TY - JOUR AU - Laursen, Mathias Kirkholt PY - 2019/01/04 Y2 - 2024/03/28 TI - Chemical Fabrication and Characterization of Graphene for Water-Based Inks used in Screen-Printing JF - UCPH NanoScience - a student research journal JA - UCPH NS VL - 2 IS - 0 SE - Papers DO - UR - https://tidsskrift.dk/nanovidenskabKU/article/view/111780 SP - AB - <p>Graphene exhibits a range of interesting properties such as high optical transmittance, good thermal conductivity, high<br>Young’s modulus, and good electrical conductivity. Graphene can serve as a component in conductive applications and<br>potentially replace the expensive conductive materials, such as indium tin oxide (ITO), that are used today. In this article<br>the graphene derivatives graphene oxide (GO) and reduced graphene oxide (rGO) are synthesized. The reduction of GO<br>is done by either microwave assisted reduction, intense light reduction or chemical reduction with hydrogen iodide. The<br>structures of the synthesized compounds are characterized and analyzed using X-ray photoelectron spectroscopy (XPS)<br>and Raman spectroscopy. Based on the synthesized GO, a GO-ink is formulated and screen-printed on a polymer-based<br>polyethylene terephthalate (PET) substrate, from which a sheet resistance of 0.4 kΩ s−q1 is measured. This work<br>suggests that the synthesized GO can be used in production of conductive circuits or serve as a precursor for future<br>scalable conductive films.</p> ER -
