The pesky poly(methyl methacrylate) (PMMA) residues left from transferring graphene grown by chemical vapour deposition (CVD) have remained a challenge for maximising this potentially scalable approach to high-quality graphene production. Now researchers at West Virginia University have demonstrated a simple electrolytic cleaning method for removing PMMA residues that greatly reduces impairments to the electronic properties caused by these contaminants………
