Optimization of Flame Retardant System For Bamboo Fiber Composites: Effect of Flame Retardant Content

Journal of Natural Fibers
From an economic standpoint, compound flame retardants are the optimal solution for industrial flame-retardant material production. While flame retardant content is a critical parameter for system performance optimization, existing research has primarily

Synthesis of a Phosphorus/Nitrogen-Containing Additive with Multifunctional Groups and Its Flame-Retardant Effect in Epoxy Resin

, 2015
A novel additive, tri(phosphaphenanthrene-maleimide-phenoxyl)-triazine (DOPO-TMT), was successfully synthesized. The chemical structure was characterized by Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance.

Polarization‐Reoriented Piezocatalysis Enables Plastic Upcycling with Mechanical Energy

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mixed plastic waste remains difficult to upcycle selectively under mild conditions, and piezocatalysis has been constrained by a persistent see‐saw effect: Stronger piezoelectric polarization tends to divert charge carriers away from the very active sites that drive catalysis. Sha et al.

Phosphorus flame retardants with different chemical environment. Thermal stability and flame-retardant efficiency

, 2022
16Engineering plastics (PA, PBT) have their own high processing temperatures (250-350°C and even higher). To realize fire-resistant polymers it is necessary to compound polymers and flame retardants at these temperatures without a serious change in the ...

Oxidant‐Expedited Synthesis of H‐Phosphonates

European Journal of Organic Chemistry, EarlyView.
An exceptionally mild method for synthesis of alkyl and aryl H‐phosphonates from phosphites is reported, requiring only water and O2 (including air) as reagents. Mechanistic experiments indicate that the role of O2 (and other oxidants) in the transformation is to promote a radical mechanism, and that H2O functions to provide both the hydrogen and the ...

Synergistic effect between a novel triazine‐based flame retardant and DOPO/HPCP on epoxy resin

, 2018
In this paper, a triazine-based flame retardant (TAT) was synthesized from cyanuric chloride and aniline. Its chemical structure was characterized by Fourier transform infrared (FTIR) spectroscopy, 1H nuclear magnetic resonance, and elemental analysis ...
