“…Textile is a major application for PLA and it is also required to achieve flame retardancy. The flame retardancy of PLA fabrics were investigated by Kubokawa et al [37][38][39] using conventional FR treatments measuring the limiting oxygen index (LOI measured according to the ASTM Standard Method D2863-97). Untreated PLA fabric was measured at 24 vol% and when treated with several bromine-containing flame retardants and a phosphoruscontaining flame retardant, triphenylphosphate (TPP), LOI increases slightly to 28 vol% with TPP and to 26 vol% with the bromine-containing FR (tetrabromobisphenol A or TBP-A which was revealed to be the most efficient).…”

“…Bourbigot and Fontaine reported ammonium polyphosphate (APP) usage increased flame retardancy for polyamides and polyesters. In the studies of Kubokawa et al, results showed flame retardancy of PLA slightly improved with triphenyl phosphate (TPP). In another study, Lin et al showed aluminum hypophosphite loading enhanced flame retardancy of PLA/PC blends.…”

Summary The purpose of this study is to increase of the flammability properties of the glass fiber (GF)–reinforced poly (lactic acid)/polycarbonate (PLA/PC) composites. Ammonium polyphosphate (APP) and triphenyl phosphate (TPP) were used as flame retardants that are including the organic phosphor to increase flame retardancy of GF‐reinforced composites. APP, TPP, and APP‐TPP mixture flame retardant including composites were prepared by using extrusion and injection molding methods. The properties of the composites were determined by the tensile test, limiting oxygen index (LOI), differential scanning calorimetry (DSC), and heat release rate (HRR) test. The minimum Tg value was observed for the TPP including PLA/PC composites in DSC analysis. The highest tensile strength was observed in GF‐reinforced PLA/PC composites. In the LOI test, GF including composite was burned with the lowest concentration of oxygen, and burning time was the longest of this composite. However, the shortest burning time was obtained by using the mixture flame retardant system. The flame retardancy properties of GF‐reinforced PLA/PC composite was improved by using mixture flame retardant. When analyzed the results of HRR, time to ignition (TTI), and mass loss rate together, the best value was obtained for the composite including APP.

Because of good thermal stability, nonflammability and rich structural designability, ionic liquids (ILs) have been used as flame retardants for poly(lactic acid) (PLA). However, as a small molecule, IL has the disadvantages of poor thermal stability and water resistance, and so on. In this paper, an imidazole‐type poly(ionic liquid) (PIL) containing a phosphate anion was synthesized using 1‐vinylimidazole, triethyl phosphate, and 1,2‐divinylbenzene and marked as PDVE[DEP]. The PDVE[DEP] was used to improve the flame retardancy of PLA. The flame retardancy and thermal degradation behaviors of PLA/PDVE[DEP] composites were investigated by the limited oxygen index (LOI), UL‐94 vertical burning, cone calorimetry, and thermal gravity analysis, and so on. The results showed that only 1.0 wt% PDVE[DEP] allows PLA to achieve the UL‐94 V0 rating and obtain LOI value 25.6 vol%. The PDVE[DEP] improve the flame retardancy of PLA by melting‐away mode. In addition, it catalyzes the transesterification of PLA and changes the degradation products.
