Interphases in Zirconium Silicate Filled High Density Polyethylene and Polypropylene (Grenslagen in Hoge Dichtheid Polyetheen en Polypropeen Gevuld met Zirconiumsilicaat)

摘要

This thesis describes the study of the replacement of yellow cadmium pigments by a zirconium silicate pigment. The main problem with the incorporation of the inorganic zircon pigment in organic polymers, like polyethylene and polypropylene, is the deterioration of the (mechanical) properties of the polymer. In general, the decline of mechanical properties is the result of the incompatibility between the two materials. Therefore it is important to modify the surface of the pigment so that it becomes compatible with the polymer. However, not all surface modifications are suitable to obtain composites with good mechanical properties. In this study the influence of different types of surface modifications on the mechanical properties has been investigated.
