Full carbon hollow cage-like fullerene structure is characterized by alternating single and double bonds, given the a C60 special physical and chemical nature. Prepared containing C60 polymer / inorganic nanocomposites rapid development in recent years, research direction, this is because adding a small amount of C60 can improve the performance of the polymer to the polymer system. However, agglomerates C60 and in general solvent poor solubility and lead to defects in the application, Therefore, by polymerizable modified C60 is an effective method, there is created a class having electrical, magnetic, mechanical, special catalytic, and optical properties of polymer materials. Far, according to C60 grafted to the polymer different method for C60 / polymer synthesis can be divided into the following three categories: (1) the \reaction; (2) \(3) the term \In this paper, a method of in situ polymerization, in a polyphosphoric acid / phosphorous pentoxide (mass ratio 10:1) as the solvent system, 3,3 '- diaminobenzidine (DAB) and 4,4' - dicarboxyphenyl the diphenylether (DCDPE) as monomer, in the presence of C60 (mass fraction of 0.5%, 1%, 2%, 5%), synthetic graft linear polybenzimidazole of C60 nanocomposites and prepared nanoparticles are uniformly dispersed, the macroscopic mechanical better performance of the composite membrane. By infrared (IR), nuclear magnetic resonance (NMR), X-ray diffraction (XRD) characterization methods, X-ray photoelectron spectroscopy (XPS) and so on, has proved polybenzimidazole molecules segment was successfully grafted to the C60, and by a scanning electron microscope The analysis can be seen the to C60 preferably dispersed in the polybenzimidazole matrix; Meanwhile, chemical grafting, and physical blends were prepared C60 / polymer nanocomposites compared found, chemical grafting of the nanocomposite having better dispersibility, as well as mechanical properties. Meanwhile, we also use the vinyl pyrrolidone and 2 - aminoethanethiol, in toluene as the solvent system, the C60-PVP, IR, NMR Graft-to manner and have proved C60 graft; Further, the obtained C60-PVP in the water can be dispersed, improving the C60 solubility, to expand the range of applications of C60, such as the medical and biological fields; And, PVP of no temperature-responsive, while the C60-PVP is the polymerization temperature and pH sensitivity. matter, ultraviolet transmission, and dynamic light scattering method proved its temperature sensitivity.
