Alkynyl-functionalized graphene oxide (A-GO) is an integral a part of the clicking chemistry of graphene. Nevertheless, this type of functionalization usually happens in natural solvent system. On this research, a easy technique was used to organize alkynyl-functionalized graphene oxide below delicate and environmental-friendly circumstances. The outcomes confirmed that graphene oxide was efficiently modified by propargylamine. When the mass ratio of graphene oxide to propargylamine is 1:4, the very best grafting charge is 4.91%. The ensuing pattern turned rougher in microscopic morphology, however nonetheless had a lamellar construction. As well as, it may be obtained from XPS that along with the ring-opening response between the epoxy group and the amino group, there may be additionally the interplay between the carboxyl group and alkynyl ammonium. The current work supplies a facile and environmental-friendly technique towards alkynyl-functionalized graphene oxide.
