水热法制备锰锌铁氧体/碳纳米管磁性材料
Hydrothermal synthesis carbon nanotubes coating with Mn0.5Zn0.5Fe2O4 magnetic materials
摘要
Abstract
The magnetic composite of carbon nanotube coating with Mn0.5 Zn0.5Fe204 nanoparticles was synthesized by a hydrothermal synthesis method with low cost and pollution. The composite was characterized by XRD, TEM, HRTEM, FTIR and VSM. The XRD results confirmed that about 180 t was found to be an appropriate hydrothermal temperature to obtain Mn0.5Zn0.5 Fe2O4/MWNTs magnetic composites. The composites contained Mn0.5Zn0.5Fe2O4, MWNTs and a little γ-Fe2O3. γ-Fe2O3 still coexisted in the composites while the hydrothermal temperature increased. TEM results and HRTEM results showed that the Mn0.5 Zn 0.5Fe2O4 nanoparticles were round, and the size of the Mn0.5 Zn0.5 Fe2O4 nanoparticles were 10-20 nm. The carbon nanotube attached carboxylic and phenolic groups without coating, and MnZn-ferrite vibrational peaks were shown at 570 cm-1 and 1 388 cm-1 in composite according to the results of FTIR. A test of magnetic properties indicated that the composite was ferromagnetic with a saturated magnetization of 1 145 364 A/m, a remanence of 438 517 A/m and a coercive of 30 361 A/m.关键词
