Abstract:Brominated flame retardant polystyrene composites were prepared by melt blending polystyrene, decabromodiphenyl oxide, antimony oxide, multiwall carbon nanotubes and montmorillonite clay. Synergy between carbon nanotubes and clay and the brominated fire retardant was studied by thermogravimetric analysis, microscale combustion calorimetry and cone calorimetry. Nanotubes are more efficient than clay in improving the flame NOT THE PUBLISHED VERSION; this is the author's final, peer-reviewed manuscript.

Comparison of the results from the microscale combustion calorimeter and the cone calorimeter indicate that the rate of change of the peak heat release rate reduction in the microscale combustion calorimeter was slower than that in the cone. Both heat release capacity and reduction in the peak heat release rate in the microscale combustion calorimeter are important for screening the flame retardant materials; they show good correlations with the cone parameters, peak heat release rate and total heat released.

In this article, high impact polystyrene/organo Fe-montmorillonite (HIPS/Fe-OMT) nanocomposites were prepared by melting intercalation. The thermal stability of HIPS/Fe-OMT nanocomposites increased significantly compared to that of HIPS examined in thermal degradation conditions. Kinetic evaluations were performed by Kissinger, Flynn-Wall-Ozawa, Friedman methods and multivariate nonlinear regression. Apparent kinetic parameters for the overall degradation were determined. The results showed that the activation energy of HIPS/Fe-OMT nanocomposites was higher than that of HIPS. A very good agreement between experimental and simulated curves was observed in dynamic conditions. Their decomposition reaction model was a single-step process of an nth-order reaction.

“…Amine-based stabilizers, for example N,N′-di-2-naphthyl-p-phenylenediamine (DNP), capture free radicals (produced by oxidation) through dehydrogenation, yielding stable free radicals that can quench the free radicals generated continually during oxidation. This chemical process can be summarized as follows [43,44]:…”

Thermal-mechanical stability of ethylene tetrafluoroethylene alternating copolymer, and modification thereof

et al. 2012

View full text Add to dashboard Cite

It is generally accepted that ethylene tetrafluoroethylene alternating copolymers (ETFEs) are exceptionally thermal stable materials. However, we found that ETFEs will decompose to some extent when exposed to heat, especially above 300°C and during a dynamic shear process (thermal mechanical degradation, thermalstress-oxidation synergistic destruction). In this article, the dynamic mechanical degradation of ETFE was first verified by dynamic rheometry with the aid of IR analysis, then a facile, environmental friendly solutionnamely the addition of the antiaging agent N,N′-di-2-naphthyl-p-phenylenediamine (DNP)-was adopted to prevent the degradation. Rotational rheometry and thermogravimetry analysis results proved that this is an applicable strategy. The addition of DNP led to remarkable increases in the initial thermal decomposition temperature, dynamic shear stable duration time, and thermal decomposition activation energy of ETFE without sacrificing its mechanical properties.
