23 Jul Degradable skin tissue engineering bracket material and preparation method thereof
Abstract
The invention discloses a material in the field of biomedical tissue engineering, in particular a method for preparing a skin tissue engineering bracket by adopting polysaccharide substances in nature and utilizing a blending method. The method comprises the following steps that: a glycerol solution of II-type collagen and a protonation solution of chitosan are first prepared respectively, evenly blended, added with quantitative konjak glucomannan fine powder and continually stirred to be sol; a gel sample is put into a vacuum foam-removing device for foam removal, taken out, kept to stand and poured into a die; and a film is formed, dried at a constant temperature and then taken off. The material is a polymer material applied to skin or nerve repair, and the prepared film is ideal in mechanical properties, degradation performance, water absorption and steam transmission coefficient. The invention relates to a degradable skin tissue engineering bracket material and a preparation method thereof.
