Graphene oxide-loaded shortening (GOS), an environmentally friendly heat transfer fluid with high thermal conductivity, was successfully prepared by mixing graphene oxide (GO) with a shortening. Scanning electron microscopy revealed that GO particles, prepared by the modified Hummer?s method, dispersed well in the shortening. In addition, the latent heat of GOS decreased while their viscosity and thermal conductivity increased with increasing the amount of loaded GO. The thermal conductivity of the GOS with 4% GO was higher than that of pure shortening of ca. three times, from 0.1751 to 0.6022 W/mK, and increased with increasing temperature. The GOS started to be degraded at ca. 360?C. After being heated and cooled at 100?C for 100 cycles, its viscosity slightly decreased and no chemical degradation was observed. Therefore, the prepared GOS is potentially used as environmentally friendly heat transfer fluid at high temperature.

Key Factor

Graphene is often used to improve the thermal conductivity of polymers but usually with high amount. The key factor that limits the thermal conductivity is graphene agglomeration as well as the incompatible interface between graphene and polymer. Here, we report super-high thermal conductivity of polyamide-6 (PA6) composites achieved by adding small amounts of graphene oxide (GO)-stabilized graphene dispersions (graphene-GO). The introduction of GO not only acts as an effective dispersant for graphene due to the non-covalent π-stacking interactions but also participates in PA6 polymerization. Therefore, the issues associated with graphene dispersion in PA6 can be resolved and the interface adhesion enhanced by adding small amounts of graphene-GO. Furthermore, this approach reduces the tendency for decreased crystallinity. All these factors enhance the formation of heat conducting pathways among the graphene sheets. Thus, compared with graphene, graphene-GO enhances thermal conductivity at lower filler loading levels by enhancing graphene dispersion and interface adhesion.
