Nanobrick Wall Multilayer Thin Films with High Dielectric Breakdown Strength
Current thermally conductive and electrically insulating
insulation
systems are struggling to meet the needs of modern electronics due
to increasing heat generation and power densities. Little research
has focused on creating insulation systems that excel at both dissipating
heat and withstanding high voltages (i.e., have both high thermal
conductivity and a high breakdown strength). Herein, a polyelectrolyte-based
multilayer nanocomposite is demonstrated to be a thermally conductive
high-voltage insulation. Through inclusion of both boehmite and vermiculite
clay, the breakdown strength of the nanocomposite was increased by
≈115%. It was also found that this unique nanocomposite has
an increase in its breakdown strength, modulus, and hydrophobicity
when exposed to elevated temperatures. This readily scalable insulation
exhibits a remarkable combination of breakdown strength (250 kV/mm)
and thermal conductivity (0.16 W m–1 K–1) for a polyelectrolyte-based nanocomposite. This dual clay insulation
is a step toward meeting the needs of the next generation of high-performance
