Abstract

Calcium carbonate in micron size was opted for the fabrication of microporous membranes based on polypropylene through the MEAUS approach (melt extrusion-annealing-uniaxial stretching) and a twin-screw extruder. Polypropylene was blended with different amounts of fillers (1, 5, 10% by weight calcium carbonate). Various techniques were employed to examine the effects of the fillers. The crystal orientation was analyzed using polarized infrared spectroscopy (FTIR), while differential scanning calorimetry (DSC) was used to investigate crystal properties. The thermal stability of the membrane was evaluated using thermogravimetric analysis (TGA). Tensile testing was done to determine the rigidity and ductility of the produced types. The use of mineral fillers resulted in an enhanced pore distribution across the surface of the membrane. The mechanical results suggested that the formation of micropores is likely to occur more easily in the amorphous phase, as annealing leads to the perfection of lamellae and the reduction of molecular chain entanglements in the amorphous phase.
