Purpose and goal
The project aims to study the possibility to use the excellent properties of graphene on heat spreader and/or connector in radar and laser devices. The graphene films have been synthesized, characterized in lab level and a preliminary reliability test was also performed. The outstanding mechanical properties, especially its flexibility makes the material to be a suitable candidate for heat connector application. Furthermore, the process of preparing graphene film still needs more precise control.
Expected results and effects
Since the requirements for heat spreader and heat connector are somehow different, that means we need to have more rigid material for heat spreader and more flexible one for heat connector. For heat connector, we have obtained the samples and it is ready for further testing in a simple -prototype set up. For heat spreading application, more effort needs to put to improve the graphene film’s functionality to reach the requirements. In a short, we see the possibility that graphene films could be applied both for heat spreading and connector applications.
Planned approach and implementation
The pre-study provides the opportunity to have a concept prove on potential application of heat transport by using graphene-based material. We also find suitable partners to form a cooperated consortium. We are planning to continue working in this area with more technical control, and closer collaboration between the material supplier and end user. We want to improve the process of graphene film with repeatable quality, quantity and could be tailored for specific applications. It is supposed the material could be into the market in 3-4 years.
