静电纺再生丝素蛋白/明胶共混纳米纤维膜的制备及性能研究

he electrospinning of regenerated silk fibroin (SF) and gelatin (GE) blended with the composition ratio (100/0, 75/25, 50/50, 25/75, 0/100) was performed with hexafluoroisopropanol as spinning solvent. The influence of different composition ratio on the morphology, pore size, microstructure, thermal stability and mechanical properties of SF/GE blend nanofibrous membranes was investigated in this paper. The results showed that: with the GE content increased, the average diameter of the SF/GE fibre was increased, the pore size of the SF/GE blend nanofibrous membranes was slight increased, the blends have no effect on the molecular structure, the thermal stability was improved, the tensile strength was decreased, the elongation at break was increased and the Young's modulus was reduced gradually.
