Special Issue Information

Dear Colleagues,

On behalf of the organizing committee of the PERMEA, we are pleased to invite you to the International Scientific Conference PERMEA 2019 (26–29 August 2019, Budapest, Hungary), the Membrane Science and Technology Conference of Visegrád Countries, organized by the Hungarian Chemical Society. More information about PERMEA 2019 can be found at:

PERMEA 2019 brings together experts from the areas of research and application and offers many opportunities to exchange experience, create new ideas, mainly thanks to the presence of young colleagues and students. Moreover, the conference presents an opportunity for a connection between industrial and academic spheres, establishing a platform where industry meets science. The PERMEA 2019 conference will focus on the following topics:

  • environmental protection with membranes
  • membrane development (fabrication and technology)
  • drinking and wastewater treatment
  • modeling
  • membrane reactors
  • gas/vapor separation
  • electromembrane processes
  • emerging technologies

Participants of the conference are cordially invited to contribute original research papers or reviews to this Special Issue of Membranes. A 50% discount (CHF 500) on the article processing charges is available for all the attendees of PERMEA 2019.

Prof. Nándor Nemestóthy
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at 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 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.

A series of microfiltration membranes were fabricated by the extraction of polyisobutylene (PIB) from its immiscible blends with polymethylpentene (PMP). Three PIB with different molecular weight of 7.5 × 104 (Oppanol B15), 34 × 104 (Oppanol B50) and 110 × 104 (Oppanol B100) g/mol, respectively, were used to evaluate the effect of molecular weight on the porous structure and transport properties of resulting PMP-based membranes. To mimic the conditions of 3D printing, the flat-sheet membranes were fabricated by means of melting of mixtures of various PMP and PIB concentrations through the hot rolls at 240 C followed by a quick cooling. The rheology study of individual components and blends at 240 C revealed that PIB B50 possessed the most close flow curve to the pure PMP, and their blends demonstrated the lowest viscosity comparing to the compositions made of PIB with other molecular weights (B15 or B100). SEM images of the cross-section PMP membranes after PIB extraction (PMP/PIB = 55/45) showed that the use of PIB B50 allowed obtaining the sponge-like porous structure, whereas the slit-shaped pores were found in the case of PIB B15 and PIB B100. Additionally, PMP/B50 blends demonstrated the optimum combinations of mechanical properties (str = 9.1 MPa, E = 0.20 GPa), adhesion to steel (adh = 0.8 kPa) and retention performance (R240 nm = 99%, R38 nm = 39%). The resulting membranes were non- or low-permeable for water if the concentration of PIB B50 in the initial blends was 40 wt.% or lower. The optimal filtration performance was observed in the case of PMP/B50 blends with a ratio of 55/45 (Pwater = 1.9 kg/m2hbar, R240 nm = 99%, R38 nm = 39%) and 50/50 (Pwater = 1100 kg/m2hbar, R240 nm = 91%, R38 nm = 36%).
