Pietsch - Klein


Christian Pietsch was born in 1984 in Naumburg/Saale (Germany) and studied chemistry at the Friedrich-Schiller-University Jena (Germany; 2003-2008) and accomplished his master thesis at the Eindhoven University of Technology (Netherlands) under the supervision of Prof. Ulrich S. Schubert. He continued as a PhD student in Jena working on stimuli-responsive copolymers as well as living radical polymerization techniques. During his PhD time, he spent two months at CSIRO (Melbourne, Australia), where he carried out research on RAFT polymerizations. Recently he submitted his PhD Thesis submitted titled as ''Design of Functional Polymer Architectures by RAFT Polymerization'' under the supervision of Prof. Ulrich S. Schubert. Since June 2013 he started a postdoctoral training with Prof. Felix Schacher working on stimuli-responsive membranes and block copolymer systems.

"Robuste Membranen aus Blockcopolymeren"

His research efforts focus on the design and characterization of new asymmetric membrane structures from amphiphilic diblock copolymers via non-solvent induced phase separation processes (NIPS). Here, the hydrophobic block acts as matrix and the hydrophilic segment forms a stimuli-responsive layer to vary e.g. the pore size.

He is also interested in membrane morphology characterization via scanning electron microscopy (SEM) and water-flux measurements. Further, he prepares novel macromolecular materials based on block copolymers, including the synthesis of novel hydrophilic/hydrophobic diblock copolymers exhibiting stimuli-responsive behavior. As synthetic tool controlled radical polymerization techniques like atom transfer radical polymerization (ATRP) and reversible addition-fragmentation chain-transfer (RAFT) polymerization are used.
