Abstract

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.
