| Melt processed nanocomposites based on MXD-6 and four different nanoclays were studied. Low nanoclay loadings yielded more disordered, exfoliated nanocomposites while higher nanoclay loadings resulted in well ordered intercalated hybrids. The storage modulus for the nanocomposites increased with nanoclay loading. It was higher at temperatures both above and below the glass transition temperature of the polymer, though the increase was more pronounced above Tg. The glass transition temperature and tensile modulus also increased with nanoclay content. Minimal effects were seen on elongation and stress at break. DSC studies indicate that the crystallinity of the polymer in the nanocomposites initially increased and then decreased as the nanoclay content increased. |
