Abstract

Abstract With the rapid development of 5G information technology, thermal conductivity/dissipation problems of highly integrated electronic devices and electrical equipment are becoming prominent. In this work, “high-temperature solid-phase & diazonium salt decomposition” method is carried out to prepare benzidine-functionalized boron nitride ( m -BN). Subsequently, m -BN/poly( p -phenylene benzobisoxazole) nanofiber (PNF) nanocomposite paper with nacre-mimetic layered structures is prepared via sol–gel film transformation approach. The obtained m -BN/PNF nanocomposite paper with 50 wt% m -BN presents excellent thermal conductivity, incredible electrical insulation, outstanding mechanical properties and…
