  • Research
    In the past decade, polymer membrane has gained high technical relevance in a wide range of applications ranging from water purification to medical applications. The importance of membrane technology is emphasized by the fact that one of the major challenges of this century is the provision of safe drinking water for a growing population. The unique properties of these discrete mass transfer interfaces arise from the physical structure and chemical functionality of the membranes and their interactions with the permeating chemical species. With the advances in polymer chemistry and materials, new membranes with improved properties can be designed for particular applications. Additionally, the use of membranes is growing in the area of catalysis and biocatalysis, where a suitable flow reactor can be constructed for continuous operations. Our research in membrane science is directed towards understanding the chemistry, structure, and surface properties of polymeric and nanostructured membranes, which controls the transport of solutes and solvents across the membranes. Based on this understanding we want to develop next generation membranes with novel properties such as responsiveness, antifouling, antibiofouling, low pressure, and ultrathin for chemical separations at the water-energy nexus, catalysis, environmental remediation, and biocatalyis
