The construction of halloysite spherical capsules (halloysite aerogels) was reported for the first time in our previous work. The excellent performance of the microcapsule in functional carrying was also found in our further research. In this work, the anti-icing surface was fabricated by using halloysite nanotubes and halloysite spherical microcapsules. The fabrication of the anti-icing coating was investigated, and the ice nucleation behavior of droplet on the coating surface was studied. The modified halloysite nanotubes (F-HNTs) and the modified halloysite microcapsules (F-HAs) were characterized by Fourier-transform infrared spectroscopy, thermal gravimetric, and pore size distribution. The results show that the introduction of F-HNTs and F-HAs have successfully formed a micro-nano structure on the coating surface with superhydrophobicity performance. The icing temperature of the coating has decreased 2.3 °C compared with bare glass, and the ice adhesion strength has decreased 82%. According to the ice dynamic mechanics, the ice nucleation rate on the coating is significantly reduced, thus the halloysite microcapsule coating has good icephobic performance.

在我们以前的工作中，首次报道了埃洛石球形胶囊（哈洛石气凝胶）的构建。在我们的进一步研究中还发现了微囊在功能性携带中的优异性能。在这项工作中，通过使用埃洛石纳米管和埃洛石球形微胶囊制备防冰表面。研究了防冰涂层的制备，研究了液滴在涂层表面的冰核行为。改性的埃洛石纳米管（F-HNTs）和改性的埃洛石微胶囊（F-HAs）通过傅里叶变换红外光谱，热重和孔径分布进行表征。结果表明，F-HNTs和F-HAs的引入已成功地在涂层表面形成了具有超疏水性能的微纳米结构。与裸玻璃相比，涂层的结冰温度降低了2.3°C，冰粘附强度降低了82％。根据冰动力力学，涂层上的冰成核速率大大降低，因此埃洛石微胶囊涂层具有良好的疏冰性能。
