Thermoset polymers are frequently used as matrices for nanocomposite materials because nanofillers, such as clay, can be easily incorporated into liquid polymer precursors. Since in the crystal structure of clay such as Montmorillonite the layers are physically linked by cations, replacing these cations with larger organophilic molecules changes the clay surface into hydrophobic and increases the...
The purpose of this work is to demonstrate the post-treatment importance using dielectric measurements on nanocomposites. During this post-treatment which is the application of heat over time, crosslinking completes and ageing sets in. Both effects usually take place in the same time. Besides the expected differences between the filled and unfilled epoxy samples, the influence of silane coupling agents...
