Thermal mechanical analysis data showing thermal expansion of panel 1 (black), panel 4 (brown), panel 7 (blue), and panel 9 (green). Lower thermal expansion value of panel 7 is attributed to greater expansion in the in-plane direction as opposed to the out-of-plane direction that is measured. When CNT concentration is low composite expansion is similar to control as seen by panel 7 data points (−). Higher thermal expansion is ascribed to greater bond dissociation.
