Fe_3O_4纳米复合粒子研究

STUDY ON Fe_3O_4 NANOPARTICLES COMPLEX

制备了酞菁镍（ＮｉＰｃ）－Ｆｅ３Ｏ４ 纳米复合粒子，研究了其化学稳定性和磁性能。结果表明，ＮｉＰｃ在Ｆｅ３Ｏ４ 纳米粒子表面形成了复合层，并且它们之间形成了一定程度的化学键。ＮｉＰｃ复合层可有效地保护Ｆｅ３Ｏ４ 纳米粒子不被空气氧化，显著提高了其抗氧化能力，并降低了其矫顽力。

Nickel phthalocyanine (NiPc) Fe 3O 4 nanoparticles complexes were prepared and their chemical stability and magnetic property were measured. The results show that NiPc forms complex layers on the surface of Fe 3O 4 nanoparticles and there is somewhat chemical bonding between them. NiPc can protect Fe 3O 4 nanoparticles effectively from oxidizing and improve their antioxidation ability greatly. In addition, H c of NiPc Fe 3O 4 nanoparticles complex is much lower than that of Fe 3O 4 nanoparticles.
