Abstract
The present invention relates to a method for making shaped structures with internally coated cavities with an inside diameter in the nanometer to micrometer range and the shaped structure obtained thereby.
Claims28
A method for making a shaped structure with internally coated cavities, comprising:
- a) mixing a first material in solution with at least one second material, wherein the second material is soluble in solution or is suspended in the first material;
- b) forming the resultant mixture into template fibers with a diameter of 10 nm to 50 μm, wherein the template fibers comprise at least one coating of one or more third materials or the template fibers are embedded in at least one third material;
- c) selectively removing the first material;
- and
- d) forming an internal layer of the second material in the cavities of the third material by immobilizing the second material prior to or concomitant with step (c);
- wherein said shaped structure comprises a matrix comprising a member selected from the group consisting of inorganic compounds, metals, polymers and mixtures thereof.

A shaped structure, comprising:
- a matrix comprising a member selected from the group consisting of inorganic compounds, metals, polymers and mixtures thereof;
- said shaped structure further comprising a plurality of internally coated cavities or channels with an inside diameter of from 10 nm to 50 μm;
- wherein said shaped structure is produced by a method, comprising:
- a) mixing a first material in solution with at least one second material, wherein the second material is soluble in solution or is suspended in the first material;
- b) forming the resultant mixture into template fibers with a diameter of 10 nm to 50 μm, wherein the template fibers comprise at least one coating of one or more third materials or the template fibers are embedded in at least one third material;
- c) selectively removing the first material;
- and
- d) forming an internal layer of the second material in the cavities of the third material by immobilizing the second material prior to or concomitant with step (c).
