Abstract

The invention provides a preparation method of a super hydrophobic fiber material. The preparation method comprises following steps: a nano material is dispersed in a dispersing agent so as to obtain a mixed solution; adhesion of the mixed solution onto a fiber material is carried out; and the fiber material with the mixed solution is subjected to vacuum activation so as to obtain the super hydrophobic fiber material, wherein the surface of the super hydrophobic fiber material is a super hydrophobic structure composed of the nano material, and the nano material and the fiber material are connected via Van der Waals' force. The invention also provides the super hydrophobic fiber material. In the preparation method, no binding agent is added, the super hydrophobic structure can be formed on the fiber material without surface treatment with fluorine-containing low surface energy materials, and connection of the super hydrophobic surface with the fiber material is firm, and falling is not easily caused.

Description

technical field [0001] The invention relates to a superhydrophobic fiber material and a preparation method thereof. Background technique [0002] Superhydrophobic materials have attracted much attention due to their special wettability. Superhydrophobic surfaces have potential applications in self-cleaning surfaces, oil / water separation, oil transportation, microfluidic systems, and biocompatibility. The formula summarized by Wenzel and Cassie has become the basis of the current research model of superhydrophobicity, indicating that the superhydrophobicity exhibited by materials is determined by the surface energy of the material and its microscopic geometric shape and arrangement. At present, people have been able to use many methods to obtain superhydrophobic materials, and have been applied to a certain extent. However, in the preparation process of these studies, materials with low surface energy such as fluorine are usually used to modify the material to obtain a super...
