Ultra-hydrophobic film of thermoplastic substrate

Abstract

The invention discloses a super-hydrophobic film for a thermoplastic matrix, which comprises a thermoplastic film matrix and a super-hydrophobic layer. The super-hydrophobic layer consists of micro-scale powder particles and nano-scale powder particles arranged at intervals and embedded into the film matrix, and the micro-scale powder particles and the nano-scale powder particles form micro-scale protrusions and nano-scale protrusions on the surface of the thermoplastic film matrix and have low surface energy or are modified by low surface energy substances. The super-hydrophobic film has the advantages of simple structure, easy preparation and lower cost; a water contact angle of the super-hydrophobic layer is between150 and 165 degrees, and a roll angle is less than 5 degrees; the super-hydrophobic film also has the advantages of stable performance, low cost and excellent mechanical property, and can be applied to the occasions needing water proofing, pollution prevention, mist resistance, snow cover resistance, ice coating resistance, oxidation prevention and the like; when the thermoplastic film matrix is adopted, the super-hydrophobic film can be flexible to use, can be manufactured into an adhesive tape structure to be adhered on the surface of other matrixes, and is convenient and simple to use; and by adopting a hot pressing method for preparation, the thermoplastic film matrix and the super-hydrophobic layer are firmly combined, and the preparation method is simple and easy to operate and has low manufacturing cost.

Description

technical field [0001] The invention relates to a superhydrophobic structure, in particular to a superhydrophobic film of a thermoplastic matrix. Background technique [0002] Surface wettability is an important property that determines the application of materials. Many physical and chemical processes, such as adsorption, lubrication, adhesion, dispersion, and friction, are closely related to surface wettability. Research on superhydrophobic surfaces has attracted great attention due to their potential applications in self-cleaning surfaces, microfluidic systems, and biocompatibility. The so-called super-hydrophobic surface generally refers to the rolling angle of water droplets with a contact angle of greater than 150° and less than 10°, which is waterproof, anti-icing, anti-fog, anti-snow, anti-fouling, dust-proof and prevents transmission lines from being caused by water droplets. Corona noise and other features. Therefore, it has broad application prospects in the fie...

AI Technical Summary

Problems solved by technology

[0004] Most of the methods for preparing superhydrophobic surfaces in the prior art require the use of complex and expensive instruments and equipment and strict control of the preparation process. The cost of superhydrophobic structures is relatively high and cannot Realizing large-scale application of superhydrophobic surfaces

At the same time, the preparation cost is relatively high, and the mechanical strength of the prepared superhydrophobic surface is not high, which cannot meet the actual needs.
