“…They are combined with other substances to usually improve the char formation or oxidative durability of the char formed by the phosphorus flame retardant. Compared to brominated retardants, there are fewer reactive versions of phosphorous flame retardants; however, only 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) is widely used commercially [ 49 , 80 , 81 , 82 , 83 , 84 , 85 ].…”

Currently, polymers are competing with metals and ceramics to realize various material characteristics, including mechanical and electrical properties. However, most polymers consist of organic matter, making them vulnerable to flames and high-temperature conditions. In addition, the combustion of polymers consisting of different types of organic matter results in various gaseous hazards. Therefore, to minimize the fire damage, there has been a significant demand for developing polymers that are fire resistant or flame retardant. From this viewpoint, it is crucial to design and synthesize thermally stable polymers that are less likely to decompose into combustible gaseous species under high-temperature conditions. Flame retardants can also be introduced to further reinforce the fire performance of polymers. In this review, the combustion process of organic matter, types of flame retardants, and common flammability testing methods are reviewed. Furthermore, the latest research trends in the use of versatile nanofillers to enhance the fire performance of polymeric materials are discussed with an emphasis on their underlying action, advantages, and disadvantages.

“…Among the reactive approach, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and DOPO derivatives are the research focus. [11][12][13][14][15][16] Wang et al [17] synthesized a kind of DOPO derivative called 6-((bis [2-hydroxyethyl]amino)methyl)-6H-dibe-nzo[c,e] [1,2] oxaphosphinine-6-oxide and subsequently used as a reactant for synthesizing a flame retardant alkyd resin. The results showed that the flame retardancy of alkyd resins was improved.…”

Two novel flame retardant and anti-dripping PE films were successfully synthesized in three steps. PEg -GMA film was first prepared by simultaneous electron beam irradiation to graft glycidyl methacrylate (GMA) onto PE film. 4,4 0-[1,4-phenyl-bis(9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-yl) dimethyneimino)]diphenol (DOPO-t) and 4,4 0-[1,3-phenyl-bis (9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-yl)dimethyneimino)]diphenol (DOPO-m) were then fabricated via a one-pot method. Finally, two DOPO derivative functionalized PE films were obtained through the ring opening reactions of PEg -GMA film with DOPO-t and DOPO-m, respectively. Combustion properties, flame retardancy, thermal performance, and thermal shrinkage of these films were evaluated. Compared with pure PE film, the burning rate of antidripping DOPO-t/DOPO-m functionalized PE films was reduced by 13.2% and 50.0%, and the limiting oxygen index value climbed to 18.5 and 19.5, respectively. The residual chars from DOPO-t/DOPO-m functionalized PE films at 700 C were increased, and the shrinkage ratio decreased remarkably, which could effectively prevent the spread of fire. We also discussed the effect of structural difference between DOPO-t and DOPO-m on the above properties and the flame retardant mechanism of two DOPO derivative functionalized PE films preliminarily. This work provides a method for introducing DOPO derivatives into PE molecules to improve their flame retardancy and anti-dripping properties.

“…For instance, the incorporation of DOPO groups into the structure of bi-functional monomers results in polymers with good solubility, improved thermal stability, flame retardant properties, good adhesion and decreased birefringence. [35][36][37][38][39][40][41][42][43][44][45][46][47] To date, several papers described the preparation of phosphorus-containing hyperbranched polymers appealing for flame retardancy applications. [48][49][50][51][52] As a rule, a high content of phosphorus in a polymer brings better fire performances, thus, current work aimed to prepare hyperbranched polyesters derived from A 2 and B 3 monomers, as a facile route to novel phosphorus-containing hyperbranched polyesters.…”

Liquid crystalline hyperbranched poly(aryl ester)s (A2B3) were prepared by polycondensation reaction of 2-(6-oxido-6H-dibenz<c,e><1,2>oxaphosphorin-6-yl)1,4-naphthalene diol with 1,3,5-benzenetricarbonyl trichloride, taken in two different molar ratios. The chemical structure of the newly synthesized hyperbranched polymers was confirmed by FTIR, 1H NMR, 13C NMR spectroscopy. The polymers exhibited high thermal stability with initial decomposition temperature above 410–435°C and char yield at 700°C higher than 40%. Combined differential scanning calorimetry, polarized optical microscopy and wide-angle X-ray diffraction measurements were carried out to closely examine their thermal behavior and phase transitions.
