Abstract Scope High surface area nanocarbons have repeatedly been shown to be promising for electrochemical sensors and supercapacitors. However, direct fabrication of highly conductive carbon electrodes with tunable porosity on flexible substrates is still challenging. In contrast to either traditional microfabrication techniques (which require transfer from rigid to flexible substrates) or printing approaches (which require post processing to improve the conductivity of as-printed nanocarbons from ink), we focus on bottom-up growth of graphene directly on polymer films by laser-induced localized heating. Here, we show the effect of process kinetics on the atomic structure, nanoscale morphology, and electrical conductivity of this laser-induced graphene. We also show that low resistivity of 0.04 cm can be achieved by multiple laser passes at different speeds. Moreover, we demonstrate that porosity can be tailored depending on the combination of laser parameters with the unique ability to achieve both low resistivity and high porosity.
