Special Issue Information
Dear Colleagues,
Polymers of Intrinsic Microporosity, especially PIM-1, are undoubtably a scientific success story: Peter Budd and Neil McKeown really started something in 2004, with polymeric materials with highly porous surfaces, processable and of excellent thermal stability, provided by striking but not too complicated chemical structures. A huge amount of papers have been published since then on either synthesis or possible applications. Membranes made from PIM-1 and successors were applied in gas separation, pervaporation, and nanofiltration, but then some of the flaws of the success story came to the surface: The striking material compacts rather fast and loses its initially high permeability. In the last few years, many efforts have been made to stabilize most of the striking initial properties, unfortunately with limited success. Selected examples of these attempts are cross-linkage, insertion of nanomaterials to form mixed matrix membranes, and advanced synthesis of even more contorted structures. However, the problem of PIM-membranes´ aging is still pending.
In this Special Issue, emphasis will be put on membranes of already existing PIMs, their applications to membrane processes, and the stabilization of said membranes, but also on newly synthesized PIMs with the aim of membrane application. Membranes could be in the form of thick layers, integral asymmetric structures, and thin film composites. New and unconventional ideas to form PIM materials into membranes, new applications of PIM membranes, and methods to stabilize PIM membranes are searched for and are welcomed to be presented in the Special Issue.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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.
