用丝素进行静电纺,发现使用1,1,1,3,3,3,六氟-2-丙醇(HFIP)作为丝素溶剂,通过装有平行电板作为集丝器的静电防装置,可以制造部分取向非晶结构的丝素纳米纤维。分别通过水蒸气或乙醇处理,优先从非晶转变到高收缩的β-转角形silkⅠ或从非晶转变到反平行的β-层状规则排列silkⅡ,此外,微晶的c轴平行取向于纤维轴。当使用加满乙醇的碟形集丝器进行静电纺时,得到了一种独特的网状组织。这种网状组织似乎是因丝素结晶化引起的收缩和/或因纤维间乙醇液滴的表面张力引起的纤维收缩。在这种纺丝装置上,微晶的c轴也平行取向于纤维轴。
Electrospinning with silk fibroin was used to find that the use of 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) as a silk fibroin solvent by an electrostatic protection device , Can be made partially oriented amorphous structure of fibroin nanofibers. Respectively by water vapor or ethanol treatment, preferentially from amorphous to high-shrinking β-corner silk I or from amorphous to anti-parallel arrangement of regular β-layer silk Ⅱ, in addition, the crystallite c axis parallel to the fiber axis. When electrospinning was performed using a dish-shaped wire feeder full of ethanol, a unique reticular structure was obtained. This reticular tissue appears to be due to shrinkage due to fibroin crystallization and / or fiber shrinkage due to the surface tension of inter-fiber ethanol droplets. In this spinning apparatus, the c-axis of the crystallites is also oriented parallel to the fiber axis.
