What Are the Factors Influencing Thermal Instability?
Several factors influence the thermal instability of nanomaterials:
Material composition: Different materials have varying thermal stabilities. For instance, metals may oxidize, whereas polymers may decompose at elevated temperatures. Size and shape: The thermal behavior of nanomaterials can vary significantly with changes in size and shape, affecting their stability. Surface chemistry: The presence of surface ligands or coatings can influence the thermal stability by either protecting the material or introducing additional instability. Environmental conditions: The surrounding atmosphere (e.g., presence of oxygen or humidity) can play a crucial role in the thermal stability of nanomaterials.
