Substrate material coated with polymer needled tufts of natural-Opuntia-microdasys-plant-like structure

Abstract

The invention relates to a substrate material coated with polymer needled tufts of a natural-Opuntia-microdasys-plant-like structure and a preparation method thereof. The substrate material is composed of a plurality of polymer needled tufts fixed on a porous hollow three-dimensional substrate material having gradient wettability, wherein each polymer needled tuft is composed of a plurality of polymer main needles of which the roots are fixed together; each polymer main needle has needled structure characteristics owned by plants such as natural Opuntia microdasys; and the external surface of the porous hollow three-dimensional substrate material having gradient wettability is hydrophobic, and the internal surface is hydrophilic. The polymer needled tufts can efficiently collect micro liquid drops in the air and change the liquid drops into utilizable fresh water, and the collected water can be transferred by the substrate material having gradient wettability from the hydrophobic side of the external surface of the substrate material to the hydrophilic side of the internal surface, so that the water collection efficiency of the substrate material coated with polymer needled tufts of an Opuntia-microdasys-plant-like structure (a natural-cereus-plant-like structure) is greatly improved.

Description

technical field

[0001] The invention relates to a bionic water-collecting polymer needle-punched cluster, in particular to a base material of a polymer needle-punched cluster planted with a structure imitating a natural palmate plant and a preparation method thereof. Background technique

[0002] Water is the source of life. With the continuous growth of population and the continuous development of human economy, water consumption is also increasing year by year. The supply of water resources has become one of the decisive factors for the rapid economic development of countries all over the world. According to the World Food and Agriculture Organization, about 1.2 billion people, nearly one-fifth of the world's population, live in areas of physical water scarcity, and another 500 million people are approaching this situation. In addition, the shortage of potable water caused by irrational use such as pollution and waste is even more urgent. At present, about 884 million peop...
