Crystallinity and thermal stability of LDH/polypropylene nanocomposites

Polypropylene nanocomposites were prepared with Mg–Al layered double hydroxide (LDH) intercalated with dodecylsulfonate/itaconic acid. We investigated the influence of the organo-LDHs on some properties of the nanocomposites, such as crystallinity, thermal stability and combustion performance. The nanocomposites were characterized by means of X-ray diffraction, transmission electron microscopy and thermogravimetric analysis. The addition of the LDHs increased the crystallinity of the polypropylene and thermal stability of the nanocomposites and retarded the flammability.
