“…One strategy to enhance the properties of polymeric membranes is to make them electrically conductive, which provides an additional mechanism for combating surface fouling 3 – 7 , inactivating viruses and bacteria 8 , 9 , and electrochemically removing heavy metal contaminants 10 . Several approaches have been explored for the production of conductive membranes, including the use of conductive polymers like polyaniline and polypyrrole 11 and the deposition of carbon nanotubes (CNT) on the surface of polymeric membranes via vacuum filtration 3 , 5 , 8 , 9 . Membranes made out of deposited CNT have been further improved by crosslinking using polyvinyl alcohol (PVA) 6 , 10 or polyaniline 12 to increase their stability.…”

Direct lasing of polymeric membranes to form laser induced graphene (LIG) offers a scalable and potentially cheaper alternative for the fabrication of electrically conductive membranes. However, the high temperatures induced during lasing can deform the substrate polymer, altering existing micro-and nanosized features that are crucial for a membrane's performance. Here, we demonstrate how sequential infiltration synthesis (SIS) of alumina, a simple solvent-free process, stabilizes polyethersulfone (PES) membranes against deformation above the polymers' glass transition temperature, enabling the formation of LIG without any changes to the membrane's underlying pore structure. These membranes are shown to have comparable sheet resistance to carbon-nanotube-composite membranes. They are electrochemically stable and maintain their permeability after lasing, demonstrating their competitive performance as electrically conductive membranes. These results demonstrate the immense versatility of SIS for modifying materials when combined with laser induced graphitization for a variety of applications.

“…As an electromembrane such as cation exchange membrane, its overall separation performance not only relies on the relative ionic affinity of the ionic species being separated to the polymer, but also relates to the current efficiency which is based on the electrical potential generated by passing given current through the membrane. 62,63 The more electronic conductive membrane materials will enhance such electrical potential. The presence of rGO in SrGO/PVDF_45 could enhance the current utilization and lead to the increased current efficiency.…”

“…The application of this technique to pressure-driven membrane processes is hindered by the inherent insulating nature of polymeric membranes. Over the years, attempts have been made to use electrically conducting polymers to form membranes for different purposes [18,19]. However, traditional conducting polymers are notoriously difficult to process, and membranes made from these materials suffer from low selectivity, low flux, and often, low conductivity [19,20].…”
