Ionic Liquid and Polymerized Ionic Liquids as Membranes for Clean Energy Generation and Industrial Gas Separations

Dear Colleagues,

Ionic liquids (ILs) and polymer forms of ILs have emerged as highly tuneable and versatile materials for the design of advanced gas separation membranes for CO₂ capture and other important gas separations in energy generation. The use of ILs in gas separation membranes originally took the form of supported liquid membranes (SLMs), which had high permeability and good selectivity for CO₂/N₂ and CO₂/CH₄ separation, but suffered an inability to withstand much of a pressure differential across the membrane. Poly(IL) materials and block copolymers were thus developed as a means of stabilizing ILs within a polymer matrix, resulting in greatly improved mechanical properties with some reduction in permeability while retaining good selectivity. ILs have also been used in combination with inorganic materials as mixed matrix membranes. There has been recent interest in combining ILs and high-performance polymers such as polyimides in order to overcome the limitations of early poly(IL) membranes.

This Special Issue of Membranes will focus on recent progress in the design of membranes based on ILs and poly(ILs) as well as other materials based on, or containing, ILs within their structure. Original research articles, communications and reviews are invited.

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. Membranes is an international peer-reviewed open access monthly 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 2200 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.
