Special Issue Information

Dear Colleagues,

This Special Issue on ”3D Printing in Membrane Preparation and Fouling Control” is intended to bring to light the newest achievements of membrane preparation and fouling control opportunities arising from 3D printing.

Additive manufacturing (AM), colloquially 3D printing, has been expanding in many production processes and fields of life. It accelerates and drives forward the processing of goods used in various life spheres. The technology is proficient in joining various materials for creating 3D objects in plenty of shapes using 3D modeling. In additive manufacturing, objects are formed by a layer-by-layer method (LbL) as opposed to traditional manufacturing technologies. The LbL method of object formation, various types of materials used, and optimization of surface within numerous shapes display the potential of AM technologies in the preparation of membranes and membrane modules, too. The interplay of materials and shapes enabled in AM technologies is expected to accelerate membrane preparation, assist membrane fouling control, and the production of modules with a high surface to volume ratio, and new spacer and turbulence promoter geometries. Consequently, the improved efficiency of both membrane/module production and their application in processes is expected. 

As Guest Editors of the Special Issue on “3D printing in Membrane Preparation and Fouling Control”, we kindly invite you to submit research articles or critical reviews for possible publication in Membranes.

The Special Issue aims to bring the latest ideas and developments of:

  • Various membranes prepared by additive manufacturing technologies, including hybrid technologies where AM is combined with any traditional membrane preparation methods;
  • Preparation of novel membrane modules with 3D printed membrane spacers and turbulence promoters;
  • 3D printed membrane reactors, membrane-based devices used in medicine, gas separation, fuel cells, etc.;
  • The application of 3D printed membranes and modules in various membrane processes for fouling control.

Active layers of ion separation membranes often consist of charged layers that retain ions based on electrostatic repulsion. Conventional fabrication of these layers, such as polyelectrolyte deposition, can in some cases lead to excess coating to prevent defects in the active layer. This excess deposition increases the overall membrane transport resistance. The study at hand presents a manufacturing procedure for controlled polyelectrolyte complexation in and on porous supports by support wetting control. Pre-wetting of the microfiltration membrane support, or even supports with larger pore sizes, leads to ternary phase boundaries of the support, the coating solution, and the pre-wetting agent. At these phase boundaries, polyelectrolytes can be complexated to form partially freestanding selective structures bridging the pores. This polyelectrolyte complex formation control allows the production of membranes with evenly distributed polyelectrolyte layers, providing (1) fewer coating steps needed for defect-free active layers, (2) larger support diameters that can be bridged, and (3) a precise position control of the formed polyelectrolyte multilayers. We further analyze the formed structures regarding their position, composition, and diffusion dialysis performance. Full article
