Abstract： |
The present invention relates to the preparation process of natural nanometer fiber for tissue engineering, air filtering, clothing material and composite reinforced aeronautical and astronautical material, and is especially the preparation process of natural nanometer spider silk fiber and cocoon silk fiber. Through soaking in certain solution and ultrasonic dissociation, natural nanometer fiber of diameter 30-100 nm may be prepared. The prepared natural nanometer fiber may find its wide application in tissue engineering, air filtering, clothing material and composite reinforced aeronautical and astronautical material. The present invention has simple operation, simple equipment, low power consumption and low cost, and is suitable for both lab preparation and industrial production. |
