For bulk polymers, both the coefficient of thermal expansion and the modulus have been measured as mentioned above.A more sensitive procedure has been developed for thin film analysis called local thermal analysis (LTA). In this technique the probe itself is heated and is therefore able to measure the expansion and transitions of thin films more accurately.
