摘　　要：静电纺丝可获得丝素纳米级纤维，并以非织造布状排列，广泛用于细胞支架、伤口包覆及药物控释等。用甲酸溶解丝素室温干燥膜，研究了静电纺丝素纳米纤维非织造膜的形态结构，分析其影响因素。结果表明：非织造膜孔隙率为32．3％，孔径80～600nm；纤维直径与纺丝液质量分数表现出高度显著线性关系，纤维直径随纺丝液质量分数的升高而增大；纤维直径开始随电压的增大而变小，之后变大；电场强度相同。高电压／长距离电场形成的纤维直径小。Electrospinning can prepare silk fibroin nanofibers nowoven membrane used as tissue engineering, wound covering and drug controlled release. The regenerated silk fibroin air-dried membrane was dis- solved in formic acid and electrospun. This paper studied the morphology of electrospinning silk fibroin nanofibers nonwoven membrane and analyzed process influence. The results showed that porosity was 32.3% and the range of porous diameter was 80 ~ 600 nm, fiber diameter represented highly remarka- ble linear relation to concentration, increased with solution concentration, decreased firstly and then increased with its voltage. Higher voltage/longer distance electric field can produce smaller nanofibers diameter.
