This graphical abstract illustrates the structure of hexagonal boron nitride (h-BN) and hydroxylation of h-BN. The pristine h-BN exhibit a hexagonal lattice structure with alternating boron (B) and nitrogen (N) atoms. Upon hydroxylation, hydroxyl (-OH) groups are introduced at the edges and surfaces of the BN nanosheets, enhancing their reactivity and dispersibility. The hydroxylated BN nanosheets show improved interfacial interactions, which can lead to better thermal and mechanical properties in composite materials.

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.
