本文从低分子离子的长期扩散能力和血液相容性（血小板粘附）两个方面介绍了用于透析系统的改性纳米多孔聚醚砜（PES）膜的性能。通过聚对二甲苯膜对PES膜进行表面改性，在长期扩散测试（0-28天）后显著减少了粘附于膜表面的血小板数量，而没有降低膜的扩散性能。28天后，PES膜的扩散系数降低，而聚对二甲苯涂覆的PES膜显示出一致的扩散系数值。此外，经聚对二甲苯涂覆的膜具有较少的血小板粘附在其表面上，显示涂覆膜的生物相容性和血液相容性的改善。结果表明，我们的改性PES膜具有潜在的应用于血液透析系统。
This paper presents the performance of the modified nanoporous polyethersulfone (PES) membrane for dialysis system in terms of long term diffusion capability of low molecule ions and blood compatibility (platelets adhesion). Surface modification on PES membrane by parylene film has significantly reduced the number of platelet adhered to the membrane surface after long term diffusion test (0-28 days), without degrading the diffusivity performance of the membranes. After 28 days, the diffusivity PES membrane was decreasing, whilst, the PES membranes coated by parylene have shown the consistent diffusion coefficient value. In addition, the membrane coated by parylene has less platelet adhered on its surfaces, showing the improvement of bio compatibility and blood compatibility of the coated membrane. The results indicated that our modified PES membrane has a potential use for application in hemodialysis system.
