N-halamine precursor P(ADMH-co-VAm) was used to improve thin-film-composite polyamide (PA) reverse osmosis (RO) membrane antibacterial and chlorine resistance properties through second interfacial polymerization process.The modification procedure is easy and the resultant membrane shares similar permselectivity with some commonly used RO membranes, higher than the virgin membrane;meanwhile, it demonstrates significantly improved anti-biofouling and chlorine resistance properties.P(ADMH-co-VAm) on the membrane surface plays as sacrificial layer when membrane suffers from chlorine attack, protecting the selective PA sub-layer intact.After chlorination, P(ADMH-co-VAm) transfers into N-halamine antibacterial polymer, which endows the membrane with potent antibacterial performance.

根据热力学相图定量指导膜结构形成过程,对纳微米结构的精细调控具有重要的意义.本文采用半结晶性高分子材料聚偏氟乙烯(PVDF)、有机盐烯丙基磺酸钠(SAS)和二甲基亚砜(DMSO)作为膜制备原料,首次定量绘制出PVDF/DMSO和PVDF/SAS/DMSO体系相图,并且利用相图根据溶剂蒸发诱导结晶的方法对膜结构进行预测和实验条件的设计.通过改变溶剂蒸发的时间和SAS的含量来控制溶液将达到的热力学状态
金属有机框架的结晶性导致其在粗糙表面很难避免缺陷的产生,而为了消除缺陷对分离性能的影响,其分离层厚度基本上在微米级以上,而这也导致其渗透性大大下降.因此,利用非结晶性的单宁酸/铁离子络合网络(MFN),通过层层自组装技术可以实现没有缺陷的,超薄的分离层的制备.化学组成分析测试(ATR-FTIR,XPS以及EDX)表明,随着沉积层数的增加,MFN的厚度逐渐增加.进一步分析MFN的结构得到每层MFN的

锂离子电池在高温环境下工作的安全问题受到了研究者的广泛关注.改善锂离子电池隔膜的热稳定性能够有效提升锂离子电池的安全性.使用多巴胺与聚乙烯亚胺共沉积方法对聚丙烯锂离子电池隔膜进行改性,并进一步诱导了二氧化锆纳米粒子在该隔膜表面的生成.该二氧化锆纳米粒子修饰的隔膜具有优异的热稳定性.通过二氧化锆纳米粒子修饰,聚丙烯隔膜在140℃下处理1h后的热收缩率由62.4％降低至9.4％.除此之外,隔膜的电导率

盐酸羟胺是一种重要的化工产品,在化工、医药等诸多行业均有广泛的应用.传统生产工艺普遍存在工艺复杂、成本高、后处理麻烦、收率低等问题.而酮肟水解反应是一种常见盐酸羟胺合成方法,因反应是一个热力学受限反应,反应的平衡转化率较低,所以一直没有得到应用.本课题组将肟水解反应与膜分离强化技术相结合提出肟水解反应-膜分离耦合生产盐酸羟胺的工艺路线,通过在线移除酮,提高了肟水解的转化率.针对肟水解反应液涉及较高
采用层层自组装技术制备聚电解质纳滤膜具有广阔的应用前景,但基于静电作用的聚电解质多层膜在酸碱条件下的稳定性仍有待于提高.本研究在自组装过程中引入氧化石墨烯(GO)片层作为组装材料,制备了PDDA/GO复合膜，并用于水体中染料的脱除.通过改变操作条件或对膜进行酸/碱/氧化剂预处理,考察膜的性能稳定性.通过与纯聚电解质膜进行对比,表明GO的引入能够改变膜的结构并提高其分离性能和稳定性.因此采用GO层层

苯胺废水的处理以及温室气体的控制是当今两个个重要的话题,在此引入一个新型的双极膜电渗工艺用于同时实现苯胺的去除以及温室气体二氧化碳的捕捉.首先,在电中性条件下苯胺不带电,此时利用双极膜电渗析实现了盐和苯胺的分离,脱盐率高于96.51％;然后向料液室通入二氧化碳,使得料液室中的苯胺离子化并实现二氧化碳的捕捉;最后,进行双极膜电渗析,去除了料液室的苯胺(去除率高于98.68％),并在酸室获得释放出来实
