Dr. Xiaoqiang Li received his B.S degree in Materials Science and Engineering at Zhejiang University in 2005 and received his Ph.D degree in the year of 2010 in State Key Lab of Silicon Materials in Zhejiang University. Then Dr. Li worked in Hareon Solar and BP Solar, where he mainly worked on new type solar cell and thermal design of solar modules, for high efficiency and low temperature coefficient solar cells and modules. In the year 2012, Dr. Li Join in Hangzhou Gelanfeng Nanotechnology Co., Ltd as the general manager for grapheme technology development and industrialization. Based on his background, Dr. Li have done much work on graphene solar cell and graphene thermal dissipating products. Now Hangzhou Gelanfeng Nanotechnology Co., Ltd was honored as the the “Science and Technology Enterprise” in Zhejiang Province and “High and New Tech Enterprises” in Hangzhou. The related projects were supported by Hangzhou High Technology Zone (HHTZ) government.

内容摘要

Due to rapidly increasing power densities in electronics and optoelectronics, heat dissipation management has become one of the most critical issues in semiconductor devices and products design. Thermal interface materials are essential ingredients of thermal management, which are applied between the heat source and heat sinks. One of the most important properties for thermal interface materials is thermal conductivity. After been discovered in 2004, graphene had been found to have extreme high intrinsic thermal conductivity. Thus many researchers have done much work on graphene based thermal interface materials. In this report, we use modified multi-layer graphene to form paper-type thermal interface material with greatly enhanced thermal conductivity. This graphene-based thermal interface material was used in COB type LEDs’ thermal management design, temperatures of the LEDs with graphene were about 15ºC lower than that of ones with commercial silicone grease.
