Reinforcing efficiency of epoxy resin by 4-(aminophenoxy)benzoyl-functionalized carbon nanomaterials |
| 초록 |
Epoxy resin-based carbon nanotube (CNT) composites have been extensively investigated due to the potential for industrial/technological applications. To covalently attach more reactive functional groups onto the surface of carbon nanomaterials such as vapor-grown carbon nanofibers (VGCNF) and multi-walled carbon nanotubes (MWNT), 4-(4-aminophenoxy) benzoic acid was prepared. VGCNF and MWNT were functionalized with 4-(aminophenoxy)benzoic acid in polyphosphoric acid (PPA)/phosphorous phentoxide (P2O5) medium via “direct” Friedel-Crafts acylation reaction to afford 4-(aminophenoxy)benzoyl-functionalized VGCNF (APF-VGCNF) and MWNT (APF-MWNT), respectively. They were blended with epoxy resin by simple mechanical stirring in dichloromethane, which was added to help efficient mixing. The resultant composites displayed improved electrical and physical properties. |
