ABSTRACT:  Polymeric porous composites consisting of polypropylene (PP) and polyethylene (PE) powder were prepared by continuous extrusion sintering method for use in air purification systems. SEM analysis showed that a composite polymeric porous structure made up of PP and PE was obtained. The morphologies consisted of PE melted and adhering to PP domains due to the lower melting temperature of PE than that of PP. The filtrating characteristics and mechanical properties of polymeric porous composite materials were investigated with variation in head die temperature of extruder, extrusion velocity, and the content and melt index of PE. The filtration efficiency increased with PE. However it increased by increasing the melt index of PE. The developed polymeric porous composites composed of PP and PE was suitable as the filtering element of air purification systems.
