Applications of Graphene Thermal Management Materials
Overview
With technological advancements and increased consumer capacity, electronic products like smartphones, tablets, and computers have become indispensable in daily life. The commercialization of 5G technology heralds a future where human-machine interaction is a mainstream application, leading to more frequent smartphone usage. However, prolonged use can cause phones to overheat, posing a challenge for manufacturers. Graphene offers an effective solution to this issue.
Importance of Heat Dissipation in Electronics
Heat dissipation in electronic products affects power consumption and lifespan. Poor thermal performance can impact product functionality, miniaturization, and safety perceptions. Traditionally, smartphones have used large metal backplates and temperature regulation measures for heat management, which conflicts with the consumer desire for lighter and higher-performing devices. Thus, new materials are needed to address heat dissipation in electronics.
Advantages of Graphene in Thermal Management
Graphene’s high elastic modulus, mean free path, and thermal conductivity make it a promising new material for electronic manufacturers. Its stability in high-temperature environments allows for efficient heat dissipation, meeting the thermal management requirements of electronic products. Graphene’s thermal capacity is approximately four times that of conventional aluminum alloys. Major smartphone manufacturers have introduced flagship phones with graphene-based cooling solutions, receiving positive user feedback.
Current Applications and Future Prospects
Graphene thermal management materials are now part of strategic emerging industry projects, widely used in smartphones, tablets, and other consumer electronics. They also hold potential for many other fields, underscoring their high practicality. As technology advances, new solutions for thermal management in electronics are expected to emerge.
