Abstract:
The present invention relates to microtubes made of carbon nanotubes or composites based on carbon nanotubes. The present invention also relates to the use of such microtubes made of carbon nanotubes or composites based of carbon nanotubes as stand alone electrodes electrodes or integrated with current collectors or as a part of membrane electrode assemblies applied in electrochemical systems such as primary and secondary batteries, redox flow batteries, fuel cells, electrochemical capacitors, capacitive deionization systems, electrochemical- and biosensors devices, or solar cells. Another use of the microtubes made of carbon nanotubes or composites based on carbon nanotubes relates to their application as supported or unsupported tubular membranes for water or wastewater filtration, in aqueous and organic solvent filtration, for blood filtration, for gas separation processes, in gas and liquid adsorption processes or in sensor applications.

Abstract:
The present invention relates to a method for the preparation of a surface structured bulk hydrogel bearing a topographic and chemical pattern, comprising the steps of: (i) providing a primary master having a predetermined topographic pattern, (ii) replicating said primary master by an elastomeric secondary master to obtain a secondary master with said predetermined topographic pattern in its inverse form, (iii) replicating said secondary master by an imprintable curable material of hydrogel precursor molecules which are capable of forming a hydrogel once crosslinked by curing, and crosslinking said material to thereby yield a replica made of cross-linked bulk hydrogel bearing the topographic pattern identical to that of the primary master, and (iv) functionalizing, particularly biofunctionalizing, the bulk hydrogel replica. In particular, the method according to the present invention can further comprise the step of: - functionalizing the protrusions of the topographically structured bulk hydrogel ("inking"), - functionalizing the depressions of the topographically structured bulk hydrogel ("print-molding"), or - functionalizing the topographically structured bulk hydrogel with a chemical pattern via a metal template on either the primary or secondary master ("transfer-molding"),
to thereby specifically and locally functionalize the bulk hydrogel surface with a chemical pattern.
