Comparison of carbon nanofiller-based polymer composite adhesives and pastes for thermal interface applications

摘要: Abstract Graphite nanoplatelets (GNP), carbon black (CB) and nanotubes are extensively researched to produce thermal interface materials (TIMs). This work reports comparison of interfacial conductance (ITC) nanofiller-based polymer composite adhesives pastes. The results show that total contact resistance (TTCR) GNP/rubbery epoxy was the same as an equivalent glassy composite. Although CB-based rubbery silicone composites can be applied thin bondlines, their TTCRs were significantly higher than epoxy. GNP incorporation into CB/rubbery improves ITC but performance CB/GNP/rubbery inferior paste GNP/polyetheramine had TTCR 4.8 × 10− 6 m2·K/W which is comparable commercial TIM-paste. produced with relatively poor versus prepared polyetheramine. having smaller particle sized GNPs offers lower large GNPs. from precursor pastes gave lowest in other adhesives. study suggests offer potential for enhancing TIMs depends on fillers' conductivity substrates.
