“…24 Typically, hyper-branched polyphosphonate acrylate is synthesized as a flame retardant by employing an A2B3 type polymerization, where di(acryloyloxyethyl) benzenephosphonate (DAMP) containing two vinyl groups is used as an A2 component and AEPZ is used as a B3 component. 25 Inspired by this idea, functionalized graphene with AEPZ is prepared via surface modification; subsequently, hyper-branched polymer functionalized GO (FGO) is synthesized by in situ polymerization among AEPZ, DAMP and AEPZ modified GO. FGO is blended with the different ratios of polyethylene (PE) to prepare a series of FGO/PE composites.…”

In this work, GO was functionalized by a hyper-branched flame retardant, which was synthesized by the reaction of N-aminoethyl piperazine and di(acryloyloxyethyl)methylphosphonate. Subsequently, the resultant functionalized GO (FGO) was incorporated into the cross-linked polyethylene (XLPE) to enhance the flame retardancy of the matrix. Transmission electron spectroscopy images indicated that FGO exhibited uniform dispersion in XLPE matrix and strong adhesion with the matrix by crosslinking, which improved barrier effect due to reduced heat release and the free radical transfer between the matrix and graphene nanosheets. The incorporation of FGO into XLPE matrix endowed polymer composites with flame retardancy and thermal stability. In addition, the homogeneous dispersion of functionalized GO with a hyper-branched flame retardant in the polymer matrix improved the antioxidation and mechanical properties of XLPE−FGO nanocomposites compared to the XLPE− GO samples, as demonstrated through the oxidative induction temperature and time test, oven ageing test and mechanical test.

Hu and colleagues 85,88,89 prepared UV-curable intumescent FR coatings by blending TAEP in certain ratios with star poly(urethane acrylate, SPUA), in which combustion properties were studied via microscale combustion calorimetry (MCC) experiments. In continuation, two novel FR monomers used for UV curing systems N,N#-bis(2,4-di(acryloyloxyethyl)-[1,3,5]-triazin-2-yl)-hexane-1,6-diamine (BDAETH) and 2,2-dimethyl-1,3-propanediol glycerol-methacrylate phosphate (PGMH) were synthesized, which was blended in different ratios to prepare a series of UV-curable intumescent FR coatings.…”

Flame retardants are chemical compounds when mixed or incorporated in to polymers provide varying degrees of flammability protection. Flammable polymeric materials are ubiquitous with a wide array of applications. However, recent studies have shown potential environmental and health concerns with certain halogen-containing flame retardants. Thus, it has now become a necessity to explore new and effective materials that are safer and environmentally benign. In this context, halogen-free phosphorus- and nitrogen-containing flame retardants have attracted much attention worldwide. Moreover, s-triazine is the central focus because of its excellent charring effect. General strategies for synthesizing s-triazine compounds mostly via nucleophilic substitution reaction have been highlighted. This review provides a comprehensive description on design and synthesis of flame-retardant materials with significant flammability performance.

The 21st century is the century of advanced technologies, innovations, smart ideas and smart solutions, yet it is still challenging and demanding. From the perspective of material sciences, today there are still several problems that need to be addressed. Fire retardancy is found on top of the list of these challenging problems. Fire retardancy, which has become one of the most wanted requirements for several materials, is not only an issue of today's technology, but also that of the past and future. This chapter will focus on the fire-resistant photocurable materials, especially on phosphorus- or boron-containing photocurable coatings. First, a brief introduction to flame retardancy will be presented and then the recent progress in the development of phosphorus or boron containing flame-retardant photocurable coatings will be reviewed. Phosphorus- or boron-containing monomers and additives used in photocurable coatings will be summarized and their effectiveness will be discussed.
