Comparison of Na+-MMT and Ca2+-MMT for the preparation and characterization of poly(ethylene-co-acrylic acid) inomer/MMT nanocomposites |
| 초록 |
Polymer/clay based composite films were prepared by incorporating sodium montmorillonite(Na+-MMT) and calcium montmorillonite(Ca2+-MMT) clay into poly(ethylene-co-acrylic acid)(PEAA). The dispersion of the MMT particles in the PEAA/MMT nanocomposites was investigated by TEM and XRD. The TEM results indicated that the average lateral dimension of the MMT particles in the PEAA/MMT nanocomposites was around 300nm and their thickness was less than 20nm. The PEAA chains were intercalated into the interlayers of MMT. The NH4+ ions on the PEAA chains were replaced by the Na+ or Ca2+ ions in the interlayer of MMT. The mechanical behavior of the PEAA/MMT nanocomposites with different contents of MMT was studied by means of an Instron. The thermal properties of the PEAA/MMT nanocomposites were also discussed with reference to the TGA and DTA curves. The TGA and DTA results confirmed that the presence of the Ca2+ ions allowed the PEAA to form a network. |
