Abstract
Provided is a preparation method for a tube. The method comprises the following steps: a) adding a polymer solution into a poor solvent, such that the polymer diffuses on the liquid level of the poor solvent, so as to obtain a polymer film, wherein the solvent in the polymer solution is dissolved in the poor solvent; b) curling the polymer film on the liquid level of the poor solvent by using a mold to obtain a bar; and c) removing the mold to obtain a tube. The present invention further provides the use of the above tubular as an artificial tubular tissue.

A method for preparing a tubular material, comprising following steps:
- a) adding a polymer solution to a poor solvent to diffuse the polymer into a film on a liquid surface of the poor solvent to obtain a polymer film, wherein the polymer is dissolved in a good solvent to form the polymer solution, and the good solvent in the polymer solution is dissolved in the poor solvent;
- b) rolling, when the good solvent remains in a side of the polymer film not in contact with the poor solvent, the polymer film on the liquid surface of the poor solvent using a mold to obtain a bar material;
- and
- c) removing the mold to obtain the tubular material.
