在高温高压条件下利用高压合成装置合成了二维R相C60聚合物,并利用X射线衍射(XRD)和超量子干涉(SQUID)对合成的样品进行了研究.X射线衍射(XRD)数据表明,在6 Gpa压力和700℃-725℃的温度条件下合成的聚合物为纯度较高的二维R相C60聚合物,当温度升高至800℃时,富勒烯的笼状结构塌陷,样品全部变为无定形碳结构.超量子干涉(SQUID))数据表明,在富勒烯笼状结构出现破缺或共价键结构出现断裂的边界条件下制备的二维R相C60聚合物具有铁磁性,样品的磁性来源于破缺的C60分子笼和断裂的共价键.
A two-dimensional R-phase C60 polymer was synthesized by high-pressure synthesis at high temperature and high pressure, and the synthesized samples were characterized by X-ray diffraction (XRD) and superquantum interference (SQUID) , The polymer synthesized under the conditions of 6 Gpa pressure and 700 ℃ -725 ℃ is a two-dimensional R-phase C60 polymer with high purity. When the temperature rises to 800 ℃, the cage structure of fullerene collapses, The samples all turned into amorphous carbon structures.Super Quantum Interference (SQUID) data showed that the two-dimensional R-phase C60 polymer prepared under the boundary conditions of breaking of the fullerene cage structure or breaking of the covalent bond structure has Ferromagnetism, the magnetic properties of the sample from the broken C60 molecular cage and broken covalent bond.
