The invention relates to an anti-icing-deicing composite surface and a preparation method thereof, and belongs to the field of anti-icing and deicing. The surface comprises a porous material substrate, a super-hydrophobic/hydrophobic lubricating fluid top microstructure and a hydrophobic/hydrophilic lubricating fluid internal microstructure, wherein the super-hydrophobic/hydrophobic lubricating fluid top microstructure and the hydrophobic/hydrophilic lubricating fluid internal microstructure are coupled to the surface of the porous material substrate; lubricating fluid is injected into the surface of the hydrophobic/hydrophilic lubricating fluid internal microstructure; the super-hydrophobic/hydrophobic lubricating fluid top microstructure is located on the surfaces of a plurality of columnar bodies arranged on the porous material substrate in an array mode, namely, the super-hydrophobic/hydrophobic lubricating fluid top microstructure has the super-hydrophobic characteristic to water and lubricating fluid. And the hydrophobic/lubricating fluid-loving internal microstructures are also arranged in the array form, surround the root of each cylindrical object, and have the characteristics of lubricating fluid loving and hydrophobicity. The surface can have anti-icing/ice-dredging properties of super-hydrophobic and super-smooth properties at the same time, that is, the surface can have excellent anti-icing properties of a super-hydrophobic surface, and can also be ice-dredging like a super-smooth surface after the surface is iced, so that ice is easier to remove.

    本发明一种防冰‑疏冰复合表面及制备方法,属于防冰疏冰领域;该表面包括多孔材料基底及耦合于其表面的超疏水/疏润滑流体顶部微结构和疏水/亲润滑流体内部微结构,所述疏水/亲润滑流体内部微结构表面注有润滑流体;所述超疏水/疏润滑流体顶部微结构位于以阵列形式排布于多孔材料基底上的若干柱状体的表面,即对水和润滑流体均具有超疏特性;所述疏水/亲润滑流体内部微结构同样以阵列形式排布,并环绕于各柱状体的根部周围,具有亲润滑流体和疏水的特性。本发明表面能够同时兼具超疏水特性和超滑特性的防冰/疏冰性能,即能具备超疏水表面优异的防冰性能,还能够在表面结冰后,像超滑表面一样疏冰,让冰更容易去除。
