GO-HNT framework-based hydrogels with efficient water evaporation-driven cooling and superior electromagnetic wave absorption.

Heat dissipation and electromagnetic wave absorption (EWA) are crucial for mitigating heat accumulation and electromagnetic interference issues in electronics. Conventionally, incorporation of specific fillers to polymer substrates is widely adopted to address these issues, although it is often challenging to simultaneously realize high thermal conductivity and effective EWA performance this approach. In this work, graphene oxide/halloysite nanotube (GH) frameworks were incorporated into hydrogels.

High-Performance Thermoelectric Composite of BiTe Nanosheets and Carbon Aerogel for Harvesting of Environmental Electromagnetic Energy.

Intensifying the severity of electromagnetic (EM) pollution in the environment represents a significant threat to human health and results in considerable energy wastage. Here, we provide a strategy for electricity generation from heat generated by electromagnetic wave radiation captured from the surrounding environment that can reduce the level of electromagnetic pollution while alleviating the energy crisis. We prepared a porous, elastomeric, and lightweight BiTe/carbon aerogel (CN@BiTe) by a simple strategy of induced in situ growth of BiTe nanosheets with three-dimensional (3D) carbon structure, realizing the coupling of electromagnetic wave absorption (EMA) and thermoelectric (TE) properties.

Advanced multifunctional IGBT packing materials with enhanced thermal conductivity and electromagnetic wave absorption properties.

Insulated-Gate Bipolar Transistors (IGBT) face limitations in high-frequency electronic applications due to heat accumulation and electromagnetic interference issues. To address these challenges, it is crucial to develop packing materials with excellent electromagnetic interference immunity and heat dissipation properties. In this research, a novel epoxy-based packing material (MDCF@C-ZrO/EP) with high electromagnetic wave absorption and exceptional thermal transport properties was produced by employing a unique three-dimensional carbon structure-induced nanomaterial dispersion strategy.
