Polydopamine-coated boron nitride nanofiller

8% higher breakdown strength

Uniformly dispersed polydopamine-modified boron nitride nanoparticles in epoxy effectively suppress charge migration at 1 wt% loading, achieving both a deeper trap energy level and higher DC breakdown strength compared to unmodified filler composites.
