Morphology and Thermal Stability of Various Types of Carbon Nanoparticles for Conductive Ink Applications.

In recent years, carbon fillers have attracted a great deal of attention due to their superior electrical properties. In this study, graphene foam (GF) has been successfully synthesized by using solvothermal reaction method. Carbon fillers such as graphene nanoplatelets (GNP) and synthetic graphite (SG) were also used for comparison. The scanning electron micrographs showed that GF has porous 3D structure, meanwhile for GNP and SG have flaky and irregular shape. However, GF has low thermal stability as compared to those of GNP and SG. [ABSTRACT FROM AUTHOR]
