Preparation and Characterization of Epoxy/Clay Nanocomposites
Epoxy/clay nanocomposites have been prepared using montmorillonite (MMT) ionexchanged with various organic cations ; hexadecyltributyl phosphonium ion, octadecyltrimethyl ammonium ion, methyl tallow bis-2-hydroxyethyl ammonium ion and dimethyl hydrogenatedtallow (2-ethylhexyl) ammonium ion. The resulting nanocomposites were found to show exfoliated clay structure by using transmission electron microscopy (TEM) and X-ray diffractometry (XRD). The flame retarding property of 5wt% clay/epoxy nanocomposites was found to be enhanced when compared with that of the original epoxy without clay.
