Abstract

Poly(ethylene)/zinc copper hydroxy stearate (PE/ZCHS) nanocomposites were prepared via melt intercalation. Their structural morphology, thermal stability, and flammability were investigated using X-ray diffraction (XRD), thermogravimetric analysis (TGA), and cone calorimetry. Addition of zinc copper hydroxy stearate at mass percentages of 10 and below resulted in the shift of degradation temperatures to higher magnitudes. At the 10% mass loss point in TGA, the 5 and 10% loaded polymer nanocomposites are thermally more stable than pure PE by 59 and 48°C respectively. Peak heat release rates in cone calorimetry also decrease upon 5 and 10% loadings of ZCHS. Overall, the addition of 5% ZCHS generally led to better thermal and fire properties compared with PE alone or 10% additive loading.
