Ice formation on various surfaces causes catastrophic consequences or enormous economic losses. Superhydrophobic surfaces with extreme water repellency were applied for removing ice efficiently; however, their practical applications are hindered by the fabrication of the complicated micro/nanostructures of the surfaces. In this work, we proposed using hydrophilic nylon-6 nanofiber membrane coating for enhancing deicing. The nylon-6 nanofiber membrane can be easily made by electrospinning. Given the abundant kink sites provided by a large number of ice nucleation sites on the membrane, the formed ice layer could be removed quickly in the deicing process on the membrane-coated surfaces. The total time required for the ice to completely dissipated has decreased by 80% compared with a noncoated surface. The substantially enhanced deicing ability of the nylon-6 nanofiber membrane indicates its potential for practical applications.

亲水尼龙6纳米纤维膜表面的结霜和除霜
在各种表面上结冰会导致灾难性后果或巨大的经济损失。使用具有极强疏水性的超疏水表面来有效去除冰;然而,它们的实际应用受到表面复杂的微/纳米结构的制造的阻碍。在这项工作中,我们建议使用亲水性尼龙6纳米纤维膜涂层来增强除冰效果。尼龙6纳米纤维膜可通过静电纺丝轻松制造。鉴于膜上有大量冰成核位点提供了丰富的扭结位点,所形成的冰层可以在除冰过程中在膜被覆表面上快速去除。与无涂层的表面相比,冰完全消散所需的总时间减少了80%。
