摘要：

The effects of filler particle shape on the Young's and shear moduli of PP/CaCO3 and PP/Mg(OH)2 composites were studied in the concentration interval up to 50 vol/vol% filler. Calcium carbonate had irregular spherical particles and magnesium hydroxide had particles either in the form of hexagonal plates or micro-needles. Analysis based on classical models together with structural observations enabled explanation of the composition dependences of the elastic moduli. It was found that immobilization of PP matrix on the filler surface influenced the G′ and E′ moduli. The presence of the immobilized PP with increasing geometrical anisotropy of the filler particles enabled a hyperstructure in the PP/Mg (OH)2 composites.
