TLDR
In this paper, a hybrid epoxy nanocomposites modified with carboxyl-terminated butadiene acrylonitrile (CTBN) rubber and organoclay were synthesized.Abstract:
Hybrid epoxy nanocomposites modified with carboxyl-terminated butadiene acrylonitrile (CTBN) rubber and organoclay were synthesized. The morphology of those nanocomposites was studied with X-ray diffraction (XRD), Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM). The results showed that most of the organoclay in the nanocomposites was exfoliated and high cure temperatures benefit the formation of exfoliated nanocomposites. Organoclay simultaneously improved fracture toughness, compressive modulus, yield strength and ultimate strength of the epoxy resin. Organoclay not only enhanced T g , yield strength and ultimate strength of rubber-modified epoxies, but also further improved their fracture toughness. There was a superposition effect on fracture toughness of the hybrid epoxy nanocomposites modified with both rubber and organoclay.read more

Effect of organically modified nanoclay on the miscibility, rheology, morphology and properties of epoxy/carboxyl-terminated (butadiene-co-acrylonitrile) blend
TL;DR: In this article, the effect of nanoclay on the phase behavior (UCST) of epoxy oligomer/CTBN blend has been studied in detail, and the phase diagram was shifted to a higher temperature with increase in clay loading due to the easy penetration of low molecular weight CTBN into the clay galleries.
