How Does Poor Thermal Conductivity Impact Applications?
Poor thermal conductivity in nanomaterials can have both advantageous and detrimental effects, depending on the application:
Electronics: In electronic devices, poor thermal conductivity can lead to overheating, reducing device efficiency and lifespan. However, in certain cases, it can also be used to create thermal barriers, protecting sensitive components from heat. Thermoelectric Materials: For thermoelectric applications, low thermal conductivity is desirable as it enhances the figure of merit (ZT) by maintaining a high temperature gradient. Nanostructuring is often utilized to achieve this. Energy Storage: In energy storage systems, such as batteries, poor thermal conductivity can affect the temperature distribution during charging and discharging, influencing performance and safety. Nanocomposites: In nanocomposites, the thermal properties of the filler materials can significantly impact the overall thermal conductivity of the composite. Tailoring the interfacial properties can help manage heat transfer.
