    Abstract

    Two epoxy/organoclay nanocomposites were synthesized in-situ with both thermal and microwave heating methods. The epoxy materials are diglycidyl ether of bisphenol A (DGEBA)/ m-phenylenediamine (mPDA) and DGEBA/ diethyltoluenediamine (Epi-cure W). Transmission Electron Microscopy (TEM) results revealed the coexistence of intercalated and exfoliated clay layers in both epoxy systems. In in-situ synthesis of nanocomposites, the clay interlayer distance increases with the progress of intragallery (i.e. interlayer) reaction, and suppressed by the extragallery reaction. Higher degree of exfoliation could be obtained for systems with higher diffusion rate into the clay interlayer. Microwaves improved the exfoliation for both epoxy nanocomposites, possibly because the direct absorption of microwave energy by the reactive molecules enhanced their diffusion into the clay interlayer. When mPDA was used as the cure agent, microwave cured nanocomposites had similar Tg and lower storage modulus compared with thermally cured nanocomposites. When Epi-cure W was used as the cure agent, microwave cured nanocomposites had higher Tg and similar storage modulus compared with thermally cured nanocomposites.
