Expanded ultraporous graphite electrodes for (bio)electronics devices
Fabrication d'électrodes en graphite pop-corn pour l'électronique et la bioélectronique
Résumé
The present disclosure provides the fabrication procedure of expanded graphite materials derived conductive papers for usage as cost-friendly scalable bioelectrodes. The resulting macroporous electrode structures provide favourable pore architecture, including larger porosity and hierarchical porosity, for enhanced (bio)electrocatalysis. The pore architecture enables improved immobilization, and sufficient electrical contact between the compounds for smooth transfer of ions and compounds. The presence of a fluffy paper structure at the end product increase the volume thereby facilitating higher enzyme loading and thus giving rise to high volumetric charge storage properties.
