Project Details
Project Description
Separations are crucial in the chemical and pharmaceutical industry. Membrane technology has a growing relevance as a sustainable and competitive method. Developing highly selective membranes for processes like nanofiltration, reverse osmosis and gas separation. The focus of this project is the use of new functionalized monomers nanoengineered to generate ultra-thin selective layers for membranes.
