Graphene/Poly(aniline-co-diphenylamine) nanohybrid for ultrasensitive electrochemical glucose sensor

In this work, a copolymer (polyaniline(PANI)-copolymer(co)-polydiphenylamine (PDPA)) hybrid impregnated on graphene (Gra) nanosheets was examined. At first, graphene was synthesized by the oxidation of natural graphite employing modified Hummer’s method and subsequently reduced using hydrazine monohydrate. Then, interfacial chemical oxidative polymerization was engaged to synthesize PANI, PDPA, and copolymer (PANI/PDPA) along with graphene...
