利用静电纺丝制备出纳米羟基磷灰石（nHA）/玉米醇溶蛋白（zein）复合超细纤维。通过场发射扫描电镜、透射电镜观察了纳米羟基磷灰石/玉米醇溶蛋白复合超细纤维的形貌;利用红外光谱仪、X射线衍射仪对纳米羟基磷灰石/玉米醇溶蛋白复合超细纤维结构和性能进行表征,并进行了拉伸测试。结果表明,随着超细纤维中羟基磷灰石含量的增加,纤维的直径先减小后增大,纤维中纳米羟基磷灰石的结晶逐渐变好。相比于玉米醇溶蛋白超细纤维,含有质量分数为25%羟基磷灰石的复合超细纤维仍具有较好的力学性能。
Ultrafine nano-hydroxyapatite（nHA）/zein composite fibers were prepared via electrospinning.The morphology of the composite ultrafine fibers was investigated by field-emission scanning electron microscopy（FE-SEM） and transmission electron microscopy（TEM）.The structure and properties were characterized by Fourier transform infrared spectrum（FT-IR） and X-ray diffraction（XRD）.The mechanical properties of fibers were also tested.The results show that the diameter of the fibers firstly decreases then increases,and the crystallinity of nHA in the fibers becomes better with increasing of nHA content in the fibers.Compared with zein fibers,the mechanical properties of ultrafine nHA/zein composite fibers are still well when the nHA content is 25% in the fibers.
