- Membrane preparation from green chemical routes.
Example of research:
Block copolymer membranes
Higher performances and new functionalities in membrane science can be addressed by controlling the membrane morphology at a micro/nano-scale. Block copolymers with various architectures and chemical structures are self-assembled either in bulk or in solution in order to access the desired porous nanomaterials. For example, membranes with cylindrical pores, nanoparticle or “spider web” morphologies are currently under investigations (Figure 1). The nanometric organization leads to new functionalities like for example a stimuli-responsive porosity and/or surface chemistry and a self-healing behavior.
