Abstract: The present invention relates to a device for carrying out a capillary nanoprinting method, comprising at least one monolithic combination of a substrate (1) and one or more contact elements (2), at least parts of said contact elements (2) having a porous structure, preferably also at least parts of the substrate having a porous structure, particularly the entire monolithic combination having a porous structure.

Abstract: A three-dimensional molded body, a method for producing a three-dimensional molded body and a method for producing an adhesive bond between a polymer-containing material and a molded body having an inorganic porous framework structure in at least partial areas are described. In all cases the porous structure of the molded body comprising inorganic material is brought in contact with a polymer-containing material which is heated until the heated material enters into a joint connection with the molded body based on adhesive interactions, interfacial interactions, electrostatic interactions or any combination thereof, in which the pore-like voids of the porous structure are filled completely with the polymer-containing material, which stabilizes the molded body so that it has dimensional stability after cooling.

Abstract: The invention relates to porous fiber comprising a polymeric material, said fiber having a diameter of 20 to 4000 nm and pores in the form of channels extending at least to the core of said fiber and/or through said fiber. The process for producing the porous fiber comprises electrospinning a 5 to 20% by weight solution of at least one polymer in an organic solvent using an electric field above 105 V/m to obtain a fiber having a diameter of 20 to 4000 nm and pores in the form of channels extending at least to the core of said fiber and/or through said fiber. The porous fiber may be used as a carrier for a catalyst, as an adsorbent or absorbent or as a biomaterial, may be chemically modified or functionalized or may be used as a template for producing highly porous solids.
