Direct transfer of graphene onto flexible substrates | …

We investigated a lamination technique for directly transferring graphene onto various flexible substrates, which does not require using polymethylmethacrylate (PMMA) as an intermediate transfer membrane. Our studies reveal that the method is most effective on hydrophobic substrates with low glass transition temperature. For substrates like paper or cloth that do not meet these criteria, a ...
