"Pushing the limits of polymer functionalization and transport"

Rendez-vous le 1er juillet à l'UFR de chimie tour 32 salle 101

Nanoscale pores and their ionic transport characteristics have a strong impact on various technologies from oil production, separation and sensing, to drug delivery, catalysis and energy conversion. Technological nanopores have been demonstrated to gate transport using responsive polymers. The performance of natural pores and channels goes far beyond transport gating, demonstrating directed, highly selective, and gated transport. One key factor for this performance is their nanoscale structure and functional group arrangement. Fascinated by this performance and nanoscale precision we aim to advance control and precision of polymer functionalization and with this transport performance of technological pores. Making such materials available by automated fabrication we are as well interested in developing strategies for polymer functionalization which are compatible with technologies such as printing and light-based polymer writing.

More specifically, this talk will highlight our recent advances in polymerization control and re-initiation of polymerization to graft block co-oligomers in silica mesopores mainly focusing on iniferter-initiated RAFT polymerizations. Furthermore, visible-light- and surface plasmon induced nanopore polymer functionalization for polymer writing as well as placement of different functional units into inverse opal monolayers will be presented. Finally, integration of dense and mesoporous silica into strongly hierarchical natural materials such as paper and resulting fluid transport control will be discussed paving the way to understand the role of nanopores in hierarchical material properties and on fluid imbibition in such materials.
