제목 Functionalization of multi-walled carbon nanotubes in water through Diels-Alder cycloaddition under ultrasound-assistance
초록 A facile and environmentally friendly strategy for grafting polymers onto the surface of multi-walled carbon nanotubes (CNTs) was demonstrated by Diels-Alder click chemistry. Firstly, the copolymers of poly(maleic anhydride-co-N-isopropylacrylamide) (P(MA-co-NIPAm)) were prepared by the RAFT polymerization and subsequently functionalized with furfuryl amine as anchoring groups. The copolymers were then grafted on CNTs via the Diels-Alder reaction in water through a conventional heating-stirring route and ultrasound-assisted method. The obtained nanocomposite materials were characterized by GPC, FTIR, Raman spectroscopy, and TEM analysis. The results indicated that the reaction rate under ultrasound irradiation was accelerated much faster than the one under the conventional heating-stirring condition without losing the grafting efficiency. The direct functionalization of CNTs formed a stably dispersed solution in water, promising a green and effective method for industrial process.
