| 摘 要： | 聚二苯基乙炔(PDPA)不溶于有机溶剂,是理想的新型耐溶剂纳滤膜材料。采用溶液浇铸法制备聚1-(4-三甲基硅基)苯基-2-苯乙炔](PTMSDPA)均质膜,经脱硅反应得到PDPA膜,研究其乙醇渗透性能和染料截留性能。结果表明,乙醇渗透通量与压力呈正相关性,传质机理可能介于孔流机理和溶解扩散机理之间的过渡区。染料的分子尺寸、电荷性质以及染料和膜之间的相互作用共同影响PDPA膜的截留性能。

| Abstract: | Poly(diphenylacetylene)(PDPA) is insoluble in organic solvents which makes it a new type promising membrane material for solvent resistant nanofiltration. PDPA membranes were obtained by desilylation of poly1-phenyl-2-p-(trimethylsilyl)phenyl]acetylene](PTMSDPA) dense membranes, which were prepared by solution-casting method. The permeation of pure ethanol and the retention of dye/ethanol solutions were investigated. The ethanol permeability of the PDPA membrane increases linearly with increased applying pressure. The transport mechanism for solvents in PDPA membrane can fall in the transition range between a pore flow and a solution diffusion mechanism. Moreover, the dye retention of the PDPA membrane is controlled by the molecular size of the dyes, the charge character and interaction between the dyes and the membrane. |
