METHOD FOR MEANUFACTURING A COMPOSITE COLLAGEN FILM

摘要

A method for manufacturing a composite collagen film. The method includes providing a collagen film and dipping the collagen film in a solution of collagen and glycosaminoglycans (GAGs). The method further includes sequentially performing a freezing process, a vacuum freezing drying process, a condensing process, and a drying process. Finally, the method comprises using a cross-linking agent for making the collagen film cross link with the collagen and GAGs in the solution so as to produce a composite collagen film.
