Abstract
A method for the production of conductive structures, wherein nanofibers are applied with a photocatalytic component onto a substrate, in particular by electrospinning, and wherein a metallic layer is deposited photolytically on the substrate.
Claims11
A process for producing metallic structures, comprising:
- a) providing nanofibers by
- providing a spinning composition comprising at least one hydrolyzable titanium compound or a condensate thereof and at least one organic polymer and/or oligomer;
- electrospinning the composition to obtain photocatalytically active composite nanofibers;
- thermal treating the photocatalytically active composite nanofibers at above 420° C. and below 480° C. to obtain photocatalytically active composite nanofibers consisting of anatase titanium dioxide crystallites in a matrix of amorphous titanium dioxide;
- and
- applying the photocatalytically active composite nanofibers to a substrate;
- b) contacting at least one precursor compound for a metallic structure with the photocatalytically active composite nanofibers;
- and
- c) reducing the at least one precursor compound to the metallic structures by action of electromagnetic radiation on the photocatalytically active composite nanofibers.
