Abstract
The invention relates to a spider-silk-like polymer fiber in the technical field of chemical bionics, a preparation method therefor and the use thereof. The spider-silk-like polymer fiber comprises a matrix polymer and a particle additive dispersed therein, wherein the particles have an average particle size of 0.1-1000 microns, and the polymer fiber has a spider-silk-like microstructure comprising a fiber body and spaced spindle knot structural units on the fiber body, wherein the spindle knot structural units comprise the particles, and the radial height of the spindle knot structural units is greater than the diameter of the fiber body. The preparation method of the polymer fiber of the invention does not require greatly modifying the existing spinning processes, and the equipment does not need to be changed, the process is simple, and the cost is low. The obtained spider-silk-like polymer fiber can realize the directional movement of water droplets on the surface of the fiber, thereby having a water gathering function and can be used for preparing water gathering materials.
