| Research Abstract |
In this study, we successfully prepared the nanowrinkled PE membranes with network of 30nm-thickness homogeneous lamellae using a novel entanglement control technique composed of biaxial melt-drawing and melt-shrinking procedures, which were limited for highly entangled ultra-high molecular weight materials. Such a network arrangement of nanowrinkled lamellae spreading not only on membrane surface but also across membrane thickness improves the mechanical properties of both tensile strength and tearing strength. Subsequent cold-drawing causes delamination of the lamellar interfaces, leading to the resultant nanoporous morphology composed of passing-through channels several tens of nanometers in diameter without any solvent processing.
