New nanocomposites constituted of polyethylene and organically modified ZnAl-hydrotalcites

摘要

The thermal properties and combustion behaviour of new PE-hydrotalcites nanocomposites are described. Hydrotalcites were synthesized and then intercalated with stearate anion, because of the compatibility of long alkyl chain with polyethylene chains. The presence of inorganic filler shields PE from thermal oxidation, shifting the temperature range of volatilisation towards that of thermal degradation in nitrogen, and brings to a reduction of 55% in heat release rate during combustion.
