This review covers recent progresses made in pervaporation (PV). The performances of polymer and inorganic (zeolite and silica) membranes and organic–inorganic composite membranes are summarized according to different applications such as ethanol (EtOH) dehydration and the separation of organic–organic mixtures. The preparation methods and morphologies of different types of membranes are discussed. The transportation mechanism also is discussed based on solution‐diffusion and pore‐flow models.

Development in the area of glycosylated membranes has been actively pursued in the past few years. This kind of promising biomimetic material is inspired by cell membranes. The recent surge of interest in these glycosylated membranes stems from their widespread number of applications to many areas in science and technology. With the glycosylation strategy, membrane separation properties, such as flux and antifouling, are greatly improved. Moreover, the ability to modulate biocompatibility, protein recognition, separation of biomolecules, enzyme immobilization, cell culture, and microorganisms capture are important in a variety of biological and medical applications. This review focuses on the recent progress in the preparation of these glycosylated membranes and highlights their applications.
Microbial polysaccharides are characterized by high molecular structure variability which translates into a wide range of different properties offering interesting opportunities for application in many different areas, including membrane-based products and processes. Due to their new or improved properties, microbial polysaccharides can replace plant, algae, and animal products, either in their traditional or in new applications. The main constraint to their wider use is the production costs that are still higher than that of other natural and synthetic polymers. The current applications of microbial polysaccharide membranes in medical, food, and industrial processes are outlined. The limitations still faced by these membranes and the requirements for obtaining innovative products and processes are also addressed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
