| Abstract: | Carbon nanotubes/polyurethane composites was synthesized by in situ polymerization to modify polyurethane materials.A number of analytical techniques,including Fourier transform infrared spectroscopy(FT-IR)measurement,X-ray photoelectron spectroscopy(XPS)analysis,Scanning electron microscopy(SEM)observation were employed to assess the influence of acid treatment on carbon nanotubes,and mechanical properties of composites of carbon nanotubes and polyurethane were charactered by mechanical analysis,and the influence of acid treated carbon nanotubes on modifying polyurethane materials was compared to raw carbon nanotubes.It indicated that carbon nanotubes could improve the mechanical properties of polyurethane,and the improvement was more significant by acid treated carbon nanotubes. |
| Keywords: | carbon nanotubes polyurethane composites synthesis mechanical properties |
