碳纳米管与硅胶表面引发不朽聚合的性能比较研究

ue to their highly catalytic activity, the bifunctional cobalt catalysts in conjunction with MTBD was introduced in the copolymerization between the functional multi-walled carbon nanotubes (MWNTs), silica gel nanoparticle and highly steric group cyclohexene oxide and CO2 in this paper．The surface-initiated immortal CO2/propylene oxide copolymerization was carried out on the surface of oxidized carbon nanotubes and silaca gel nanoparticle by the rapid and reversible chain transfer under the general condition．The results reviewed that the functionalized nanotubes and silica gel nanoparticle could be easily soluble in organic solvents, the PC coatings on the surface of the individual MWNTs and silica gel nanoparticle are uniform．The flexibility, the electrical conductance and the mechanical properties are improved greatly according to the films grafted with nanotubes and silica gel nanoparticle. The functional carbon nanotubes played the important role in the property enhancement in the PPC matrix and the thermal stability of that is increasing with the addition of functionalized MWNTs．But for silaca gel particle, almost all performance are less than that of MWNTs.
