  • Conductive Behaviour Of Graphene/Carbon Nanotube Hybrid Technique

    Part One: Conductive behaviour of graphene/carbon nanotube and graphene oxide/ carbon nanotube hybrid materials Experimental Introduction Although many CNTs and graphene based electrodes have been developed with outstanding properties, drawbacks are still noticeable using some methods. For instance, EPD method commonly produces unsatisfied CNTs film strength and on the other hand, CVD technique is costly. Moreover, graphene based electrodes needs lots of labour works which is time consuming…
