Chemical Composition: The intrinsic properties of the elements or compounds that make up the nanomaterial can affect its resistance to chemical and physical degradation. Size and Shape: Smaller particles or certain shapes might have higher reactivity, influencing their stability and durability. Surface Area: A higher surface area to volume ratio can lead to increased reactivity and potential degradation. Environmental Conditions: Exposure to factors such as temperature, humidity, and radiation can significantly impact the durability of nanomaterials.
