摘要
The epoxy nanocomposites with similar amines （CH3（CH2）17NH2 and CH3（CH2）17N（CH3）301） 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.
