Shoulf read function of graphite

Graphite can be used as a filler for increasing the thermal conductvity of sugar foams by more than one order of magnitude, see attached files. It doesn't really behave as reinforcement since the mechanical strength is not improved but rather decreased instead. As graphite somewhat prevents foaming due to the higher viscosity of the melt, it tends to decrease the porosity of the final sucrose foams. Therefore finding a foam presenting both high porosoty and high thermal conductivity is a question of compromise. The same should certainly apply to electrical conductivity.
