High-Performance Ink-Jet Printed Graphene Resistors Formed With Environmentally-Friendly Surfactant-Free Inks For Extreme Thermal Environments

Jan 11, 2018 | Monica Michel, Chandan Biswas, Anupama B. Kaul

Ink-jet printing is poised to impact the manufacturing of devices that are particularly attractive for flexible electronics, as more suitable and printable fluids become available. The addition of surfacants in the preparation of the inks usually results in additional process steps, potentially increasing cost, as well as material waste, where the surfactants also often have a negative impact on specific properties of the printed features, such as comprising electrical conductivity of metallic structures. (...)

In this work, we have successfully formulated a suitable ink derived from a mixture of terpineolin cyclohexanone as a more environmentally friendly option for the exfoliation of bulk graphite, which we elaborate upon in more detail here....
