High-performance thermal interface material research progresses

Interaction between BN Nanotubes and Cellulose Nanofibers

Recently, the Advanced Electronic Packaging Materials Innovation Research Team led by Wang Zhengping and Sun Rong of the Chinese Academy of Sciences Shenzhen Institute of Advanced Technology and Xu Jianbin of the Chinese University of Hong Kong have made new breakthroughs in high-performance thermal interface materials.

With the rapid development of electronic technology, the power and integration of electronic devices has been increasing. Since 1959, the feature size of devices has been continuously reduced. It has evolved from the micron to the nanoscale, and the degree of integration is 40 to 50% every year. The high speed increases. In electronic devices, a considerable part of the power loss is converted into heat, and the dissipation of heat from the electronic device directly leads to an increase in the temperature of the electronic device and an increase in thermal stress, causing serious damage to the reliability and service life of the electronic device. Threats, research and development of high-performance thermal interface materials have received widespread attention from the scientific community and industry.

In view of the poor thermal conductivity of traditional polymer-based thermal interface materials, the thermal conductive substrate materials research group Xu Jianbin, Zeng Xiaoliang et al., designed the structure and preparation method of composite materials, combined the advantages of boron nitride nano and nano cellulose fibers, A highly oriented green degradable composite material was prepared using a simple vacuum-assisted suction filtration method. Due to the strong van der Waals interaction between the boron nitride nanotubes and the nanocellulose fibers, the green degradable composite has a thermal conductivity of 21.39 W/mK at a 25% mass fraction of boron nitride nanotubes. The research results provide a new green material and method for the preparation of high-performance thermal interface, which has a good application prospect.

The study was funded by Guangdong Province's "Advanced Electronic Packaging Materials" innovative research team, Shenzhen "Advanced Electronic Packaging Materials" peacock team, and National Natural Science Fund.
