Graphene oxide solution preparation

Graphene can be prepared using four different methods [183]. The first is chemical vapor deposition (CVD) and epitaxial growth, such as the decomposition of ethylene on nickel surfaces. The second is the micromechanical exfoliation of graphite. The third method is epitaxial growth on electrically insulating surfaces, such as SiC, and the fourth is the solution-based reduction of graphene oxide (Fig. 31.17). 

Besides chemical approaches, electrochemical polymerization has also been used for the preparation of conducting polymer-carbon material nanocomposites. Zhou et al. [69] have used electrochemical co-deposition method to fabricate graphene oxide-PPy nanocomposites. Graphene oxide synthesized from natural graphene is dispersed in pyrrole solution and electrodeposited onto the FTO conducting glasses in a galvanostatic mode. Electrochemical deposition of PPy with...
