Thermal properties of compressed expanded graphite: photothermal measurements [PDF]
Applied Physics B, 2011 The thermal diffusivity and the thermal conductivity of compressed expanded graphite (CEG) samples were investigated by photothermal measurements in two geometries differing by a place of temperature disturbance detection. This disturbance can be detected on a surface opposite to the one at which the disturbance was generated (rear detection) or on the

Flame retardant and thermal behavior of polylactide/expandable graphite composites
Polimery, 2013 In this article expandable graphitewas used to produce fire retardant biobased poly- lactide. For this purpose,PLAblends with addition of 1, 5 or 10 wt.%of expandable graphite inter- calated with sulphuric acid (GR) were obtained using co-rotating twin screw extruder.
