I will discuss our recent progress at the University of Maryland, about engineering of 2D materials, with a focus on metal ion intercalation and ultra-high temperature treatment. We developed a nano-battery platform that allows in situ measurement of optical, electrical and structure changes of 2D materials during ion intercalations. We used the nano-battery setup to investigate various properties of 2D materials upon ion intercalation, including Li+, Na+ and K+. Dramatic increases in both transmittance and conductivity were reported, which leads to the highest figure of merit (FOM) for transparent conductor applications. We also extended the knowledge to printed reduced graphene oxide network toward large-scale applications. In a separated topic, I will discuss our effort in the past two years on high temperature material behavior for reduced graphene oxide (RGO) networks, which can generate an ultra-high temperature up to 3000-3500K.
