| 英文摘要 | graphene oxide (go) sheets were first synthesized through oxidation of natural graphite by a modified hummers method, and then their homogeneous and stable dispersion in n, n'-dimethylformamide (dmf) was obtained. stable and homogeneous solution mixtures of go and paa (polyamic acid) in dmf at different mass ratios of go/paa were readily prepared. uniform composite films of go-faa were subsequently prepared by solution casting. faa was turned to polyimides (pt) and go reduced in situ to grapheme (gs) at the same time by a subsequent thermal imidization of go-faa films, leading to composite films of gs-pi. electrical resistivity, thermal stability and mechanical property of gs-pi films were studied. the results indicate that the surface resistivity of gs-pi films was significantly decreased with the increase in gs content,lowered to about 10(6) omega, the standard of the anti-static electricity film, in the film prepared with 1.0 wt% of go in go-paa. the tensile strength and the elongation at break of gs-pi composite films were both increased with increase in gs content, reached their maxima in the film prepared with 0.6 wt% of go in go-paa, followed by regular decreases with further increase in gs. different from the tensile strength and the elongation at break, the tensile modulus of gs-pi was in constant increase with gs content in the film. an increase of 37% was detected in gs-pi film prepared with 3.0 wt% of go. moreover, the ductility and the thermal stability of gs-pi were well kept in all the composite films regardless of its gs content. |
