Fluoropolymer Membranes: Some New Approaches in Preparation and Surface Modification

due to the mechanical strength and their significant chemical stability، fluoropolymers have been vastly utilized in designing and preparing separation membranes over the last decades. The most important uses include in membranous processes such as microfiltration،ultrafiltration، and membranous distillation which each one involves different mechanisms. The properties of the membranes and morphology have close relationship with flux rate، membranes'' hydrophilicity or hydrophobicity، thermal and mechanical resistance، chemical stability as well as membranes'' anti-fouling property. Today، by employing various methods in preparation and surface modification of the membranes، altering membrane properties and morphology is made possible to an acceptable extent. In this study، in addition to introducing fluoropolymers used in membrane fabrication، we discuss the main properties and structure of fluoropolymer membranes and recent advancements in the preparation and surface modification of membranes in general.
