摘要/Abstract

摘要： 将不同质量比的丝素蛋白（SF）/醋酸纤维素（CA）溶于甲酸中，配置成共混溶液进行静电纺丝，得到SF/CA共混纤维毡。利用SEM、XRD对其结构进行测试表征。结果表明：SF中添加少量CA(<10%)，SF的可纺性显著提高，添加10%CA时，可纺性最好，所得共混电纺纤维细且均匀，直径为50～300nm；CA添加量大于30% 时，可纺性恶化，出现大量的珠状物，且纤维粘连、不连续，形成树枝状结构。XRD分析表明，添加少量CA(<10%)能诱导SF分子构象由无规卷曲向β折叠转变，但CA添加量大于30%时，SF与CA两者分相。

Abstract: The blend solution prepared by dissolving Silk fibroin (SF) and cellulose acetate (CA) in formic acid at different mass concentrations was electrospun into SF/CA blend fibers and then processed into SF/CA felt. The SF/CA fiber felt was studied by SEM and XRD. The results showed that the spinnability of SF was remarkably improved with a small quantity of CA (no more than 10%), and the blend fibers were fine and uniform with the fiber diameters ranging from 50 nm to 300 nm. When CA content was 10%, the SF/CA blends showed excellent spinnability without any beads or droplets. However, the spinnability of SF/CA deteriorated seriously when the content of CA was more than 30%, and the electrospun SF/CA blend nanofibers were discontinuous, sticky, and forming dendritic structure with lot of beads. The XRD analysis showed that adding a small quantity of CA (no more than 10%) could induce the conformation transition of SF molecules transforming from random coil to β-sheet. Nevertheless, the phase separation was observed between SF and CA in blend nanofibers when the content of CA was more than 30%.
