| Abstract | The work reports on a nondestructive pathway to produce polymer brush modified carbonnanotubes (CNTs) through surface-initiated polymerization followed by nanoparticleuploading. First, polydopamine layers with high surface coverage were formed on CNTsby spontaneous oxidative polymerization of dopamine. These were then used as the reac-tive layer for subsequent initiator attachment and brush grafting. Atom transfer radicalpolymerization of dimethylamino-ethyl methacrylate was initiated from the initiator layer,resulting in the formation of uniform polydimethylamino-ethyl methacrylate (PDMAEMA)brushes on the CNT surface. These were further quaternized by the reaction with CH3Itoform cationic Quaternized-PDMAEMA brushes (Q-PDMAEMA). The reversible solubilitiesof PDMAEMA- and Q-PDMAEMA-modified CNTs were achieved by switching between dif-ferent solutions. Palladium nanoparticles were attached onto the CNTs using Q-PDMAEMAmediated anion exchange followed by in situ reduction using NaBH4. The electrocatalyticbehavior of the material was studied using an electrochemical method. |
