血液透析膜及其材料和改性技术研究进展

Research progress on hemodialysis membranes: materials and modification technologies

  • 摘要: 慢性肾脏病(Chronic kidney disease,CKD)是全球性重大公共健康问题,严重威胁人类的生命健康。血液透析(Hemodialysis,HD)作为终末期肾病(End-Stage Renal Disease,ESRD)的主要治疗手段之一,其核心组件——血液透析膜的性能对治疗效果至关重要。本文系统综述了血液透析膜的最新研究进展,涵盖其分类、功能、材料特性、改性技术,以及新型血液透析膜的开发和商用血液透析膜的性能比较,并深入分析了现存问题,对未来发展方向进行了展望。现有血液透析膜(如聚醚砜和聚丙烯腈)在中小分子尿毒症毒素清除率、血液相容性以及膜通量等方面仍存在不足。通过调控膜结构、优化孔径分布、物理化学改性等技术,可以解决这些问题。未来,血液透析膜的发展将聚焦于生物相容性更好、功能多样化与便携化的膜材(如细菌纤维素膜、混合基质膜和微流控聚二甲基硅氧烷膜),以满足患者对高效透析和生活品质提升的需求。

     

    Abstract: Chronic kidney disease (CKD) represents a critical global public health challenge with significant implications for human morbidity and mortality. As a principal renal replacement therapy for end-stage renal disease (ESRD), hemodialysis (HD) relies fundamentally on the performance of its core component — the hemodialysis membrane. This review provides a comprehensive analysis of recent advancements in hemodialysis membrane technology, encompassing membrane classification, functional properties, material characteristics, and modification strategies. We systematically evaluate emerging membrane designs and perform comparative assessments of commercial hemodialysis membranes, while critically analyzing current limitations and proposing future research directions. Contemporary hemodialysis membranes (polyethersulfone, polyacrylonitrile, etc.) exhibit persistent challenges in three key performance parameters: clearance efficiency for small-to-medium molecular weight uremic toxins, hemocompatibility, and stable membrane flux. Current research demonstrates that these limitations could be addressed through structural modulation of membrane architecture, precise optimization of pore size distribution, and advanced surface modification techniques including chemical grafting and physical modification. Future developmental trajectories will likely focus on enhanced hemocompatibility, multifunctional integration and miniaturization of hemodialysis membranes (bacterial cellulose membrane, mixed matrix membrane, microfluidic PDMS membrane, etc.), aiming to simultaneously achieve enhanced therapeutic efficacy and improved patient compliance through portable solutions. These innovations are expected to address the growing clinical demand for high-performance dialysis systems that balance treatment efficiency with enhanced quality of life for ESRD patients.
