Spatial functionalization of graphene powder using 1,4-dichlorobutane on ceramic substrate

Abstract The production of spatial structures on the ceramic substrates based on graphene powder cross-linked with 1,4-dichlorobutane under different parameters was studied. The influence of the type of environment, the concentration of the crosslinking compound and the time of crosslinking on the functionalization mechanism were determined. It has been shown that there is no significant effect of the solvent polarity on the attained degradation level (a measure of the degree of cross-linking of graphene flakes expressed as I D /I G parameter). Finally, the maximum defect volume was achieved with 120 h of functionalization, with a concentration of 90 mM, regardless of the environment in which the reactions took place. In this case the I D /I G parameter was close to 1.0, which contrasts the value obtained for pure powder where I D /I G was 0.77.
