TI  - In situ preparation of hetero-polymers/clay nanocomposites by CUAAC click chemistry
AB  - A series of polymer/clay nanocomposites containing mechanistically two different polymers, poly(ethylene glycol) (PEG) and
poly(epsilon caprolactone) (PCL), were prepared by simultaneous copper(I)-catalyzed alkyne-azide cycloaddition click reactions. Both
clickable polymers, PEG-Alkyne and PCL-Alkyne, were simultaneously clicked on to azide-functional montmorillonite $(MMTN_3)$
nanoclay to get corresponding PEG-PCL/MMT nanocomposites. The chemical structures of the resulting nanocomposites wereverified by following azide and silicone-oxygen bands using FT-IR and characteristic bands of PEG and PCL segments using $^{1}H-NMR$ spectroscopy. The combined XRD and TEM analysis confirmed that all PEG-PCL/MMT nanocomposites had partially exfoliated/ intercalated morphologies. In addition, the increase of$(MMT-N_3)$
 loading not only improved the onset and maximum degradation
temperatures of the nanocomposites but also their char yields. Furthermore, the incorporation of $MMT-N_3$
 in the polymer matrix did
not significantly influence the crystallization behavior of both PEG and PCL segments.
