摘要:

聚合物膜是膜分離過程的核心基礎材料，在解決水資源、能源、環境、健康等領域的重大問題中發揮著不可替代的作用。傳統的聚合物膜材料存在孔徑分布寬、通量小、易污染等共性難題，難以實現低能耗下的高效分離。近年來，本研究小組從膜材料的微結構設計出發，致力于探尋實現膜材料高性能化與多功能化的新思路和新原理，建立和發展了一系列膜材料制備與改性的新方法，優化了聚合物膜材料的孔徑/孔徑分布、親/疏水性、荷電特征等結構特征，顯著提升了膜材料的通量、分離精度和抗污染能力。本文從膜材料的制備與改性兩個方面入手，介紹了近年來聚合物膜材料制備與結構調控方面的研究進展，為分離膜材料的研究提供參考。

Abstract:

Membrane technology has been widely applied in the solution of some great issues that humans are facing in water resource, energy resource, environment, and heath etc. Polymer membranes play a key role in membrane separation processes, in which high efficiency separation with low energy consumption is desirable. Traditional polymer membranes are often subject to some challenges such as wide pore size distribution, low permeability, membrane fouling. To address these problems, in the past decades, many efforts have been made on the preparation and structure control of polymer membranes. The objective of these work is to achieve the high performance and multifunctionalization for membrane materials from the design and control of membrame microstructure. By the optimization of pore size distribution, hydrophilicity/hydrophobicity and charge characteristic etc., we have developed a series of novel membrane materials with enhanced permeability, separation accuracy and antifouling ability. In this paper, recent research progresses on the preparation and modification of polymer membranes used in water treatment are reviewed. The development and study prospective of water treatment membranes are proposed. This review may be helpful for researchers whose interests focus on polymer membranes for water treatment.
