23 Jul Skin tissue engineering double-layer film material and preparation method thereof
Abstract
The invention discloses a skin tissue engineering double-layer film material and a preparation method thereof. The preparation method comprises the steps that degradable materials including chitosan and konjac glucomannan which have the good biocompatibility are adopted as raw materials and prepared into mixed solutions separately, film forming is conducted on the mixed solutions through a tape casting method separately, two layers of films are bonded together by adopting a konjac glucomannan solution with the certain concentration as a bonding agent, and then the chitosan-konjac glucomannan double-layer film material is prepared. The material has the advantages of being simple in preparation process, low in cost, adjustable in degradation rate, good in biocompatibility and the like; early cell experiments and animal experiments show that the double-layer film material can be suitable for organisms and is a degradable multifunctional composite material capable of promoting skin repairing.
