Preparation and Characterization of Silver/Multilayer Polyelectrolyte Composite Nanofiltration Membranes

摘要

摘要: 利用层层自组装技术(LbL),采用原位还原方法在聚醚砜(PES)基膜上制备了银/聚电解质复合纳滤膜.SEM分析表明:膜表面结构致密,Ag粒子在复合膜中分布均匀,粒径100～200 nm,UV-vis图谱证明膜中粒子为Ag粒子,所得银/聚电解质纳滤膜呈现出优异的抗菌性能.PSS/PDADMAC3PAS/PAH-Ag3PSS膜对负二价离子显示出较高的截留性能,达到93%.
