Abstract
The present disclosure relates to a patternable process for coating functional and adherent graphene-like carbon on multiple substrate types using CO2 laser-induced photothermal pyrolysis in scanning mode. The poly furfuryl alcohol (PFA) synthesised via low-temperature polymerisation of furfuryl alcohol precursor without any additives was used to form graphene-like carbon material.
