  4. Abstract:
  5. A study was conducted to report an observation on the effect of nanoclay fillers on the α-relaxation in an epoxy resin. The observation provided useful facts about glass transition processes in nanoclay-filled epoxy composites. The investigation involved the synthesis of intercalated-exfoliated clay-epoxy compounds, by swelling an organophilic montmorillonite in an aromatic epoxy resin and polymerization. The epoxy resin used in the study was a diglycidyl ether of bisphenol A (DGEBA), EPON 828, with an equivalent weight of 184-190 g/eq from Hexion Specialty Chemicals. The epoxy resin was cured with piperidine, obtained from Sigma-Aldrich. Nanomer® 1.30E. An octadecyl amine treated montmorillonite fromNanocor was chosen as the nanofiller, to conduct investigations in the study
