Description
Technical field
The present invention relates to chemobionics technical fields, furtherly, are related to a kind of class spider based on column chromatography silica gel
Silk polymer fiber and preparation method thereof.
Background technique
Water resource is the important natural resources of human social development.Tellurian water can direct quilt although enormous amount
People's production and life utilize pitiably little, about only account for the 0.26% of earth total Water.The sustainable use of water resource is
A most important problem in all natural resources Sustainable Development and Utilizations.Today's society, freshwater resources situation in short supply is
Gradually show.About 1,500,000,000 populations of more than 80 countries in the whole world face fresh water deficiency, wherein 26 300,000,000 national populations are lived completely
In exsiccosis.It expects 2025, the whole world will have 3,000,000,000 population water shortages, and the countries and regions being related to are up to more than 40.Fresh water
Shortage of resources oneself through restrict society development, solve the problems, such as that freshwater resources are extremely urgent.Solution may be present in air
In -- here collection be knotted 12.9 trillion tons of vaporous waters -- air is likely to become important " water source " of following mankind's domestic water.
Spider is one of the pioneer that air water source is utilized in nature.When cobweb is placed in moist environment, steam exists
Capture silk table face therein condenses, forms small water droplet；And periodic spindle nodule present in the fiber is configured to capture silk
Radius of curvature generating period variation, generate Laplce's pressure difference, cause water droplet along fiber radial direction unbalance stress, push away
It is mobile that orientation (being directed toward spindle section) occurs for dynamic water droplet.This displacement of water droplet is conducive to droplet quick collecting and forms flood
Pearl weakens transpiration, conducive to the quick collection of moisture in air.Spider collects moisture guarantee in air by the above process
The mode of existence solves fresh water crisis for us and provides new thinking: developing the imitative spider silk fiber with spindle section structure,
The quick collection for realizing moisture in air, has broad application prospects in areas such as desert, islands, is also expected to be used for airport etc.

The polymer filament of catchmenting of imitative spider silk structure a kind of use this kind of method, after existing fiber is immersed Polymer Solution, take
Out in drying process, Polymer Solution hangs on fiber surface since Rayleigh unstability forms a string of drops in fiber surface,
The spindle section of axial alignment is obtained through dry solidification, obtains the fiber of similar spider silk structure.Publication No. CN102587139A
The Chinese patent of (application No. is 201210004686.2), for patent basis, is furthermore achieved with above-mentioned and prepares resulting fiber
Uniform, controllable, surface have more microcosmic protrusion or micropore, improve the collection of fiber the height of the protrusion section on surface from small to large
Water efficiency.This method belongs to the post-processing to existing fiber.
Second is that using electrospinning process, the high requirements on the equipment: Publication No. CN103334244A (application No. is
201710227113.0) Chinese patent discloses a kind of self-assembly preparation method thereof of electrospinning bead string fiber, and the invention is using quiet
Electrospinning forms micron order bead string structure in the surface self-organization of staple fibre, obtains imitative spider silk fiber.But Static Spinning
Costly, and the type of polymer for being able to use electrostatic spinning is less for the equipment of silk.
