The present work deals with the measurement of thermo-physical properties of a
freestanding sheet of graphene (thermal diffusivity and thermal conductivity), and their
dependence on sample density as result of uniform mechanical compression. Thermal
diffusivity of graphene nano-platelets (thin slabs) was measured by the pulse flash method.
Obtained response data were processed with a specifically developed least square data
processing algorithm. GNP specific heat was assumed from literature and thermal …
