Thermal cycling impacts nanomaterials in several ways:
Structural Changes: Repeated heating and cooling can cause expansion and contraction in the material, leading to microcracks or even fracture at the nanoscale. Phase Transitions: Some nanomaterials may undergo phase transitions due to thermal cycling, affecting their material properties. Stress Accumulation: Differential thermal expansion between different parts of a nanomaterial can lead to stress accumulation, impacting its mechanical integrity. Oxidation and Corrosion: Thermal cycling can accelerate the oxidation and corrosion of nanomaterials, particularly in metal nanoparticles.
