聚合物基疏水渗透汽化膜及其溶剂回收应用
Hydrophobic pervaporation membranes on polymer substrate for solvent recovery
摘要
Abstract
Pervaporation membranes are an emerging membrane separation technology widely used in solvent recovery and environmental protection.Through the selective permeation and vaporization process,the pervaporation membrane can effectively separate water and organic solvents,especially suitable for treating waste liquid containing aqueous solvents,which can reduce environmental pollution and realize the recycling of resources.Unlike previous reviews on pervaporation separation membranes,this paper summarizes the research progress of hydrophobic pervaporation membranes from the perspective of polymer membranes as substrates,highlighting key issues that need to be addressed to guide further development in this field.In this paper,we first discuss the challenges faced by polymer-based hydrophobic pervaporation membranes in solvent recovery and the essential requirements for practical separation applications.We outline different methods to enhance membrane hydrophobicity,such as physical blending,surface structure control and intermediate layer construction,and summarize design strategies for polymer-based hydrophobic pervaporation membranes that possess the desired microstructure and surface characteristics.Second,we introduce the broad application prospects of polymer-based hydrophobic pervaporation membranes in solvent recovery,including the recovery of solvents such as alcohols,lipids,hydrocarbons and ketones.Third,the thermal stability and pilot-scale test cases of polymer-based hydrophobic pervaporation membranes have been introduced.Finally,we analyze the challenges faced by polymer-based hydrophobic pervaporation membranes in practical applications and outlines future research and development directions.关键词
