“…[3][4][5][6][7] In recent years, non-halogen flame-retardant PLA composites have already been extensively researched. [8][9][10][11] Several systems have been applied to impart flame retardancy to PLA, such as phosphorus-containing silsesquioxane, [12][13][14] intumescent flame retardants, [15][16][17][18][19] and nitrogen phosphorus flame retardants. [20][21][22][23][24] In addition to organic flame retardants, inorganic flame retardants including zinc aluminum layered double hydroxide, [25] carbon nanotubes, [26] sepiolite nanoclays, [26,27] nanosized carbon black combined with Ni 2 O 3 , [28] and inorganic nanoparticles [29][30][31] can effectively enhance flame-retardant properties of PLA.…”

The flame-retardant polylactic acid (PLA) has been prepared via mixing the flame retardant TGIC-DOPO derived from phosphaphenanthrene and triazine groups into matrix. The flame retardancy of TGIC-DOPO/PLA composites was characterized using the limiting oxygen index (LOI), vertical burning test (UL94), and cone calorimeter test. Results reveal that the 10%TGIC-DOPO/PLA composite obtained 26.1% of LOI and passed UL94 V-0 rating. The flameretardant mechanism of PLA composites was characterized via thermogravimetric analysis (TGA), pyrolysis gas chromatography/mass spectroscopy, and TGA-Fourier transform infrared. It discloses that TGIC-DOPO promoted PLA decomposing and dripping early, and it also released the fragments with quenching and dilution effects. These actions of TGIC-DOPO contribute to reducing the burning intensity and extinguishing the fire on droplets, thus imposing better flame retardancy to PLA. When TGIC-DOPO was partly replaced by melamine cyanuric with dilution effect and hexa-phenoxy-cyclotriphosphazene with quenching effect in composites respectively, the results confirm that TGIC-DOPO utilize well-combination in dilution effect and quenching effect to flame retard PLA.

“…As the PCL content was increased, the intensity of the melting peak for PLA also increased, indicating an increase in crystallinity . The nearly flat melting exotherm of the neat PLA may be further explained by the fact that several independent studies have reported that when PLA is cooled from melt, no PLA crystals will grow in such material, hence its largely amorphous nature.…”

Blends of polylactide (PLA) and poly(ϵ‐caprolactone) (PCL) were melt‐processed with boehmite (BAI) nanoparticles to produce ternary biocomposites with the intent of broadening the potential applications of PLA. The mechanical properties of the prepared composites exhibited remarkable improvement in the elongation‐at‐break of between 60 and 430% for increasing loadings of PCL and BAI in the blends. Furthermore, the melting temperatures of PLA and PCL were observed to shift approximately 2 °C toward each other in the composites, an indication of improved compatibility. This partial compatibility was also observed from the electron microscopy images, which also revealed a good dispersion of PCL in the PLA. The composite with balanced properties was found to be consisting of 70 wt% PLA, 30 wt% PCL, and 4 wt% BAI.

“…It was reported that all the PLA composites with 15 wt% IFR showed excellent flame retardancy in the UL-94 burning test (i.e., V-0 rating), regardless of the carbon source(s) used. According to another study of Fox et al [45], both APP/NFC and APP/ PNFC yielded remarkable reduction in the PHRR and THR during CCM experiments through extensive char formation. This indicates that NFC and PNFC may be effective natural carbon sources in IFR formulations.…”
