摘要:
以新型取代聚乙炔--聚[1-(4-三甲基硅基)苯基-2-苯乙炔](PTMSDPA)为膜材料,采用溶剂蒸发法制备均质膜,研究其对不同染料-乙醇溶液的纳滤性能。发现在所考察的压力、温度范围内,PTMSDPA均质膜的乙醇渗透性能稳定,耐压密性良好,且无老化现象。膜的分离性能不仅和染料的分子量有关,也和染料所带电荷相关,膜和染料之间的相互作用是影响膜分离性能的重要因素。
 As a novel solvent resistant nanofiltration membrane material, poly[1-phenyl-2-[p-(trimethylsilyl)phenyl]acetylene] (PTMSDPA) was used to prepare dense membranes by solution-casting method.Thenanofiltration performance of PTMSDPA membrane for different dyes-alcohol solutions was surveyed. The ethanol permeabilityof the membrane was stable under different pressures and temperatures; no compaction and aging phenomenon were observed. The separation performance of the membrane is affected by the molecular weight of the dyes as well astheir surface charge. The interaction between membrane and dye is the key factor affecting the separation performance of themembrane.
