Development and characterization of mineral-filled (calcium carbonate or talc) polypropylene porous membranes obtained by extrusion

Habibi, Kian (Date of defense: 2019-06-04)

One of the techniques to make porous membranes from polymers is based on the stretching a polymer film containing a row-nucleated !amellar structure.This special crystalline structure may be achieved ...

Development of mono and multilayer membranes of polypropylene and ethylene-propylene copolymers via cast film extrusion and stretching

Castejón Galán, María del Pilar (Date of defense: 2020-12-17)

This dissertation investigates the three-stage method MEAUS (melt-extrusion, annealing, and uniaxial stretching) for producing microporous membranes. This method for membrane preparation is a solvent-free ...
