由于近年来超导技术的发展，强磁场的利用变得容易，抗磁材料和顺磁材料在强磁场中的行为也得到了积极的研究。由于有机纤维、碳纳米管、氮化硼、氧化铝和碳化硅等抗磁材料的磁化率各向异性，利用强磁场使这些材料沿一定方向排列成为可能。通过在单体基质中分散抗磁性填料，然后在强磁场中对其进行取向和聚合，可以制备出各向异性功能复合材料。当使用功能性抗磁填料时，可以生产出力学、热、电性能等各向异性良好的复合材料。
As a result of the development of recent superconductive technology, a high magnetic field would be able to be easily utilized, and the behavior of diamagnetic material and paramagnetic material in a high magnetic field are actively studied.Due to anisotropy in magnetic susceptibility of diamagnetic materials such as organic fiber, carbon nanotubes, boron nitride, aluminium oxide and silicon carbide, it is possible to align these materials in a certain direction using a high magnetic field. The anisotropic functional composite material can be prepared, by dispersing diamagnetic filler in the monomer matrix, followed by its alignment in a high magnetic field and polymerization of the matrix. The composite which is excellent in the anisotropy of mechanical, thermal, electrical properties, etc. can be produced, when a functional diamagnetic filler is used.
