The increasing rate was diminished after a threshold temperature of 35 °C (MIX-1) and 40 °C (MIX-2). This behavior, being more severe in functionalized cases, can be explained in terms of destruction of functional groups at high temperatures, which presumably declines the CNT dispersion quality and causes instability.
