Polymer Membranes for High Efficient Separation

Dear Colleagues,

Polymer membranes are currently being exploited in a wide range of disciplines due to their structures and properties as well as their potential application in a wide range of separation processes. By rationally tuning the structure and surface functional groups of the membranes, the polymer membrane can be readily used to separate two phases and to extract components from one phase. For example, porous membranes act as a boundary between two phases with the ability to remove materials by a sieving mechanism based on the size of the membrane pores and the size of the matter to be removed. Non-porous membranes allow the controlled and selective transfer of one species from one phase to another, which may separate molecules based on differences in solubility or diffusivity. In addition, various polymeric and hybrid materials are used to prepare membranes that are partitions or barriers between two phases, and following the application of a driving force, they separate the phases. Properties of the membrane, such as surface charge and hydrophobicity, and process vary among polymer materials. This Special Issue of Polymers "polymer membranes for highly efficient separation" will cover recent developments in the use of polymer membrane for a wide range of applications, including separation, extraction, filtration and adsorption treatments.

Of particular interest are the synthesis and characterization of new polymer membranes that may provide highly efficient functional separation, allowing researchers to obtain desired membrane properties.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
