Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your work to this Special Issue on “Polymer Membranes: From Synthesis to Applications”. The synthesis and applications of different polymeric membranes have attracted attention in recent decades due to their advantages, such as high separation efficiency, high selectivity, feasibility, the ability to remove metal ions, organic or inorganic colloids, bacteria or other microorganisms from water and wastewater, high flow at low pressures, fouling resistance, good mechanical, thermal, and chemical stability, and low cost.

This Special Issue will focus on the synthesis, characterization, and applications of polymer membranes. The most used polymeric membrane preparation includes phase inversion, non-solvent-induced phase separation, vapor-induced phase separation, electrospinning, track etching (swift heavy-ion irradiation, chemical etching), and sintering. The aim of this Special Issue is to open for a new preparation method for polymeric membranes. Papers on the physical and chemical structure of polymer membranes, as well as experimental and theoretical developments in this field aiming to provide a better understanding of interconnections, interactions, intermolecular and cross-linked polymeric networks, and their associated beneficial properties for various applications based on polymer membranes (e.g., electrodialysis, ultrafiltration, nanofiltration, microfiltration, osmosis, fuel cells) will be gladly considered.

In this Special Issue, original research articles, full papers, communications, and reviews are welcome. Research areas may include (but not limited to) the following:

  • Preparation of polymer membranes
  • Characterization of polymer membranes by various techniques, including FTIR-ATR, SEM, TEM, water contact angle, surface free energy, electrochemical impedance spectroscopy (EIS)
  • Polymeric membrane processes and applications (such as: membrane-based metal removal process, polymer membranes in water treatment and so on).

Technological advances in biosensing offer extraordinary opportunities to transfer technologies from a laboratory setting to clinical point-of-care applications. Recent developments in the field have focused on electrochemical and optical biosensing platforms. Unfortunately, these platforms offer relatively poor sensitivity for most of the clinically relevant targets that can be measured on the skin. In addition, the non-specific adsorption of biomolecules (biofouling) has proven to be a limiting factor compromising the longevity and performance of these detection systems. Research from our laboratory seeks to capitalize on analyte selective properties of biomaterials to achieve enhanced analyte adsorption, enrichment, and detection. Our goal is to develop a functional membrane integrated into a microfluidic sampling interface and an electrochemical sensing unit. The membrane was manufactured from a blend of Polycaprolactone (PCL) and Polyethylene oxide (PEO) through a solvent casting evaporation method. A microfluidic flow cell was developed with a micropore array that allows liquid to exit from all pores simultaneously, thereby imitating human perspiration. The electrochemical sensing unit consisted of planar gold electrodes for the monitoring of nonspecific adsorption of proteins utilizing Cyclic Voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS). The solvent casting evaporation technique proved to be an effective method to produce membranes with the desired physical properties (surface properties and wettability profile) and a highly porous and interconnected structure. Permeability data from the membrane sandwiched in the flow cell showed excellent permeation and media transfer efficiency with uniform pore activation for both active and passive sweat rates. Biofouling experiments exhibited a decrease in the extent of biofouling of electrodes protected with the PCL/PEO membrane, corroborating the capacity of our material to mitigate the effects of biofouling.
