Abstract

Graphite films have excellent in-plane thermal conductivity but extremely low through-thickness thermal conductivity, due to the numerous interfaces. To improve the inter-layer heat transfer of graphite films, a simple interfacial modification with short duration mixed-acid treatment was developed. It was shown that the acid modification grafted small amounts of functional groups on graphite sheets and increased the through-thickness thermal conductivity by 27% and 42% for the graphite film and its composite, respectively, presenting a new simple way to modified graphite films.
