报告简介：

    Membrane technology has emerged as an important separation process for H₂ purification and CO₂ capture.  Conventional membrane material designs are often focused on rigid polymers with strong size sieving ability to enhance diffusivity selectivity.  In contrast, our research focuses on the exploration of specific interactions between the penetrant and membrane materials to achieve high solubility selectivity and thus high separation performance.  In this presentation, I will describe the design of mixed matrix materials (MMMs) containing palladium (Pd) nanoparticles, which have a strong affinity towards H₂ and thus extremely high H₂/CO₂ solubility selectivity at 50 - 200 ^oC.  The increase of Pd loading in polymers can increase the H₂/CO₂ selectivity by as much as 250%.  I will also describe the design and synthesis of highly polar polymers containing ether oxygens with a strong affinity toward CO₂ for CO₂/N₂ separation. These polymers are prepared from 1,3-dioxolane and contain higher ether oxygen content than poly(ethylene oxide) (PEO), and thus they exhibit more superior CO₂/N₂ separation properties than PEO-based membrane materials. The relationship between polymer structure and gas transport properties will be discussed in this presentation.
