Promisingly, the composite with 30 vol% GNSs delivered a high in-plane TC of 458 W/mK and a low through-plane CTE of 6.2 ppm/K, corresponding to a 35% TC enhancement and a 64% CTE reduction compared to pure Cu, respectively. Taetz, Christoph Behnam, Ashkan 2013. Moon, Ho Jun 2013. and This study is important for designing an optimum multi-functional polymeric packaging material.

Yu, Jing and In the present study, reduced graphene oxide (RGO) was prepared and characterized with FTIR, XRD, Raman spectroscopy, TEM, and AFM analysis. Yu, Lan Lim, Yun-Soo Pao, Chun-Wei Composites of graphene and matrix materials are expected to be the most promising TIMs because of the remarkable thermal conductivity of graphene. Huang, Xing Copyright © 2020 Elsevier B.V. or its licensors or contributors. 2013. Cuniberti, G. Bolotin, Kirill I. The synergy of RGO/alumina at 6:4 was found to enhance the thermal, insulation and mechanical properties of epoxy. Schuhmann, Wolfgang The anisotropic thermal conductivity (TC) and coefficient of thermal expansion (CTE) of graphene/Cu composite is studied. 2013. Article Download PDF … The composites showed a reversed anisotropic behavior between TC and CTE as a function of graphene fraction. 2013. Zou, Xiaolong R. Aradhana, S. Mohanty, S.K. Li, Zuanyi Introducing alumina into the RGO surface effectively interrupted its attraction through the matrix. Zhang, Xiaoliang Herein, we review the thermal properties of graphene, including its specific heat and thermal conductivity (from diffusive to ballistic limits) and the influence of substrates, defects, and other atomic modifications. 2013. and Baranov, Alexander V Buehler, Markus J.

Vaz, Alfredo R Nanocomposites of epoxy with 3 and 5 wt% graphene nanoplatelets (GnPs) were fabricated with GnP sizes of ~5 and <1 μm dispersed within an epoxy resin using a sonication process followed by three-roll milling. Huang, Huaqing Kilzer, Andreas Champagne, A. R. 2013. High in-plane thermal conductivity is due to covalent sp2bonding between carbon atoms, whereas out-of-plane heat flow is limited by weak van der Waals coupling. Bashirzadeh, M. Min, K. Ong, Zhun-Yong and 2013. Accordingly, the thermal, electrical and mechanical properties of the hybrid epoxy nanocomposites were investigated to achieve the best performance. Pop, E. Graphene is a two-dimensional (2D) material with over 100-fold anisotropy of heat flow between the in-plane and out-of-plane directions. Pop, Eric Graphene (/ ˈ ɡ r æ f iː n /) is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice. Wang, Kang and Based on a decision-making technique, the synergy of RGO and alumina at 6:4 was considered to be the best. To date, electrically insulative alumina nanoparticles are chosen as a secondary filler to isolate the graphene sheets. Li, Ran While, the insulation properties of epoxy composites were retained significantly in contrast to RGO/epoxy composites. Pop, E. Konatham, Deepthi Ozkan, Cengiz S. Min, K. Handbook of Carbon, Graphite, Diamond and Fullerenes: Properties, Processing and Applications, Understanding Molecular Simulation: From Algorithms to Applications, Volume 37 Issue 12: graphene fundamentals and functionalities, Issue Gong, Jixuan Sevinçli, H. Ermakov, Victor A Because of the highly aligned GNSs and laminated structure, the GNS/Cu composites exhibited notably anisotropic thermal properties. First, the composition of graphene filled polymer composite TIMs is introduced. 2013. View all Google Scholar citations The highly aligned graphene was realized in graphene/Cu composite by vacuum filtration and spark plasma sintering. The present GNS/Cu composites with high in-plane TC and low through-plane CTE are promising candidates for specific thermal management applications that require an efficient in-plane heat dissipation but a good through-plane dimensional stability.

Pop, Eric Graphene oxide sheets with isocyanate functional groups (GO NCO) were firstly synthesized and functionalized graphene/polyimide (FGS/PI) nanocomposites were subsequently prepared by typical solution casting and thermal imidization. Jang, Chan Wook Bae, Myung-Ho For instance, graphene transistors and interconnects benefit from the high in-plane thermal conductivity, up to a certain channel length. 2013. This data will be updated every 24 hours. Li, Zuanyi Xiong, Feng However, weak thermal coupling with substrates implies that interfaces and contacts remain significant dissipation bottlenecks. and Wang, Hanxiong Bae, M.-H. Erbe, Andreas and Graphene holds great potential in metal matrix composites for thermal management due to its excellent thermal properties.
