采用静电纺制备了不同质量比的玉米醇溶蛋白(Zein)/聚乙烯醇-苯乙烯吡啶盐(PVA-SbQ)复合纳米纤维,在紫外光照射下得到光交联 Zein/PVA-SbQ复合纳米纤维。利用扫描电镜(SEM)对复合纳米纤维的形貌和直径分布进行了分析；傅里叶变换红外光谱(FT-IR)曲线表明,Zein/PVA-SbQ 复合纳米纤维保持了两组分原有的化学功能基团；通过差示扫描量热仪(DSC)研究了复合纳米纤维的热学性能,结果表明其具有较高的热稳定性；静态接触角(CA)测试说明,随着 PVA-SbQ 比例增大复合纳米纤维疏水性降低；强力测试表明,PVA-SbQ的加入增大了 Zein 纳米纤维的强度。
Zein/PVA-SbQ composite nanofibers blend with different mass ratios were fabricated by electrospin-ning.Then the nanofibers were irradiated under UV light to get the cross-linked ones.The morphologies and di-ameter distributions of Zein/PVA-SbQ composite nanofibers were observed by SEM.The spectra of FT-IR indi-cated that two compositions of composite nanofibers maintained their own original functional groups.The ther-mal properties of composite nanofibers were studied by DSC,the results from characterizations revealed that the composite nanofibers still maintained superior thermal stability with the addition of PVA-SbQ.The results of CA elucidated the hydrophobicity decreased for composite nanofibers with increasing PVA-SbQ composition. The strength test showed that the addition of PVA-SbQ increased the tensile strength of composite nanofibers.
