Synthesis and characterization of rubbery epoxy/organoclay hectorite nanocomposites

Blog Article

The present research investigates the morphology, the mechanical, and the viscoelastic properties of rubbery epoxy/clay nanocomposites synthesized by in situ polymerisation of a prepolymer diglycidyl ether of bisphenol-A crosslinked with an Bike Parts - Derailleurs - Parts aliphatic diamine based on a polyoxypropylene backbone.The inorganic phase was hectorite, exchanged with octadecylammonium ions in order to give organophilic properties to the phyllosilicate.An ultrasonicator was used to disperse the silicate clay layer into epoxy-amine matrix.The morphology of epoxy-hectorite nanocomposites examined by transmission electron microscopy (TEM) showed that mixed delamination or intercalation or microdispersion could occur depending on type of organoclay.Moreover, the mechanical and viscoelastic Multi-board properties were found to be improved with only the treated hectorite.
