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.
