Crystalline Morphology and Properties of Multi-walled Carbon Nanotube Filled Isotactic Polypropylene Nanocomposites: Influence of Filler Size and Loading

Isotactic polypropylene (PP) nanocomposites with multi-walled carbon nanotubes (MWCNTs) of various diameters (10–50 nm) were fabricated by extrusion and compression-molding techniques and characterized by X-ray diffraction measurements, differential scanning calorimetry, scanning electron microscopy...
