Synthesis of carbon nanotubes/polyacrylamide nanocomposites with improved load-carrying capacity and antiwear ability

摘要

In this study, the functionalized carbon nanotubes (CNTs) were prepared and used for the first time as a high-efficient dispersant for the synthesis of CNTs/polyacrylamide nanocomposites via dispersion polymerization. The results showed that the functionalized CNTs not only could be use as an effective solid stabilizer for dispersion polymerization but also could be homogeneously dispersed into the production of polyacrylamide as nanofillers by this method. Furthermore, the functionalized CNTs/polyacrylamide nanocomposites can be dissolved in water and can effectively improve the load-carrying capacity and antiwear ability of base stock as a good lubricant additive in water-based fluid.
