Preparation and Performance of Amphiphilic Random Copolymer Noncovalently Modified MWCNTs/Epoxy Composite
An amphiphilic random copolymer of polyglycidyl methacrylate-co-N-vinyl carbazole P(GMA-co-NVC) was synthesized by free radical polymerization and was used to noncovalently modify multi-walled carbon nanotubes (MWCNTs). The obtained P(GMA-co-NVC)/MWCNTs was mixed with epoxy resin and used to reinfor...

| description | An amphiphilic random copolymer of polyglycidyl methacrylate-co-N-vinyl carbazole P(GMA-co-NVC) was synthesized by free radical polymerization and was used to noncovalently modify multi-walled carbon nanotubes (MWCNTs). The obtained P(GMA-co-NVC)/MWCNTs was mixed with epoxy resin and used to reinforce epoxy resin. Polymer modified carbon nanotubes/epoxy resin composites were prepared by a casting molding method. Tensile test, electrical resistivity test and differential scanning calorimeter(DSC) analysis were used to study the effect of polymer modified carbon nanotubes on the mechanical, electrical, and thermal properties of epoxy resin. The results show that the epoxy composite reinforced with P(GMA-co-NVC)/MWCNTs shows a remarkable enhancement in both tensile strength and elongation at break compared to either the pure epoxy or the pristine MWCNTs/epoxy composites. In addition, the electrical conductivity of epoxy is significantly improved and the volume resistivity decreases from 10<sup>14</sup>Ω·m to 10<sup>6</sup>Ω·m with 0.25% mass fraction loading of P(GMA-co-NVC)/MWCNTs. Moreover, glass transition temperature of the epoxy composite also increases from 144℃ to 149℃. |
