23 Jul Medical silk paper and preparation method thereof
Abstract
The invention discloses a piece of medical silk paper and a preparation method thereof, and belongs to the field of biological medical materials. The medical silk paper is provided with a multilayer reticular structure, and the preparation method comprises the following steps: (1) treatment of natural silk raw materials (degumming, drying and crushing); (2) soaking paste, that is the product obtained in the step (1) is immersed in an alkali solution; (3) pulp washing, that is the product obtained in the step (2) is washed with a large amount of water; (4) aftertreatment, that is the product obtained in the step (3) and a certain amount of a collagen solution are mixed, and the medical silk paper is prepared by the steps of screen mesh paper making, paper rolling, drying, etc. The method has the advantages of simple process, energy saving and emission reduction, and low production cost, and is suitable for industrial production. The prepared silk paper has the advantages of controllable degradability, good biological compatibility, good water absorption, and good plasticity; the mechanical intensity satisfies clinic requirements of medical membranes, and has wide application prospects in the fields of wound dressings, tissue engineering, medicament controlled-release carriers, etc.
