A Novel Graphene and Titanium Laminated Composite Film for Electronics Cooling Applications

With the pursuit of electronics product performance, the thermal management of electronics devices is becoming increasingly prominent. It is well-known that graphene film (GF) has very good heat dissipation properties, while metal materials have excellent mechanical properties and anti-aging properties. If they are prepared into laminated materials, which can be used as the shell of heat pipes, vapor chambers and other heat dissipation devices to improve heat dissipation capacity. In this study, we developed a set of new GF/metal laminates and fabricated a new type of lightweight and high thermal conductivity GF/Ti laminated material with an out-plane thermal conductivity of 8.64 Wm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup>K<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup>.
