The rapid advancement of fifth-generation (5G) communication and high-power electronic devices has revolutionized modern life, yet it also brings about dual challenges of electromagnetic wave (EMW) pollution and heat accumulation, which severely threaten the stability and service life of integrated components. While hexagonal boron nitride (h-BN) is a promising candidate for thermal management due to its high thermal conductivity and chemical stability, its inherent electrical insulation and chemical inertness significantly limit its ability to absorb EMWs. Achieving simultaneous high-efficiency EMW absorption and thermal conductivity in a single BN-based composite remains a significant challenge, as traditional modification methods often involve complex processes or harsh chemicals.
