Special Issue Information

Dear Colleagues,

Membrane processes have been widely applied in water treatment and gas separation. As organic–inorganic hybrid membranes, mixed-matrix membranes (MMMs) have the potential to maximize the advantages of both polymeric matrix and inorganic filler, and have attracted increasing interest in desalination, wastewater treatment, hydrogen separation and CO2 separation. To advance the industrial application of MMMs, scientific gaps in membrane fabrication, configuration, filler development, characterization, mechanism analysis, modeling and the exploration of MMMs in different areas should be filled. 

The purpose of this Special Issue, “Mixed-Matrix Membranes for Energy and Environmental Applications”, is to focus on recent advancements in MMMs development and application in both water treatment and gas separation. Original research articles, reviews and communications are welcome. Topics include but are not limited to: novel MMM development, structural adjustment and optimization, novel additive and filler development, upgrade of current MMM fabrication methods and separation processes, characterization techniques, transport and separation mechanisms, membrane fouling mitigation, process modelling and simulation, energy and economic analysis, and the exploration of new application areas.

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 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.

Externally selective thin film composite (TFC) hollow fiber (HF) nanofiltration membranes (NFMs) hold great industrial application prospects because of their high surface area module. However, the complicated preparation process of the membrane has hindered its mass manufacture and application. In this work, PMIA TFC HF NFMs were successfully prepared by the interfacial polymerization (IP) of piperazine (PIP) with 1,3,5-benzenetricarbonyl trichloride (TMC). The effect of the membrane preparation conditions on their separation performance was systematically investigated. The characterized results showed the successful formation of a polyamide (PA) separation layer on PMIA HF substrates by the IP process. The as-prepared HF NFMs’ performance under optimized conditions achieved the highest pure water permeability (18.20 L·m−2·h−1, 0.35 MPa) and superior salt rejection in the order: RNa2SO4 (98.30%) > RMgSO4 (94.60%) > RMgCl2 (61.48%) > RNaCl (19.24%). In addition, the as-prepared PMIA HF TFC NFMs exhibited desirable pressure resistance at various operating bars and Na2SO4 feed concentrations. Excellent separation performance of chromotrope 2B dye was also achieved. The as-prepared PMIA HF NFMs thus show great promise for printing and dyeing wastewater treatment. Full article
