Excess octadecane was removed from the emulsion using a separating funnel. The emulsion was then added to a mix of water-based matte black paint (Johnstone's) and graphite in a ratio of 90:8:2 (emulsion:paint:graphite) respectively in a 250 ml jar. The mixture was moderately stirred using a magnetic stir bar. The paint was analysed using DSC and TGA in the same method as previously stated and was also drop cast on an SEM stub for analysis.
