Abstract

The invention relates to a spider silk-like polymer fiber in the field of chemical biomimetic technology, a preparation method and application thereof. The spider silk-like polymer fiber comprises a matrix polymer and particulate additives dispersed therein, the particulate has an average particle size of 0.1-1000 microns, and the polymer fiber has a fiber body comprising a fiber body and a fiber body A spider silk-like microstructure of spindle-knot structural units distributed at intervals, wherein the spindle-knot structural units contain the microparticles, and the radial height of the spindle-knot structural units is greater than the diameter of the fiber main body. The preparation method of the polymer fiber of the present invention does not need to greatly modify the existing spinning process, and the equipment does not need to be modified, the process is simple, and the cost is low. The obtained spider silk-like polymer fibers can realize directional movement of water droplets on the surface of the fibers, thereby having a water-collecting function and can be used to prepare water-collecting materials.

Description

Technical field [0001] The present invention relates to a biomimetic chemical technology, and more particularly, to a class of spider silk polymer fibers, their preparation and their use. Background technique [0002] Water is an important natural resource development of human society. Earth's water, despite the huge number, but it can be used directly in the production and life of people rarely, only about 0.26% of the total water volume of the Earth. Sustainable use of water resources is to use the most important question of all natural resources for sustainable development. Today, the shortage of fresh water resources is emerging. About 15 million people in more than 80 countries around the world face a shortage of fresh water, of which 300 million people in 26 countries live in a completely dry state. By 2025, the world will have 30 million people short of water, involving up to more than 40 countries and regions. Fresh water shortage has restricted the development of society...
