Preparation of Durable Superhydrophobic Surface Material and Its Application in Packaging

摘要

To study the technical principle of superhydrophobic surface preparation, research progress and application prospect in durability performance. This article reviews and proposes four types of technical methods to improve the durability of superhydrophobic: superhydrophobic surface with self-healing function, SLIPS surface, micro-nano structure with shape memory and mechanical strength of surface micro-nano structure itself, and the application prospect of its use as packaging material is analyzed. The superhydrophobic properties of the surface depend on the surface composition and surface micro-nano multistage structure. The low mechanical strength of the micro-nano multistage structure leads to poor durability of the superhydrophobic performance. Enhancing the durability of superhydrophobic properties on the surface is the prerequisite for the application of superhydrophobic materials on the surface, and it has great application prospects in terms of packaging materials.
