日本化学技术研究所最近开发成功使用PVC和活性炭制造有机强磁性体的技术,其磁性比目前公开报道的都高。有机磁性体轻、易加工,近年来美国、苏联对有机磁性体的研究很多、使用芘、苯甲醛为原料已研制成功数种有机磁性体,但还普遍存在着磁化率比较低,只是在-270℃超低温下才具有强磁性体的性质,制备过程 Japan Institute of Chemical Technology recently developed the successful use of PVC and activated carbon to produce organic ferromagnetic technology, its magnetic than the current publicity are high. In recent years, the United States and the Soviet Union have made many researches on organic magnetic materials. Several kinds of organic magnetic materials have been successfully developed using pyrene and benzaldehyde as raw materials, but magnetic susceptibility is still relatively low, 270 ℃ ultra-low temperature magnetic ferromagnetic properties, the preparation process
