1,2, 3‐Triazole rich polymers for flame retardant application: A review

Development of the non-halogenated flame retardants (FRs) is an emerging research area as halogenated FRs are prone to produce carcinogenic and persistent organic pollutants. In this context, 1,2,3-triazole synergized FR polymeric materials noticeably attained great interest in the last decade. The mini-review highlights the role of azide-alkyne click chemistry with specific reference to 1,2,3-triazole moiety covalently grafted FR for various polymeric systems. In particular, the intumescent FR mechanism of 1,2,3-triazole has been reviewed and the technical evidence for the mechanism is provided by fourier transform infrared spectroscopy (FTIR), energy-dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS) analysis. 1,2,3-triazole moiety is increasingly proving itself to be a potent non-halogenated FR and it has the potential to be adopted by the industry in near future.
