In this chapter we consider three examples of thermal methods: thermogravimetry, differential thermal analysis, and differential scanning calorimetry.

Under oxygen, SWNTs will pyrolyze leaving any inorganic residue behind. Differential scanning calorimetry (DSC) is a technique used to measure the difference in the heat flow rate of a sample and a reference over a controlled temperature range.

While the reference chamber contains only a solvent, the sample chamber contains an equal amount of the same solvent in addition to the substance of interest, of which the ΔH is being determined. The ΔH due to the solvent is constant in both chambers, so any difference can be attributed to the presence of the substance of interest.

In DTA the temperature applied to the sample is increased linearly and the difference between the temperature of the reference material and the temperature of the sample is recorded as function of the sample's temperature

At the glass transition temperature, the physical nature of the material changes subtly. It goes from being a rubbery, flexible material at higher temperature, above the glass transition, to a glassy, harder material at a lower temperature. The material is still a solid either way, but there is a definite change in how it responds to stimuli.
