| Abstract: | Na montmorillonite was modified by ion exchange reaction with organ amine,the epoxy clay nanocomposites were prepared by fully stirring clay modified and epoxy with the bisphenol A structure casting in heating. Various factors affecting the material formation were discussed. TGA, XRD, TEM and DMA were applied to characterize the structure and properties of composites and formation mechanism was also preliminarily explored. The results from quantitative computation indicate that the driving force of forming the nanocomposites resulted from curing reaction heat of epoxy in the galleries of montmorillonite. |
