Thermally conductive and electrically insulating thermal interface materials (TIMs) are highly desired for electronic cooling. To improve heat transfer efficiency, thermally fillers with a high loading content have been incorporated into the polymer-based TIMs. However, this is usually at expense of interfacial resistance reduction reliability. In study, vertically aligned boron nitride nanosheet films (VBNFs) prepared by scalable microfluidic spinning process template-assisted chemical vapor deposition conversion method.

Abstract Two-dimensional materials with ultrahigh in-plane thermal conductivity are ideal for heat spreader applications but cause significant contact resistance in complex interfaces, limiting their use as interface materials. In this study, we present an interfacial phonon bridge strategy to reduce the of boron nitride nanosheets-based composites. By using a low-molecular-weight polymer, able manipulate alignment nanosheets through sequential stacking and cutting, ultimately achieving flexible thin films layer arc-like structure superimposed on perpendicularly aligned ones. Our results suggest that can act lower by 70% reducing back-reflection enhancing coupling efficiency at boundary. The resulting composites exhibit ultralow 0.059 2 KW −1 , demonstrating effective cooling fast-charging batteries thickness 2-5 times thinner than commercial products.
