MIL-101(Cr)/PI纤维纸基复合材料对高温烟气过滤性能研究.

Mil-101(Cr), a metal framework compound with high specific surface area and excellent thermal stability, was synthesized by solvent thermal method. MIL-101(Cr)/PI fiber paper-based composites were made of polyimide fibers and para-aramid fibers as raw material and introducing presynthesized MIL-101(Cr)via modern wet-forming papermaking technique. The influence of content of MIL-101(Cr)on filtration performance of paper for hot gas was analyzed. The results showed that the filtration performance of paper-based composites with MIL-101(Cr)increased remarkably, the quality factor enhanced by 152. 69% and 558. 22% at room temperature and 260°C respectively.
