Porous PEEK membranes with controlled pore size in the range of 5 to 500 nm were prepared. The methodology allows for preparation of porous materials with a high pore volume and very high surface area. Porous membranes with a surface area as high as 250 m 2 /g were prepared as measured by nitrogen adsorption BET. Hollow fiber membranes with broad range of dimensions ranging from 250 nm to 2 mm in diameter were prepared and showed stable filtration performance in a broad range of solvents including chlorinated hydrocarbons, aprotic solvents, aromatic solvents, alcohols and ketones. Surface functionalization was utilized to further tailor membrane characteristics towards target separation application. Hydrophilic PEEK membranes were prepared by modifying porous PEEK membrane surface with hydroxyl groups (~OH) through selective ketone group reduction or by grafting hydroxyl group containing molecules to porous PEEK membrane surface through imine group formation. This methodology allows for preparation of hydrophilic membranes with the surface energy as high as 65 dyne/cm. Highly hydrophobic porous membranes are prepared by grafting porous PEEK membrane surface with perfluorohydrocarbons. Porous membranes with very low surface energy that do not wet by alcohols can be prepared. Porous PEEK hollow fibers can serve as an ideal substrate for preparation of composite membranes. Nanofiltration membranes and gas separation membranes can be prepared by depositing a surface separation layer by solution coating or by surface grafting. PEEK based nanofiltration membranes with molecular weight cut-off of 2000 Dalton capable of stable operation in solvents was prepared. Composite gas separation membranes capable of high temperature operation were also prepared. Stable continuous operation in air for more than 500 hours at 200 ºC was demonstrated.

Phan, University Aix-Marseille, France D. Gigmes, University Aix-Marseille, France D. Bertin, University Aix-Marseille, France Block copolymers enable well-defined micro- and nano-structure design thanks to their excellent properties to self-assemble. This building bricks can be used in Membrane Science in order to control membrane morphology. It is assumed that heterogeneous structure (high polydispersity of the pore size) could be reorganized in homogeneous structure by using block copolymers. In this contribution, our last results in this field will be discussed, showing that block copolymers, pure or in blend, can help in the production of membrane with controlled architecture and interfacial properties.
