In the last decade, few-layer boron nitride nanosheets and monolayer BN nanosheet (BNNS) have gained much attention due to their unique physical and chemical properties. To date, BNNS can be produced by micromechanical cleavage of BN crystal, unzipping BN nanotubes, chemical vapor deposition (CVD), and solution processed exfoliation from bulk BN powder. Due to the low cost and abundance of bulk BN powder and its simple processing for potentially scalable production, great efforts have been devoted toward solution processed exfoliation. In this feature article, recent significant advances in solution processed synthesis of BNNS are summarized. In particular, the solvent choice for one-step BN exfoliation is highlighted. Multi-dimensional assemblies consisting of BNNS are discussed, such as BN fiber, BN paper, and BN aerogel. The emerging applications of BNNS in different fields are then focused on, especially in barrier materials, dielectrics, catalysts, and thermal management.For a long time, BN has been utilized in lubricants, cosmetics, paints, cements and high-temperature equipment due to its unique properties, including high thermal conductivity and great chemical stability. [4] With the discovery of monolayer graphite (graphene) and its extraordinary physical properties, [5] the past decade has witnessed a large growth of research interest in few layer or monolayer 2D layered materials, [6] such as MoS 2 , [7] Bi 2 Se 3 , [8] and black phosphorous. [9] Due to their wider energy band gaps and electrically insulating properties compared to graphene, few layer and monolayer BNNS have stimulated great research interest, [10] allowing a much wider range of applications than their bulk counterparts. For example, BNNS can be an appealing substrate for graphene devices due to the similar lattice constant and atomically smooth surface, where graphene exhibi ted a very high mobility [10c] and a rotation-dependent moiré pattern. [11] To date, strategies for synthesizing BNNS can be generally classified into two methods: bottom-up and top-down methods. In the bottom-up strategy, BNNS are fabricated from atoms, ions, or molecules, where the chemical vapor deposition (CVD) method is usually adopted. In this area, a significant progress for the technology was made by Kong's group, who has developed a relatively mature recipe for synthesizing BNNS via CVD. [10a] On the other hand, top-town methods for synthesizing BNNS typically involve the micromechanical cleavage of bulk BN crystals [12] or unzipping of BNNT. [13] Although these methods produce relatively high quality BNNS, the low yield and high cost have significantly limited their scalability. In contrast, BNNS made from bulk BN powder by solution processed exfoliation exhibit three important advantages. [14] (i) As raw material, bulk BN powder is abundant and cost-effective. (ii) A relatively high yield can be obtained due to its simple process. (iii) Functional groups on BNNS by solution processes facilitate the use of BNNS in various fields. All these advant...

“…A clear decrease in both properties occurred at 1.0 wt%, a drop by 5.3%, and 4.0% in EL and T, respectively. Such decreases at high loading content are often observed and associated to the agglomeration of the nanomaterials 1,67 suggesting the mixing process used here is not optimized for high loadings.…”

“…Furthermore, the second nanomaterial can not only improve the properties of the nanocomposites, but also increase the nanomaterials’ dispersion within the matrix. Hybrid nanomaterials such as clay with MWNT, graphene with MWNT, and MWNT with carbon black have exhibited remarkable synergetic effects while enhancing the properties of the nanocomposites . Zhang and coworkers, reported that the tensile strength of poly(vinyl alcohol) composites with MWNT and a hybrid graphene filler (0.6 wt %) were 20% and 34% higher than those of composites filled with the same amounts of MWNT and graphene alone, respectively.…”

Elastomer nanocomposites reinforced with carbon nanofiber (CNF) decorated with metal nanoparticles exhibit excellent thermal, mechanical, and magnetic properties with low volume fraction of the reinforcement. Generally, metal nanoparticles are used to modify the surface of CNF, to improve their dispersion and contact resistance in the polymer matrix. In this study, Fe 2 O 3 metal nanoparticles were decorated on CNF by electrostatic attraction via a green and facile solution-based method. Interestingly, the CNF decorated with Fe 2 O 3 (CNF-Fe 2 O 3 )/elastomer improved both the tensile strength and the fatigue property of plain CNF/elastomer by as much as 57.2% and 27.2%, respectively. Moreover, the CNF-Fe 2 O 3 /elastomer exhibited superior thermal conductivity, a twofold enhancement compared with carbon fibers. The elastomer nanocomposites consisting of CNF-Fe 2 O 3 also exhibited enhanced magnetic properties due to synergies between the Fe 2 O 3 nanoparticles and the CNF. The elastomer nanocomposites prepared with CNF-Fe 2 O 3 will open significant new opportunities for preparing advanced elastomer nanocomposites for future engineering applications.
