Hordein electrospun ultra-thin fibers are unstable in an aqueous environment. Chitosan was added to improve their water resistance. With increasing chitosan concentration, the viscosity and conductivity of the biopolymer blends increased, and the surface tensions remained almost constant. The structure and morphology of composite biopolymer fiber membranes showed that the average fiber diameter varied with chitosan concentration. ATR-FTIR spectra showed that the C–H stretching band changed or disappeared with increased chitosan. X-ray diffraction showed that chitosan was distributed in hordein fibers without crystallites. Compared with the hordein nanofibers, thermogravimetric analysis and derivative thermogravimetry curves showed that hordein/chitosan electrospun fibers had slightly decreased thermal stability. In conclusion, a low chitosan content improved the water resistance and other properties of hordein fibers, without changing their morphology or structure.

大黄素静电纺超细纤维在水性环境中不稳定。加入壳聚糖以改善其耐水性。随着壳聚糖浓度的增加，生物聚合物共混物的粘度和电导率增加，并且表面张力几乎保持恒定。复合生物聚合物纤维膜的结构和形态表明，平均纤维直径随壳聚糖浓度的变化而变化。ATR-FTIR光谱显示，CH-H拉伸带随着壳聚糖的增加而改变或消失。X射线衍射表明，壳聚糖分布在没有微晶的大麦醇溶蛋白纤维中。与大麦醇溶蛋白纳米纤维相比，热重分析和导数热重曲线显示大麦醇溶蛋白/壳聚糖电纺纤维的热稳定性略有下降。结论，
