“…It is well known that EP has poor fire resistance, which will produce a serious of security risks and limit its application . Moreover, the application of metal‐doped flame retardant in epoxy resin is relatively few . So, it is important to research the flame retardance of metal‐doped epoxy resin.…”

Two novel Salen‐DPCPs metal complexes (Salen‐DPCP‐1 and Salen‐DPCP‐2), containing both Salen‐Schiff base (Salen), phenyl phosphate structures (DPCP) and nickel component, were prepared to reduce fire hazards of epoxy resin (EP). The results showed that 5 wt % addition of Salen‐DPCP‐1 brought a higher flame‐retardant efficiency to the EP, where the V‐0 rating in UL‐94 burning test and 31.5% of limiting oxygen index (LOI) were achieved. Meanwhile, total heat release, total smoke production, and total CO yield dramatically decreased by 28.1, 23.6, and 21.4%. In addition, these results basically reappeared when Salen‐DPCP‐2 were introduced into EP to obtain Salen‐DPCP‐2/EP composites. Chemical structure and morphology characterization of the carbon residue confirmed that Salen‐DPCPs improved the catalytic charring ability and the noncombustible gas releasing ability by the Fourier transform infrared, X‐ray photoelectron spectroscopy, and Scanning electron microscopy technology. Therefore, it is an efficient strategy to develop novel Salen composites modified by flame‐retardant groups to improve the fire rating of polymers. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

“…For all samples of the C 1s spectra ( Figure S4, Supporting Information), the numbers and positions of the peaks are the same. The peaks at about 284.6 eV assign to C-H and C-C in aliphatic and aromatic species in the char layer [37]. The bands around 285.8 eV are the contributions of C=N in heterocyclic compounds [38][39][40].…”

In this study, montmorillonite (MMT) was used as an inorganic synergist to prepare the water-based intumescent flame retardant (IFR) ornamental coating for plywood. Results indicate that the 7 wt.% MMT modified IFR coating (No. 3) possess the best fire resistance (longer than 20 min) of the tested samples according to the fire performance, which significantly declines the specific extinction area by 44.12 m2·kg−1 compared to the coating without MMT by cone calorimeter. In addition, characterizations such as XPS, XRD, TG, SEM and FTIR were characterized to investigate the surface and bulk properties as well as the morphology of MMT synergized water-based IFR coating. It is revealed that the residual nitrogenous polyaromatic structure and 25.5% residual mass in the No. 3 coating are a result of the effect of MMT on the antioxidation properties of the char layer.

“…The 2D structure of h-BN is very similar to the graphene layer bonding with two different chemical species of boron and nitrogen atoms. It displays excellent thermal conductivity, good mechanical properties, and excellent chemical stability [7][8][9][10]. It had been widely used as solid lubricant in cosmetics, thermal conductivity filler in polymer, and additive materials in the ceramics and aerospace field.…”

A hexagonal boron carbon nitride hybrid (h-BCN) is developed by in situ high-temperature solid-state reaction and subsequent chemical reduction with hydrazine. The XRD and TEM results show that the h-BCN features interlayered structures with two characteristic d-spacing of 0.33 and 0.21 nm. The obtained h-BCN exhibits significant electrochemical sensor for dopamine and uric acid. The cyclic voltammetric and amperometric experiments revealed a good linear relationship between current densities and concentrations of dopamine (DA) of 10-300 μM and uric acid (UA) of 10-500 μM, with high sensitivities of 0.14 μA/μM and 0.32 μA/μM and detection limits of 5 μM and 2 μM, respectively.
