Production of laser-induced graphene using ns- andps- laser sources

Póster.--European Materials Research Society Spring Meeting, Laser material processing: from fundamental interactions to innovative applications, May 31- June 3, 2021Laser-direct writing of graphene structures on different polymeric sources has been demonstrated to be a potential approach to produce, among others, micro-supercapacitors, nano-generators or sensors. Laser-induced graphene is produced on the surface of polymers by using, in general, laser radiation emitted by CO2 lasers due to the good absorption of most polymers to this laser radiation. The fast thermal decomposition and carbonization of the laser irradiated surfaces lead to the formation of graphene. In this work, we have studied the capabilities of other laser sources emitting ns- or ps- pulses to produce graphene on some polymers. These are able to produce graphene patterns with a higher resolution, and finer details can be produced. Finally, we demonstrate the capability of this graphene to be used as temperature sensorsN
