This work explains the functionalization of polyallylamine (PAA) on the graphene oxide (GO) sheets following a chemical route. The resulting GO-PAA complex is characterized by using various imaging and analytical tools. In the Raman spectroscopy for both the GO and GO-PAA, the appearance of D and G characteristic bands correspond to the sp 2 and sp 3 contents, respectively, in the carbon sheets. The observation of lowered D/G peak intensity ratio of these peaks from 1.3 for GO to 1.1 for GO-PAAdoi:10.5185/amp.2016/3015 fatcat:npauzqzqsraw3aozlru4ec67hq
