AbstractDevelopment 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.
