Understanding the Thermal Impedance of silicone Rubber/hexagonal Boron Nitride Composites as Thermal Interface Materials

引用

Chinese Journal of Polymer science 2024年第3期42卷 352-363,I0008页

作者： Yuan Ji shi-Da han hong Wu shao-Yun Guo feng-shun Zhang Jian-hui Qiu The state Key Laboratory of Polymer Materials Engineering Sichuan Provincial Engineering Laboratory of Plastic/Rubber Complex Processing TechnologyPolymer Research InstituteSichuan UniversityChengdu 610065China Institute of Chemical Materials China Academy of Engineering PhysicsMianyang 621900China Department of Mechanical Engineering Faculty of Systems Science and TechnologyAkita Prefectural UniversityAkita 015-0055Japan

silicone rubber(sR) composites are most widely used as thermal interface materials(TIMs) for electronics.h.at dissipation. Thermal impedance as the main bottleneck limiting the performance of TIMs is usually neglected. herein, the thermal impedance of sR composites loaded with different levels of hexagonal boron nitride(h-BN) as TIMs was elaborated for the first time by the AsTM D 5470 standard test and finite element analysis. It was found that elastic modulus and surface roughness of sR composites increased with the increase of h-BN content, indicating that the conformity was reduced. When the assembly pressure was 0.69 MPa, there existed an optimal h-BN content at which the contact resistance was minimum(0.39 K·cm^(2)·W^(-1)). Although the decreased bond line thickness(BLT) by increasing the assembly pressure was beneficial to reduce the thermal impedance, the proper assembly pressure should be selected to prevent the warpage of the contact surfaces and the increase in contact resistance, according to the compression properties of the sR composites. This study provides valuable insights into fabrication of high-performance TIMs for modern electronic device applications.

Effect of Ball Milling Time on Microstructure and hydrogen storage Properties of Nd_(5)Mg_(41)Ni Alloy

引用

Acta Metallurgica sinica(English Letters) 2024年第7期37卷 1201-1214页

作者： Zeming Yuan Chenxu Liu Xiaoming Li Yongqi sui Zhonggang han Tingting Zhai Dianchen feng Yanghuan Zhang Instrumental Analysis Center Inner Mongolia University of Science and TechnologyBaotou014010China Department of Functional Material Research Central Iron and Steel Research InstituteBeijing100081China

Mg-based alloys must be dehydrogenated at high pressure and temperatures, limiting their practical application. In this paper, Nd_(5)Mg_(41)Ni alloy was prepared by vacuum melting, and the as-cast alloy was ball milled for 5 h, 10 h, 15 h, and 20 h. The effect of ball milling time on the microstructure and hydrogen storage properties of the alloy was systematically studied. The alloy comprises Nd_(5)Mg_(41), NdMg_(12), NdMg_(3), and Mg_(2)Ni phases. The Nd_(5)Mg_(41)Ni alloy milling for 10 h can reach 95% of the saturated hydrogen absorption at 553 K by 40 s, and the alloy can desorb hydrogen only by 20 min. The dehydrogenation activation energy is only 99.9 kJ/mol h_(2). Ball milling makes the alloy produce many nanocrystalline and amorphous structures. The nano-grain boundary provides a channel for the diffusion of hydrogen atoms, and the high energy at the grain boundary provides energy for the phase deformation nucleus. Ball milling leads to the refinement of alloy particles and shortens the diffusion distance of hydrogen atoms to the interior of alloy particles. Defects such as twins and dislocations generated by milling provide energy for the phase deformation nucleus during the hydrogen absorption and desorption.
