23 Jul Preparation method of CA/CS/CNTs (cellulose acetate/chitosan/ carbon nano tubes) composite nano fiber with good biocompatibility
Abstract
The invention relates to a preparation method of a CA/CS/CNTs (cellulose acetate/chitosan/ carbon nano tubes) composite nano fiber with good biocompatibility. The method comprises the following steps: (1) compounding a CA solution, and preparing nano fiber film by an electrostatic spinning process; (2) carrying out vacuum drying on the prepared nano fiber film; (3) compounding CS and carbon nano tube assembly liquid; (4) assembling; (5) drying the assembled composite film material at 80 DEG C for 12 hours for later use. The nano fiber prepared by the invention has high porosity and good biocompatibility, and promotes cell propagation and albumen adsorption after being added to multi-wall carbon nano tubes, the preparation method of the prepared material is simple and easy to operate and the prepared material has broad use in tissue engineering.
