Scholarcy highlights

  • Based on XRD and TEM results, all nanocomposites have mixed morphologies containing non-uniform intercalated layers and exfoliated single layers isolated from any stacks in the polymer matrix and improved thermal properties compared to the pure poly(2-ethyl-2-oxazoline)
  • The present study reports for the first time the preparation of poly(2-ethyl-2-oxazoline)/clay nanocomposites
  • The tosyl-functionalized montmorillonite clay is utilized as initiator for the living cationic ring-opening polymerization of 2-ethyl-2-oxazoline, which triggers the delamination of silicate layers in the polymer matrix and leading to nanocomposite formation
  • All nanocomposite samples have a mixed exfoliated/intercalated silicate layers and an improved thermal stability compared to pure poly(2-ethyl-2-oxazoline)
