Thermal transport in silver-coated polymer sphere composites by the bidirectional 3 ω method

The bidirectional 3 ω method is an electrothermal technique that is commonly used to obtain the thermal conductivity of materials such as liquids, biological samples, and pastes. In this work, an epoxy-based adhesive was filled with monodisperse 10 μm polymethyl methacrylate spheres coated with silv...

In this work, an epoxy-based adhesive was filled with monodisperse 10 μm polymethyl methacrylate spheres coated with silver thin films (AgPS), such that a metallic network that dominated the thermal transport was formed through the composite. The bidirectional 3 ω method was used to obtain the thermal conductivity of the conductive adhesive at different volume fractions of AgPS. For 50 vol.% AgPS, corresponding to 3.4 vol.% silver, the thermal conductivity was 2.03 ± 0.21 W m-1 K-1. The results show that the thermal conductivity is strongly correlated with the AgPS volume fraction, while maintaining a volume fraction of silver far below the commercial silver paste, which has typical filler fractions of 40 vol.% silver. The results of this work were compared to thermal measurements of the same material by other techniques, and advantages and disadvantages of the methods were finally discussed.The NTNU authors wish to acknowledge the Research Council of Norway for the support to this project through the FRINATEK Project No. 251068 with the title “Engineering Metal-Polymer Interface for Enhanced Heat Transfer (HEFACE)” and also for supporting the NTNU NanoLab through the Norwegian Micro- and Nano-Fabrication Facility, NorFab, Project No. 245963.

The bidirectional 3 ω method was used to obtain the thermal conductivity of the conductive adhesive at different volume fractions of AgPS. For 50 vol.% AgPS, corresponding to 3.4 vol.% silver, the thermal conductivity was 2.03 ± 0.21 W m-1 K-1.
