23 Jul Preparation method of collagen ultrafine membrane material
Abstract
A preparation method of collagen ultrafine membrane material comprises the following steps: 1. dissolving collagen in phosphate aqueous solution, then adding a defined amount of absolute alcohol to prepare a mixed solution while the weight percentage of collagen in the mixed solution is 10-30%; and 2. stirring the above mixed solution at room temperature (about 25 DEG C) to obtain a uniform and transparent mixed solution; and injecting the obtained uniform and transparent mixed solution in an electrostatic spinning device to perform electrostatic spinning and obtain the collagen ultrafine membrane material. The preparation method is simple and the preparation process is environmentally friendly and has no pollution. In addition, the collagen ultrafine membrane material prepared by the method can be crosslinked fast and effectively through common crosslinking methods, thus laying the foundation of developing the material to be the tissue engineering scaffold material or wound coating material.
