Chemical Engineering Graduate Seminar
Speaker: Dr. Wojciech Ogieglo, Research Scientist, King Abdullah University of Science and Technology.
Polyimides of intrinsic microporosity (PIM-PIs) are a subclass of polymers of intrinsic microporosity (PIMs) which can serve as excellent precursors for high-efficiency carbon membranes for molecular separations. Such membranes can be used in a variety of applications such as natural gas processing, air separation, or hydrogen purification. Exposure to temperatures above 400 °C under an inert atmosphere leads to profound chemical and morphological transformation of the organic polymer precursor into amorphous, microporous carbon molecular sieve (CMS) structures.
In this talk, I will present how a thorough understanding of those complex reactions can lead to a design of precisely molecularly sieving membranes. Next to excellent separation properties, these membranes show promising scale-up potential as they build on common processing techniques used in the membrane fabrication industry today.
Wojciech Ogieglo has been Research Scientist in the group of Prof. Ingo Pinnau at King Abdullah University of Science and Technology in the Kingdom of Saudi Arabia since 2017. He received his Ph.D. degree (cum laude) from the University of Twente in the Netherlands in 2014 followed by two postdoctoral fellowships at the University of Twente and DWI Leibniz Institute for Interactive Materials in Germany. He has co-authored over 50 peer-reviewed articles in the field of chemical engineering, the physics of thin polymer films, and membrane science and technology. His current research activities deal with thin and ultra-thin composite membranes comprising amorphous microporous materials, such as polymers of intrinsic microporosity and carbon molecular sieves.
