摘要
研究了一系列聚芳醚的Ｈ_２／Ｎ_２透过选择性能，详细讨论了温度和结构的系列变化对气体透过性能的影响。结果表明，此系列聚合物Ｈ_２和Ｎ_２的透过系数与聚合物的自由体积间有较好的线性相关性，通过结构变化以调节聚合物的自由体积，可以有效地控制聚合物的透Ｈ_２系数和Ｈ_２／Ｎ_２选择系数。
In this paper,the permeability of five different polyarylether to H2 and N2 has been measured over a temperature range of 30℃～100℃.The effects of temperature and systematic that the polts variation on gas permeability and selectivity were discussed detaily. The results indicated that the polts of lgp vs VF gave good straight lines. The P(H2) and P(H2)/P(N2) could be controlled effectivly by adjusting the polymeric free volume.
