The superhydrophobic flower-like OTS-SiO₂ particles with tunable size were synthesized for application in anti-icing technology, in which the nanosilica fibers were grown on surface of SiO₂ sphere. Furthermore, the anti-icing process of flower-like OTS-SiO₂ particles was investigated by a high speed video and thermal infrared imaging equipment. It was found that the flower-like OTS-SiO₂ particles with a diameter of 300.0 nm showed best anti-icing ability, in which the frozen time of water droplets could be prolonged to 564.0 s at −25.0℃. The good anti-icing ability was attributed to micro-nano hierarchical structure and surface modification of flower-like OTS-SiO₂ particles. The work has an important guiding implication for the subsequent design and preparation of superhydrophobic particles for application in anti-icing technology.

合成了尺寸可调的超疏水花状OTS-SiO ₂颗粒，用于防冰技术，在SiO ₂球表面生长了纳米二氧化硅纤维。此外，通过高速视频和热红外成像设备研究了花状OTS-SiO ₂颗粒的防冰过程。结果表明，直径为300.0 nm的花状OTS-SiO ₂颗粒具有最佳的防冰能力，在-25.0℃下，水滴的冻结时间可延长至564.0 s。良好的防冰能力归因于微纳米分层结构和花状OTS-SiO _2的表面改性粒子。这项工作对后续设计和制备用于防冰技术的超疏水颗粒具有重要的指导意义。
