Abstract:
The present invention discloses a method for preparing a double-network hydrogel tube with a complex structure. Iron wires of different sizes are mechanically polished, arranged in different manners, and then immersed into a monomer prepolymer solution, or a monomer prepolymer is poured into a container containing iron wires of different arranged shapes to conduct a polymerization reaction, such that a uniform primary-crosslinked single-network hydrogel film can be rapidly grown on the surface of each iron wire. The hydrogel film is then immersed in a secondary-crosslinking solution for secondary crosslinking to build a double-network hydrogel film. After immersion processing, the wires are drawn out to obtain high-strength hollow double-network hydrogel tubes of different shapes. The hydrogel tube has a diameter of 10 micrometers to a few millimeters, the shape of the tube inner structure is highly controllable, and the tensile strength of the hydrogel tube can be up to 2 MPa.

Claim (Index 4):
The method according to  claim 2 , wherein in the monomer prepolymer solution, the mass fraction of the monomer, the initiator and the crosslinking agent is from 5% to 15%, the molar ratio of the three is 500-1000:1:0.5, the mass fraction of the biomacromolecule is 0.1-1%, and the balance is deionized water.
