  • Patent number: 9334387
    Abstract: The method for the preparation of epoxy-clay nanocomposites uses high shear mixing of Nanomer I.30 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. Increasing the degassing temperature from 65° C. to 100° C. for the first two hours of the degassing process enhanced nanoclay dispersion, resulting in nanocomposites with a morphology dominated by disorder intercalation with some exfoliated structure. This enhancement in nanocomposite morphology can be attributed to the improvement in epoxy diffusion into the intergallery spacing between clay layers due to temperature rise.
