Abstract：

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.
