The spin ability of flaxseed mucilage (FM) as a new source was evaluated through electrospinning. At various experimental conditions and different solution properties, it was impossible to fabricate FM nanofiber. Thus, polyvinyl alcohol (PVA) was applied as co-polymer to facilitate nanofiber formation. In terms of morphology, FM:polyvinyl alcohol (PVA) nanofiber using a mixture of 3% FM solution and 12% (PVA) solution at ratio of 60:40 was selected as the best sample. The physicochemical properties of the nanofiber was evaluated by scanning electron microscopy (SEM), fourier transform infrared (FTIR), differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA) and X-ray diffraction (XRD). SEM images showed beadless, uniform and smooth nanofibers with an average diameter of 230nm. Based on DSC and TGA results, the thermal stability of the nanofiber was improved by adding PVA. FTIR data revealed that there was no chemical interaction between functional groups of FM and PVA in the nanofiber.
通过静电纺丝评估了亚麻籽胶（FM）作为一种新来源的旋转能力。在不同的实验条件和不同的溶液性质下，无法制备 FM 纳米纤维。因此，将聚乙烯醇（PVA）用作共聚物以促进纳米纤维的形成。就形态而言，选择 FM：聚乙烯醇（PVA）纳米纤维（使用 3％FM 溶液和 12％（PVA）溶液的混合物，比例为 60：40）作为最佳样品。通过扫描电子显微镜（SEM）、傅里叶变换红外（FTIR）、差示扫描量热法（DSC）、热重分析（TGA）和 X 射线衍射（XRD）评估了纳米纤维的物理化学性质。SEM 图像显示出无珠状、均匀且光滑的纳米纤维，平均直径为 230nm。根据 DSC 和 TGA 结果，添加 PVA 可提高纳米纤维的热稳定性。FTIR 数据表明，FM 和 PVA 之间的功能基团在纳米纤维中没有发生化学相互作用。
