Investigation of morphology and composition of Laser Induced Graphene from polymer precursors
Hana Hampel
11:15 - 12:15 Wednesday 11 March 2020 PH 01 150 Laser Induced Graphene (LIG) is a porous and conductive carbon material produced by laser-induced pyrolysis of various polymer substrates. An infrared laser, as typically used in commercial CO2 laser cutter in manufacturing, is used for this purpose.
The main goal of this thesis is to get a better understanding of the laser-induced synthesis, the boundary conditions for the formation of LIG and the tuning of its morphology and properties. Until now polyimide was used as a precursor for the LIG production. Due to the increasing environmental concerns and in view of expanding the field of applications, a second objective is to investigate alternative polymer precursors. A preliminary investigation into the development of some biologically derived and biodegradable polymer precursors was made.
