dc.description.abstract | Porous polymeric materials can be prepared by using micromechanical deformations. The development of porous structures in the tension of polyolefin blends are studied with the goal of developing a novel technique to make porous films. It is found in polypropylene/polyethylene copolymer blends of near 50/50 weight ratio that a metallocene polymer pair can produce stable nanopores throughout a wide range of strain, similar to50-700%. Its strain-to-break was relatively high, although its continuous phase is a brittle polypropylene. The typical size of nanopores is 10-300 nm; they start to develop at approximately 50% strain. The disruption of craze-like structures into discrete nanopores seems to be the key mechanism in stabilizing pore development. Varying stretching direction and speed controls the pore morphology.
