摘要: A thermodynamic model was used to predict the morphology of hybrid multicomponent polymer blend systems. Two systems were studied, both including two noncompatible polymers, a third compatibilizer and layered, organo-treated clays. The polar nonpolar contributions surface energies components calculated using measurements contact angles. relative position organo-clays within them, predicted by calculating interaction between different system evaluating these values according Vaia Giannelis for melt intercalation in organically modified layered silicates. experimental results show good correlation with prediction that will have higher affinity component situated at interface components. In addition, presence this found significant additional compatibilizing effect phases. presented work support idea formation via depends mostly on energetic factors can be determined from polymers organo-modified silicates, also case multiphase system.
