Thermal Behavior of Clay/Epoxy Nanocomposites
In this work, the effect of curing agent, curing conditions and the incorporation of small amounts of organoclay on the thermal properties of DGEBA (diglycidyl ether of bisphenol A) epoxy resin was evaluated in order to develop an epoxy system for application as the matrix in active composites whose dispersed phase consists of shape memory alloy wires.

USB2 Method for preparation of epoxyclay ...
The method for the preparation of epoxyclay nanocomposites uses high shear mixing of Nanomer E nanoclay into the diglycidyl ether of bisphenol A (DGEBA) epoxy by optimization of high shear mixing speeds, mixing times and degassing temperature. The results showed that the optimum high shear mixing speed and mixing time for optimal clay dispersion were 6000 rpm and 60 min, respectively.

Epoxy Nanocomposites with Highly Exfoliated Clay ...
Epoxy/clay nanocomposites with a better exfoliated morphology have been successfully prepared using a socalled "slurrycompounding" process. The microstructures of the nanocomposites (epoxy/Sclays) were characterized by means of optical microscopy and transmission electron microscopy (TEM). It was found that clay was highly exfoliated and uniformly dispersed in the resulting nanocomposite.
