| Ultrahigh Molecular Weight Polyethylene (UHMWPE) Micro Porous Material is made based on UHMWPE being the matrix material, by special dealing processing in moulding process, which will cause plenty of micro porous in thickness direction and fit the demand of special disposal. Since micro porous materials have been widely used in a variety of fields as functional materials, more and more polymer materials had been studied in which Ultrahigh Molecular Weight Polyethylene is focused the most due to its unique performances. But it is almost the most difficult material to process for its ultrahigh molecular, and this slows down its development.The final performances of micro porous material and its microstructure have much affection from the processing method and the manufacturing technology. In this paper, based on the research done by the formers in this area, Thermally Induced Phase Separation (TIPS) method has been chosen to produce Ultrahigh Molecular Weight Polyethylene Micro Porous Material. The reasonable manufacturing technology such as the processing parameters and the formulation of the material are studied, and Thermal Drawing method is introduced to the process.In this paper, the performances of this material have been modified in these areas as following: blending performance between SiO2, which is added as nucleant agent and intensifier, and UHMWPE, the micro morphology's modification of the material, and the Hydrophilicity of the UHMWPE. The pore diameter, diameter distribution, porosity, mechanics performance, thermal performance, and Hydrophilic performance were tested, and SEM, AFM, Optical Microscope were used to observe the morphology of micro porous material. The total performance of the micro porous material was compared. The influence of the using performance by the micro porous material processing and the microstructure were analyzed. And the relationship of the manufacturing technology, microstructure and the using performance were discussed.
