li, Kaiqiang Zhang
