It is found that breaking the polymerization backbone bond induces effective removal of poly(methyl methacrylate) on the graphene surface by depolymerization, and decomposition of the carboxyl functional group involves reducing the level of p-doping of the graphene, while the annealing process leads to an increase in defects, and consequently, to oxidation that transforms the graphene into p-doped material.
