Abstract

The invention relates to a method for preparing a hydrophobic lipophilic cotton fabric material through structuring a zinc oxide fine structure. The method comprises the following steps of: combining a sol-gel method with a hydrothermal method, i.e. uniformly laying prepared zinc oxide nano seed crystals on the surface of a cotton fabric through utilizing the sol-gel method at first, then growing zinc oxide nanorods toward fixed directions on the surface of the cotton fabric through utilizing the hydrothermal method, finally, modifying the cotton fabric through utilizing long-chain fatty acid-palmitic acid so as to have superhydrophobicity, and wrapping cotton with the cotton fabric for oil absorption. According to the method, the specific structure of zinc oxide is utilized to structure the superhydrophobic cotton fabric surface, and moreover, the cotton fabric has lipophilicity, good oil absorption after wrapping the cotton and a good practical application value in petroleum pollution water body remediation.

Description

technical field [0001] The invention relates to a method for preparing a hydrophobic and lipophilic cotton fabric material, in particular to a method for preparing a hydrophobic and lipophilic cotton fabric material by constructing a zinc oxide microstructure. Background technique [0002] In nature, superhydrophobic phenomena are ubiquitous, and the most typical example is the surface of various plant leaves represented by lotus leaves. Hydrophobic surfaces have attracted widespread interest. In addition to the leaves of plants, the bodies of many animals have superhydrophobic properties, such as the wings of butterflies and the feathers of waterfowl. The urgent need for functional materials has drawn great attention to the application of microstructures in life science and material science, and the relationship between microstructures and wettability of solid surfaces has aroused widespread interest among scientists. Superhydrophobicity is an extreme special case of surf...
