Preparation and Properties of Phenolic Resin/Montmorillonite Intercalation Nanocomposites

摘要

Phenolic resin/montmorillonite intercalation composites were prepared by using the methods of pressing intercalation and melt intercalation. Properties and structure of the composites were investigated by using XRD, TG and test of softening point. It is indicated that both the pressing intercalation and melt intercalation can be used to prepare the phenolic resin/organo-montmorillonite intercalation nanocomposites. Compared with phenolic resin, the intercalation nanocomposites have better heat-resistance, higher decomposition temperatures and less thermal weight-loss. However, these two intercalation methods have different effects on the softening point of the intercalation nanocomposites. Pressing intercalation almost does not affect the softening point of the intercalation nanocomposites, while melt intercalation significantly increases the softening point of the intercalation nanocomposites, probably due to the chemical actions happening in the process of melt intercalation.
