AB  - This work is made to ascertain the effects of mineral fillers, namely calcium 
      carbonate and talc, on the morphology and properties of multilayer polypropylene 
      (PP)/high-density polyethylene (HDPE) porous membranes. Multilayer membranes were 
      prepared using the three-stage Melt-Extrusion, Annealing and Uniaxial Stretching 
      (MEAUS) process. The orientation of PP's crystalline phase was affected by both 
      the flow-induced crystallization and the heterogeneous nucleation promoted by the 
      fillers. A synergistic effect was observed in the filled samples due to the 
      generation of pores after the stretching-induced lamellae separation and the 
      debonding of mineral fillers from the polymeric matrix. The fillers increased the 
      porous surface, leading to an increase of permeance to air, being this effect 
      more marked at higher filler contents. Talc showed a higher efficiency to create 
      porous surfaces when compared to calcium carbonate. The thermal stability of the 
      membranes increased with filler addition, as well as their stiffness and 
      strength.
