“…5), indicating that MgO did not significantly enhance the char residue but accelerated the thermal-oxidative decomposition of PC. 3,10 Based on the above results it can be concluded that MgO could accelerate the thermal-oxidative degradation process and promote the formation of char layer at the burning surface. The volatile in the pyrolysis acted as blowing agent and caused the swelling char-like layer at the burning surface.…”

“…3–10 Representatively, aromatic sulfonate compounds, 3,4,10 silicon compounds, 6,11 and phosphorus compounds 12,13 were reported to be effective flame retardant for PC. Despite, the above organic compounds are effective to retard flame of PC, the complex of synthesis as well as the possibility to release deleterious organic compound during burning make them nonfriendly to the environment.…”

A new flame retardant polycarbonate/magnesium oxide (PC/MgO) nanocomposite, with high flame retardancy was developed by melt compounding. The effect of MgO to the flame retardancy, thermal property, and thermal degradation kinetics were investigated. Limited oxygen index (LOI) test revealed that a little amount of MgO (2 wt %) led to significant enhancement (LOI = 36.8) in flame retardancy. Thermogravimetric analysis results demonstrated that the onset temperature of degradation and temperature of maximum degradation rate decreased in both air and N2 atmosphere. Apparent activation energy was estimated via Flynn–Wall–Ozawa method. Three steps in the thermal degradation kinetics were observed after incorporation of MgO into the matrix and the additive raised activation energies of the composite in the full range except the initial stage. It was interpreted that the flame retardancy of PC was influenced by MgO through the following two aspects: on the one hand, MgO catalyzed the thermal-oxidative degradation and accelerated a thermal protection/mass loss barrier at burning surface; on the other hand, the filler decreased activation energies in the initial step and improved thermal stability in the final period.

“…The intensities of the intrinsic bands further decrease so that some relative weaker bands disappear with the temperature further increasing to 400 C. The absorption band of carbonyl group at 1775 cm À1 shifts to 1745 cm À1 . These absorption bands are weakened significantly at 450 C, and the weak bands at around 3900e3500 cm À1 , 1600e1300 cm À1 , 1200e 1000 cm À1 , 625 cm À1 may be corresponding to polyaromatic substituted phenols [34]. The TG curve shows that PC only losses about 10 wt% at 450 C. It is concluded that some branched and crosslinked structures with various carbonyl groups, ether and unsaturated carbonaceous bridges are produced at the beginning of the thermal oxidative degradation.…”

“…However, these phosphates usually bring some proceeding problems such as the high processing temperatures and their different resin state. In addition, the use of organosulfonates in low concentration (no less than 1wt.%) was found to be effective in flame-retarding polycarbonate (PC) as a special case, such as potassium perfluorobutane sulfonate (PPFBS), potassium diphenysufonesulfonate [5]. However, the thermal degradation of PC/PPFBS composites was not found.…”

Potassium perfluorobutane sulfonate (PPFBS) was used to impart flame retardancy to polycarbonate (PC). The thermal properties of of the PC/PPFBS composites were studied by limiting oxygen index (LOI), vertical burning test (UL-94), TG, and scanning electron microscopy (SEM). The results showed that PC/1wt.% PPFBS composites passed UL-94V-0 rating, and its LOI values were 30.6%. Compared with PC, for the PC/PPFBS composites, the thermal stability and the char yield are increased. Scanning electron microscopy revealed that the char properties had crucial effects on the flame retardancy.
