“…The treatment can generate some other defects in HO-BNs. If the temperature reaches 1500°C, the products have to be hydroxylated by the above methods [47][48][49][50][51][52][53] h-BNNSs Sonication-assisted exfoliation It is a facile method to directly exfoliate BN bulk into HO-BNNSs The hydroxyl degree is relatively low For a high hydroxyl degree, some additives have to be introduced, such as, acid, base, salt, etc [31,[55][56][57][58][59][60][61][62][63] Ball-milling-assisted exfoliation Situations similar to ''sonication-assisted exfoliation'' [64][65][66][67][68][69][70][71][72] Hummer's-like routes The use of strong oxidants (i.e., H 2 SO 4 , H 2 O 2 , KMnO 4 , and their mixtures) requires an extra attention Sometimes the oxidization process can lead to the presence of a few by-products of BN dots [73][74][75][76] Multi-step functionalization method It can be divided into two stages: one is from BN to BNNS and then to HO-BNNS, the other is from BN to HO-BN and then to HO-BNNS [82][83][84][85][86][87][88][89][90][91][92] Bottom-up routes It generally requires high temp...…”

Functionalization of boron nitride (BN) materials with hydroxyls has attracted great attention to accomplish better performances at micro- and nanoscale. BN surface hydroxylation, in fact, induces a change in properties and allows expanding the fields of application. In this review, we have summarized the state-of-the-art in developing hydroxylated bulk and nanoscale BN materials. The different synthesis routes to develop hydroxyl BN have been critically discussed. What emerges is the great variety of possible strategies to achieve BN hydroxylation, which, in turn, represents one of the most suitable methods to improve the solubility of BN nanomaterials. The improved stability of BN solutions creates conditions for producing high-quality nanocomposites. Furthermore, new interesting optical and electronic properties may arise from the functionalization by OH groups as displayed by a wide range of both theoretical and experimental studies. After the presentation of the most significant systems and methodologies, we question of future perspective and important trends of the next generation BN materials as well as the possible areas of advanced research. Graphical abstract Hydroxyl functionalization of boron nitride materials is a key method to control and enhance the properties and design new functional applications.

“…8). Besides, as seen in the previous section, the introduction of some chemical agents, such as NaOH and KOH [64][65][66][67], NaClO [68], urea [69,70], H 3 BO 3 [71], and b-cyclodextrin [72], can lead to a synergetic effect of mechanical process and chemical peeling.…”

“…A recently more popular approach has been the use of mechanical forces, specifically by ball-milling either independently or coupled with the pre-or post-treatment with vigorous sonication in selected solvents, to impart exfoliation of h-BN. [33,53,[96][97][98][99][100][101][102][103][104][105][106][107][108] Typically, the samples for ball-milling are mixtures of h-BN with selected organic molecules or bases such as aqueous NaOH. [96][97][98] With molecules containing amine moieties mixed with h-BN, for example, the ball-milling of the mixtures in the solid state or as slurries is conceptually comparable with the use of similar amino molecules as dispersion-functionalization agents for h-BN in solution or suspension, [33,[99][100][101][102] except for the required energy delivered by the mechanical force in the former versus by sonication in the latter.…”

“…Beyond urea, other organic compounds have also been explored, often with the consideration of their surface tensions being similar to that of h-BN. [103][104][105][106][107][108] For example, Li, et al reported the use of wet ballmilling with benzyl benzoate, ethanol, and dodecane for gentle shear forces to cleave and peel h-BN. [103] Lee and coworkers used ball-milling in the presence of aqueous NaOH, followed by sonication, to prepare OH-modified BNNs.…”

Hexagonal boron nitride (h‐BN) and exfoliated nanosheets (BNNs) not only resemble their carbon counterparts graphite and graphene nanosheets in structural configurations and many excellent materials characteristics, especially the ultra‐high thermal conductivity, but also offer other unique properties such as being electrically insulating and extreme chemical stability and oxidation resistance even at elevated temperatures. In fact, BNNs as a special class of 2‐D nanomaterials have been widely pursued for technological applications that are beyond the reach of their carbon counterparts. Highlighted in this article are significant recent advances in the development of more effective and efficient exfoliation techniques for high‐quality BNNs, the understanding of their characteristic properties, and the use of BNNs in polymeric nanocomposites for thermally conductive yet electrically insulating materials and systems. Major challenges and opportunities for further advances in the relevant research field are also discussed.

With the rapid development of electronic devices toward the miniaturization, integration, and multi‐functionalization, the device stability, reliability, and service life face significant challenges due to the greatly increased heat accumulation. Therefore, it is highly desired to develop efficient thermal dissipation materials in thermal management. Thermally conductive polymer composites are expected to be widely applied in 5G communication, electronic packaging, and energy storage, owing to the ease of processing, good flexibility, low cost, etc. Boron nitride nanosheet (BNNS) is generally used as highly thermal conductive nanofillers for greatly improving the thermal conductivity of polymer. Mass production of high quality BNNS with desired properties and the structural design principles and fabrication methods for polymer/BNNS nanocomposites are critical to achieve extensive applications. Here, this review summarizes the latest advancement of the preparation method of BNNS and its polymer nanocomposites, as well as the innovatively structural design for observably improving the thermal management capability and energy storage performance of polymer/BNNS nanocomposites, expecting to offer some guidance on how to massively fabricate the BNNS and highly thermally conductive polymer composites.
