Biodegradable Printable Insulating Dielectric for Multilayer Rigid and Flex Printed Circuit Board (PCB) Board Manufacturing

here exists a need for insulating printable dielectric to also be biodegradable to make the PCB be truly sustainable. There has been much research work done in recent years for printable Biodegradable Cellulose materials has been used for 3D applications using standard 3D printing methods from extrusion to photopolymerization . There has been work done in cellulose as a filler in a 3D printing of sensors, but there is not a commercially viable method yet for sustainable printed electronics. Developing a Biodegradable printable material that can meet the mechanical and electrical requirements of most sectors within the electronics industry would be a game changer.
