MECHANICALLY ENHANCED POROUS POLYOLEFIN COMPOSITES IN BIAXIAL DIRECTION USING FILLERS WITH HIGH ASPECT RATIO

Disclosed herein provides the porous polyolefin composites, which comprise the polyolefin polymer as the matrix and embedded fillers with high aspect ratio as the reinforcing element and are mainly featured by the enhanced mechanical properties in biaxial direction. These said composites can be used as filtering semi-permeable membranes in filtration/purification of air, water or other liquids, or can be used as separators in energy industries.
