Thermal cycling effects and governing mechanisms of a CNT latex nanocomposite film
The thermal cycling effects as well as isothermal conditions on a conductive multi-walled carbon nanotube (MWCNT) filled latex film are presented and analyzed for a multi-day exposure period. Using a water-based latex solution, multi-walled CNT's have been doped within it and then applied with stencil masked spray deposition to the surface of a non-conductive manufactured substrate. Four-point probe resistivity measurements were conducted in-situ via electrodes deposited across the width of the latex film on the top surface via brush application. The temperature range of consideration was computer controlled using a nitrogen purged environmental chamber cycling between-50 to 80 °C with isothermal holds at each extrema. We have identified long term and short-term temperature-dependent resistivity trends as well as a correlation between environmental conditions and the effect on electrical properties of the nanocomposite.
