静电纺丝法制备PEO/Fe_3O_4磁性纳米纤维
|
摘要
以聚氧化乙烯(PEO)为聚合物纺丝原料、卵蛋白粉(LDB)为分散剂,通过静电纺丝技术制备一系列不同四氧化三铁(Fe_3O_4)含量的Fe_3O_4/PEO复合纳米材料。经傅里叶红外光谱仪测试,显示纳米复合材料中存在Fe_3O_4。采用数显黏度计、导电率仪和扫描电子显微镜对制备的复合纳米材料的形态及物相组成进行表征,并分析了Fe_3O_4的加入对复合纳米材料可纺性的影响。结果表明,PEO与Fe_3O_4比例为10∶3时,复合纳米材料的可纺性最好,纤维平均直径达110 nm。
PEO / Fe_3O_4 composite nanofiber with different Fe_3O_4 content is prepared by electrospinning technology using PEO as a feedstocks and LDB as a dispersant. Fourier transform infrared spectroscopy( FTIR- 650) proves that there is Fe_3O_4 nanoparticle in the nanocomposite. The morphology and object composition of composite nanomaterial are characterized by digital viscometer( NDJ- 8S),conductivity meter( DDS- 307) and scanning electron microscopy( SEM). The influence of Fe_3O_4 on the spinnability of nanocomposite is analyzed. The results show that when the ratio of PEO / Fe3O4 is 10 ∶ 3,the nanocomposite features good spinnability with average fiber diameter of 110 nm.
