23 Jul Soft tissue engineering porous scaffold and preparation method thereof
Abstract
The invention discloses a soft tissue engineering porous scaffold and a preparation method thereof. The soft tissue engineering porous scaffold is prepared by compositing sodium carboxymethylcellulose, chitosan and polyvinyl pyrrolidone, wherein the mass ratio of the sodium carboxymethylcellulose to the polyvinyl pyrrolidone ranges from 1:50 to 1:0.1, the mass ratio of the sodium carboxymethylcellulose to the chitosan ranges from 1:50 to 1:0.1, the thickness of the porous scaffold is 0.8 to 2.6mm, the porosity is 35.0% to 87.0%, and the tensile strength is 1.4MPa to 68.98MPa. The preparation method of the scaffold is environmentally friendly and non-toxic, the procedure of the preparation technology is simple, the cost is low, and the prepared scaffold is good in biocompatibility, can replace an artificial skin, is used as skin dressing and a skin tissue engineering material, and helps a patient with a large-area and deep skin burn to recover physiological functions lost because of skin injury under the condition of insufficient autologous skin.
