Preparation of Fe3O4 Nanopieces and Modification Tribological Property of Liquid Paraffin as Its Additive

摘要

@@1.Introduction The grain size, morphology, surface state, and microstructure of nanostructured metals directly affect their physico-chemical properties and applications. At present, morphology-controlled synthesis and application research of nano-metal are still at the starting stage. Therefore, it has been profound theoretical significance and application value in there. Having the compatibility with biological tissue, electricity and magnetic property concerned its size and morphology, nano-Fe3O4 has wide applications[1-2]. Monodispersitive particles, octahedron, nanorods, nanowires, nanochains, nanotubes, nanocone array, hollow microspheres, tridimensional superlattices, nanoflowers, and other nanostructure Fe3O4 have been prepared by all kinds of physical and/or chemical methods[3-5]. However, the preparation of two-dimensional nanopieces Fe3O4 was thought difficulty for its antispinel structure and inherent magnetism[6]. There is still little research on the certain morphology nano-Fe3O4 modifying tribological property of lubricating oil as its additive.
