摘 要：The epoxy nanocomposites with similar amines(CH3（CH2）17NH2 and CH3（CH2）17N（CH3）3CI) treated montmorillonite clays have been investigated by wide-angle X-ray scattering,transmission electron microscopy（TEM）,differential scanning calorimetry（DSC） and thermal gravimetric analysis（TGA）.Different nanocomposite structures,intercalation and exfoliation were formed by the reaction of octadecyltrimethylammonium chloride-exchanged and octadecylamine-exchanged clays with epoxy resin and phenalkamine as the curing agent,respectively.Results showed that the exfoliated nanocomposite can be obtained when octadecylamine with the lower polarity was used as a modifier.However,the intercalated nanocomposite can be obtained when octadecyltrimethylammonium chloride with higher polarity was used as a modifier.
