合成聚合物分离膜被广泛应用于水处理、蛋白质分离和医疗保健等领域.然而,传统聚合物膜面临着重大的挑战,例如渗透性和选择性之间相互制约、膜易被污染、机械强度低等.为了解决这些难题,本研究小组在聚合物分离膜的表/界面设计与剪裁以及膜材料构效关系上进行了系统的研究工作,并取得了以下进展:(1)提出并建立了一种基于贻贝仿生儿茶酚化学的膜表面功能化与纳滤膜制备新途径;(2)设计并制备了一种以刚性多孔基膜为载体的凝胶填充聚合物复合膜,发展了一种高机械强度的环境响应性分离膜制备方法;(3)建立了基于两亲聚合物的分离膜表面按需设计以及抗污改性的新方法;(4)设计并开发了一系列兼具过滤与吸附功能的吸附型分离膜,可用于水中痕量重金属离子、抗生素、塑化剂等微污染物的快速脱除.“,”Synthetic polymer membranes are widely used in many applications,including,among others,water purification,protein separation,and medicine.However,the use of existing polymer membranes faces major challenges,such as the trade-off between permeability and selectivity,membrane fouling,and poor mechanical strength.To address these problems the authors have focused their research on surface/interfacial tailoring and the structure-property relationship of polymer membranes used in liquid separation systems.Progress has been made as follows: (1) a methodology for membrane surface functionalization and nanofiltration (NF) membrane preparation based on mussel-inspired catecholic chemistry was proposed and established;(2) a class of mechanically robust and environmentally-responsive composite membranes with hydrogel pore-filled in rigid macroporous supports was designed and developed;(3) a methodology for surface tailoring and antifouling modification of polymer membranes based on amphiphilic copolymers was created and the scientific implications for amphiphilic polymer membranes elaborated;(4) an adsorption membrane with both filtration and adsorption functions was designed and developed to achieve rapid removal of trace micropollutants,including heavy metal ions,organic dyes,plasticizer,antibiotics,and others.This mini-review briefly summarizes this work.
