Influence of Compatibilizer and Processing Conditions on the Dispersion of Nanoclay in a Fiber-Forming Polypropylene Matrix

Abstract
Polypropylene (PP)/Montmorillonite (MMT) nanoclay based composite was prepared by melt compounding with maleic anhydride grafted polypropylene (MA-g-PP) in a twin screw extruder and an internal mixer. Test specimens were prepared by compression molding. Mechanical properties such as tensile modulus, tensile strength and maximum percent strain were measured. The clay dispersion was investigated using wide angle X-ray diffraction and scanning electron microscopy. The XRD patterns and SEM images show that introducing the proper compatibilizing agent ratio and
suitable processing condition like a twin screw extruder decrease the immiscible clay component in the matrix. However, the increase of tensile strength is not achieved. Keywords: polypropylene, montmorilloinite, nanoclay, dispersion, processing conditions.
