“…The atomic concentrations in the spots, sp2 and sp3, for the seed nanoparticles are 86.0% and 63.8% with the Cu balance (from the grid) and also N (17.9%) for the latter. This agrees well with the literature [22,34] that the seed Fe nanoparticles produced from the crystalline boron are encapsulated by disordered boron synthesizing BN during annealing. The atomic ratio at sp1 is B(35.4%):N(42.8%), and B(18.9%):N(79.6%) for sp4, while N is much richer in the spot, sp4, shown in the inset image in Figure 6c.…”

“…Furthermore, the crystallographic structure of boron coated on the surface of the catalytic precursor nanoparticles produced from the milling of crystalline boron was found to be a key factor for BNNTs synthesis [22,34]. Upon these fundamental findings, we explored the B/Fe interdiffused precursor nanoparticles produced from the ball milling of a mixture of amorphous boron, which with Fe can reduce the Fe impurity, while increasing the production yield of BNNTs compared to the crystalline boron-based precursor.…”

Enhancement of the production yield of boron nitride nanotubes (BNNTs) with high purity was achieved using an amorphous boron-based precursor and a nozzle-type reactor. Use of a mixture of amorphous boron and Fe decreases the milling time for the preparation of the precursor for BNNTs synthesis, as well as the Fe impurity contained in the B/Fe interdiffused precursor nanoparticles by using a simple purification process. We also explored a nozzle-type reactor that increased the production yield of BNNTs compared to a conventional flow-through reactor. By using a nozzle-type reactor with amorphous boron-based precursor, the weight of the BNNTs sample after annealing was increased as much as 2.5-times with much less impurities compared to the case for the flow-through reactor with the crystalline boron-based precursor. Under the same experimental conditions, the yield and quantity of BNNTs were estimated as much as ~70% and ~1.15 g/batch for the former, while they are ~54% and 0.78 g/batch for the latter.

“…Recently, the effect of the initial shape of boron coated on the Fe seed particles on the growth of BNNTs was investigated [15], while only a few offer the root mechanisms of the synthesis and growth of BNNTs. In this study, we explored the aspects of the mechanical activation energy transferred to milled boron powder producing structural disorder and borothermal reaction of the ZrO 2 seed particles on the synthesis of BNNTs.…”

Boron nitride (BN) is an eminent inorganic compound having many interesting characteristics such as improved oxidation resistance, mechanical strength, good thermal conductivity (TC), higher bandgap, high chemical stability, thermal stability, high hydrophobicity, and electrical insulation. The use of BN as a filler in polymers is a well‐established strategy to tailor the properties of polymer composites. Recent studies depict an interesting urge to reap the synergistic effect of various nanofillers with BN in the form of hybrids. Hence the consolidation of the works on BN based hybrid fillers would definitely attract researchers so that these new filler systems could be transformed into useful polymer nanocomposites in future. This review article focuses on the synthesis and characterization of various boron nitride based hybrids in detail. Moreover, the review also throws light on different BN hybrid reinforced polymer nanocomposites (PNCs) and their thermal, electrical, electronic as well as biomedical applications in a detailed manner. Thus the review anticipates serving as a tool toward understanding the recent trends in the field of boron nitride hybrid based ternary polymer composites.
