A Mini Review of Flexible Heat Spreaders Based on Functionalized Boron Nitride Nanosheets

Abstract This review provides a comprehensive overview of the recent progresses in flexible heat spreaders based on functionalized boron nitride nanosheets (f-BNNSs) and provides insights into the potential of this material for efficient thermal management solutions. The unique thermal properties of boron nitride nanosheets (BNNSs), such as high thermal conductivity and excellent mechanical flexibility, make them promising materials for heat dissipation. Various methods of functionalizing BNNSs to enhance their thermal and mechanical properties are discussed, including covalent functionalization and noncovalent functionalization. The numerous advanced methods to introduce f-BNNSs into polymers and the potential applications of the composites based on f-BNNSs in areas such as thermal management in electronic devices are also highlighted.
