【 摘 要 】

Carbon nanotubes (CNTs) were unzipped using the modified Hummer method to prepare the CNTs-GO microstructure (see Fig. 1). A new type of CNTs-GO-H20 nanocomposite has been synthesized by grafting hyperbranched (HB) polyester (Boltorn H20) brushes on the CNTs-GO by coupling agent (KH560). The morphology of CNTs-GO-H20 was characterized by FTIR, TEM, XPS and TGA. The FT-IR data and XPS data evidenced that CNTs-GO-H20 nanocomposites were synthesized successfully. The addition of CNTs improved the thermal stability of the nanocomposites. The TEM data showed that the CNTs-GO microstructure was also prepared. These electrochemical measurements results indicated that coatings provided greater protection against corrosion behavior. Moreover, the nanocomposite material improved corrosion resistance of the coating.
