摘要
采用溶剂热法在短切炭纤维表面均匀负载了磁性纳米粒子,并通过场发射扫描电子显微镜、X射线能谱仪、X射线衍射仪、X射线光电子能谱仪、振动样品磁强计等仪器对短切炭纤维负载磁性纳米粒子前后的样品进行表征。研究结果表明:采用乙醇为溶剂的溶剂热法,在240℃下以乙酰丙酮铁为铁源,成功地在短切炭纤维表面负载了γ-Fe_2O_3纳米粒子而得到磁性短切炭纤维,γ-Fe_2O_3粒子在磁性短切炭纤维表面分布均匀,呈球形,其(311)晶面晶粒尺寸为12.7 nm,在磁性短切炭纤维中的含量为5.77%;磁性短切炭纤维具有1.2 emu/g左右的饱和磁化强度,且能够在弱磁场(≤0.12 T)诱导作用下,在乙醇分散液中沿磁场方向排列取向。
In this paper, magnetic nanoparticle was uniformly loaded on the surface of chopped carbon fibers by solvothermal method. The chopped carbon fiber samples before and after loading magnetic nanoparticles were characterized by field emission-scanning electron microscope, energy dispersive X-ray spectrometers, X-ray diffractometer, X-ray photoelectron spectroscopy and vibrating-sample magnetometer. The results showed that the magnetic γ-Fe2O3 nanoparticles loaded on the chopped carbon fibers were obtained at 240 ℃ by the solvothermal method using ethanol as the solvent and iron acetylacetonate as iron source. γ-Fe2O3 nanoparticles with the content of 5.77% were spherical, and uniformly distributed on the surface of the chopped carbon fibers with a（311） crystal grain size of 12.7 nm. The magnetic chopped carbon fiber had a saturation magnetization of about 1.2 emu/g, and can be aligned in ethanol dispersion along the direction of the magnetic field in the weak magnetic field（≤0.12 T）.
