One-pot polymer modification of carbon nanotubes through mercaptoacetic acid locking imine reaction and pi-pi stacking

摘要

By 'grafting to' strategy, polymers (poly(ethylene glycol), poly(methyl methacrylate)) have been facilely linked on carbon nanotube (CNT) surface through simultaneous pi-pi stacking and mercaptoacetic acid locking imine (MALI) reaction to achieve the CNT-polymer complex. The targeted polymers could be effectively anchored on CNT surface under mild condition (room temperature, catalyst free), and the therefore obtained CNT-polymer complex can be well dispersed in regular used organic or aqueous solvents, suggesting this simple method an efficient approach to prepare CNT-polymer nanocomposite.
