Abstract

The invention discloses an efficient, low-cost and pollution-free preparing method of polymer hydrophobic surfaces. The efficient, low-cost and pollution-free preparing method adopts the following steps: 1, making an impressing mould: 1.1, adopting a plate material to make a mould base plate; 1.2, washing the mould base plate, and then, carrying out air-drying; and 1.3, adopting laser machining equipment to machine micro-structural patterns on the surface of the mould base plate; and 2, carrying out ultrasonic impressing coping on polymer films by adopting ultrasonic impressing equipment and utilizing the impressing mould made in the step 1 to obtain the hydrophobic surfaces with micro-and-nano double structures. When the laser machining and ultrasonic impressing combined machining methodis used for preparing the polymer hydrophobic surfaces, short time is spent, the cost is low, and the whole process is green and free of pollution due to the zero adding of fluorine containing agents.Besides, the polymer hydrophobic surfaces prepared by using the method have great durability, stability and wear resistance, is suitable for large-scale production and manufacture and has wide application prospects.

Description

technical field

[0001] The invention belongs to the field of micro-nano technology, and relates to a method for preparing a polymer hydrophobic surface with high efficiency, low cost and no pollution. Background technique

[0002] Hydrophobic technology is a new type of technology with special surface properties, which can be applied in many fields in real life, such as self-cleaning, anti-corrosion, preventing current conduction, surface self-protection and other fields. With the continuous progress of the times, the preparation of hydrophobic surfaces has become a research hotspot today.

[0003] The most notable feature of ultrasonic imprinting technology is that it does not require additional heat sources and local heat generation. Ultrasonic imprinting has the advantage of reduced cycle times and lower energy consumption due to localized heat generation in specific areas. However, polymer materials provide a new option for the fabrication of microstructures and microd...
