Abstract

The invention discloses a bionic surface structure for capturing micro-nano particles. Bionic bowl-shaped projection unit and hourglass-shaped embedded pit structure composite structures are distributed on the surface of a component. Bionic bowl-shaped projection units comprise pits, lower portions of the pits are communicated with pores which are communicated with lower portions of hourglass-shaped embedded pit structures, and centers of the bionic bowl-shaped projection units are provided with pores. The bionic bowl-shaped projection units are inclined, and necks of the hourglass-shaped embedded pit structures are provided with gaps. The micro pores in centers of the bionic bowl-shaped projection units and gaps in bottoms of the bionic bowl-shaped projection units and the hourglass-shaped embedded pit structures are beneficial to capturing of the micro-nano particles, and the micro-nano particles are enabled to enter bottoms of the hourglass-shaped embedded pit structures. By the bionic surface structure, micro-nano particle capturing efficiency can be improved.

Description

Technical field [0001] The invention relates to a surface structure, in particular to a bionic surface structure for capturing micro and nano particles. Background technique [0002] With the rapid development of my country's economy, many places across the country have been shrouded in smog in recent years, and the emission of fine particulate matter PM2.5 (particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere) such as sulfur dioxide, nitrogen oxides and volatile organic compounds has increased significantly. Smoggy weather tends to lower the visibility of the air, which in turn causes traffic jams and frequent traffic accidents. At the same time, some micro-nano-scale harmful substances in the air can enter the blood through the respiratory tract and lungs, seriously endangering human health. At present, the elimination of haze is mainly through artificial rainfall, spraying haze absorbent materials in the air, and building ventilation corridor...
