ABSTRACT

Graphene or few-layer graphene (FLG) has been proposed as a material for making advanced electronic devices. The incompatibility between PDMS and the mechanical properties of graphene usually causes breaks during the fabrication process, especially during the etching step Thermal tape (T-tape) from Nitto Denko Inc. was used to transfer the multilayer grid patterned graphene onto glass coverslips. T-tape was used to peel off thick multilayer graphene flakes, which contained the transmission electron microscopy (TEM) grid pattern. Nickel TEM grids were used as physical masks for the oxygen plasma lithography. The ~100 nm wide graphite nanowire was printed onto Polydimethylsiloxane (PDMS) using soft lithography. The chapter explores a method for printing graphene nanowires onto PDMS substrates without using any wet chemical processing. The potential for simplicity, speed, and reproducibility anticipated for lithographic patterning via contact printing on a transparent, biocompatible, and flexible surface makes this combination of methods and materials a strong candidate for nanofabrication of platforms supporting sensing nanoarchitectures.
