Printing processes may make the electronics industry more sustainable and flexible by avoiding wasteful processes like chemical etching and enabling efficient roll-to-roll manufacturing. Traditionally, printed conductors are composed of metals. However, metals are sensitive to electromigration, and while copper is toxic and erosion-sensitive, gold and silver are expensive. Graphene, a carbon allotrope, is also conductive, and proposes an abundant, nontoxic, and affordable alternative to metals in functional inks for printed conductors. To enable the commercialization of printed graphene conductors, sustainable and nontoxic graphene-based ink formulations with high printability and scalable production potential are desired. In our work, we develop graphene dispersions for printed conductors and aim to understand and control their colloidal properties.
Laura van Hazendonk received a Double BSc Degree (cum laude) in Liberal Arts and Sciences from Maastricht University (the Netherlands) and the Albert-Ludwigs-University Freiburg (Germany), where she enjoyed a broad curriculum with a focus on Biochemistry and Bioinformatics. During her bachelors, she got the opportunity to study at the University of California, Los Angeles for an exchange quartile. After her bachelors, she transfered to Eindhoven University of Technology for a MSc in Materials Chemistry, where she graduated cum laude in 2020. During her masters, she worked as a research assistant in image analysis with Dr. Heiner Friedrich in the Laboratory of Materials and Interface Chemistry. She also joined the iGEM Eindhoven 2018 student team. With this team, she designed a living biomaterial for wound healing applications, which was rewarded with a gold medal in the international Genetically Engineered Machine competition. For her graduation research, Laura developed a systems approach for the study of collagen type I self-assembly under the supervision of Dr. Heiner Friedrich and Prof. dr. Remco Tuinier in the Laboratory of Physical Chemistry. Her thesis Engineering multiscale collagen scaffolds was awarded the AkzoNobel Graduation Award for Chemistry and Process Technology. After an internship at Corbion, she started as a PhD candidate in June 2020 in the Laboratory of Physical Chemistry, where she is continuing the collaboration with Dr. Heiner Friedrich and Prof. dr. Remco Tuinier.
