“…In air atmosphere, the degradation of the principal TPU chains, the further degradation of polyols and isocyanates, and oxidation of the char residue are corresponding to 3 thermal degradation steps of pure TPU, respectively. From the results presented by Table , TPU/CTAB‐BN composites show a lower initial degradation temperature than pure TPU, which is consistent with previous literature . It is possibly attribute to the high thermal conductivity of BN nanosheets, which facilitates the transmission of heat.…”

Although hexagonal boron nitride (h‐BN) has presented a potential prospect in polymer composite fields, undesirable interfacial interaction with polymer matrix that generates serious aggregation of nanomaterials has suppressed its enhancement effect. Moreover, the chemically inert surface of h‐BN also makes the commonly used approach that improves the interfacial interaction between nanofillers and polymeric matrix invalid. Herein, the functionalized modification of chemically inert h‐BN was successfully fabricated by the adsorption of cetyl‐trimethylammonium bromide, with electrostatic interactions. The obtained h‐BN (cetyl‐trimethylammonium bromide‐BN) was well characterized by systematic tests and then added into thermoplastic polyurethane (TPU) matrix. The inclusion of functionalized h‐BN can dramatically improve thermal stability, flame retardant, and mechanical properties of TPU composites. With the incorporation of as low as 4.0 wt% nanofillers, maximal value of heat release rate and total heat release of TPU were reduced by 57.5% and 17.8%, compared with those of pure TPU, respectively. Moreover, tensile strength of TPU composite with a loading of 2.0 wt% was increased by 79.3% in comparison with that of neat TPU. The facile functionalized approach of chemically inert h‐BN paves the way for promising applications of h‐BN in the development of flame retardant polymer materials.

“…As observed in Figure B2, the incorporation of FGNS led to a more roughly fractured appearance in PAN/FGNS‐3.0 fiber. This phenomenon indicated that the FGNS formed a strong interfacial interaction with PAN matrix . Furthermore, no existence of FGNS aggregation declared the good dispersion and embedding of FGNS in PAN matrix.…”

Functionalized graphene has a promising prospect in improving the thermal, mechanical, and flame‐retardant properties of polymer composites, which was unfortunately limited by the low yield and high pollution during graphene production. In this study, we reported a facile and eco‐friendly electrochemical approach to prepare ferric diethylenetriaminepentakis (methylphosphonic acid) functionalized graphene nanosheets (FGNS), which were subsequently used to fabricate polyacrylonitrile (PAN) composite fibers by a wet spinning strategy. Composite fibers showed better thermal stability above 350°C in contrast to pure PAN. Furthermore, a significant improvement on flame‐retardant properties of PAN fibers in the case of peak heat release rate (decreased by 36.7%) was caused by the inclusion of FGNS. The analysis results of condensed phase revealed that FGNS facilitated the formation of the compact and graphitic char residues, protecting underlying composite fibers during combustion. With adding 3.0 wt% FGNS, the tensile strength and breaking elongation of PAN composite fibers achieved 67.6% and 126.5% increment, respectively. This electrochemical method provides an eco‐friendly approach for scale production of functional graphene.

“…A new and broad peak near 2850 cm −1 appeared for BP nanosheets, which is attributed to the stretching vibration of O—H bonds, resulting from the reaction between water and oxygen and P atoms (Figure a). The diffraction peak intensity in XRD curves is positively correlated to the ordered restack degree of nanosheets . From the XRD results of bulk BP and BP nanosheets, characteristic peaks at 16.9°, 34.2°, and 52.3° were detected, which correspond to 020, 040, 060 planes, respectively (Figure b) .…”

Solar vapor generation is a promising and whole new branch of photothermal conversion for harvesting solar energy. In this work, a novel solar vapor generator based on black phosphorous (BP) nanosheets is designed for steam generation, desalination, as well as dye removal, using polyurethane (PU) foam as a supporting material. Employing electrostatic layer‐by‐layer assembly, BP nanosheets and chitosan (CS) are alternately deposited onto the skeleton of the PU foam. After the deposition of BP nanosheets, the hydrophilicity of the PU composite foam is obviously improved, thus facilitating the capillary effect. Even with a spot of BP nanosheets (lower than 5.0 wt%), the as‐fabricated PU@(sodium alginate, SA/BP)6 foam exhibits a surface temperature of ≈70.9 °C and an evaporation rate of 1.082 kg m−2 h−1 under 1 sun irradiation. Due to the protection effect of CS, the photothermal conversion performance and water evaporation rate do not deteriorate during ten cycles of reusing. In addition, the water evaporation performance of PU@(SA/BP)6 is also investigated under different conditions, including sun irradiation intensity, metal ions, and dye. In brief, employing a facile and eco‐friendly fabrication process, BP nanosheets are first applied to seawater desalination and pollution removal, presenting a tremendous potential for practical solar vapor generation.
