Abstract
The results of physical studies of nanostructure, dynamics, mechanical and thermal properties of DCBE-based CER/amino-MMT nanocomposites are presented. The 2D MMT nanolayers content in these composites varied from 0.01 wt.% to 5 wt.%, and their analysis was performed by TEM, EDXS, mid-IR, far-IR, XRD, DSC, DMA, CRS, and TGA methods. The process of MMT exfoliation increased with decreasing MMT content in the composite, down to the formation of individual nanolayers at 0.1 wt.%. The ambivalent influence of MMT nanolayers on matrix dynamics, Tg, and thermal stability is shown, with the most positive effect at small and ultra-low MMT contents (0.025–0.5 wt.%). Anomalous composition and mechanical properties of the subsurface micron layers in the CER-based nanocomposites were detected.
