Document Type and Number:
WIPO Patent Application WO/2013/022385
Kind Code:
A3
Abstract:
Trialkoxysilanes of general formula (I), where R1-Si(OAlk)3, R2=R3=H R2=R3=--OCH2CH2O-, R'=-Si(OAlk)3 R2=R3=--OCH2CH2O-, R1=-CH-N-CH2CH2CH2Si(OAlk)3, are proposed as silicon-containing additives for the formation of a monolayer on the surface of a tantalum anode made from compressed tantalum powder. A method for producing a cathode liner from a polymer electrolyte is described, which involves applying 8 (eight) layers of a polyethylenedioxythiophene-based polymerizing compound onto sections consisting of oxidized porous valve-metal anodes, with hardening and shaping and the subsequent washing of the sections in deionized water being carried out after every four layers, said method being characterized in that a trialkoxysilane of the general formula according to claim 1 is first applied to the sections by means of impregnating the sections with a 5% solution of, for example, triethoxy-2-thienylsilane in ethanol for 5 minutes at a temperature of 25±5°C and drying is subsequently carried out in two stages: at room temperature for 15 minutes, and in a drying oven at a temperature of 110±5°C for 15-20 minutes. An oxide capacitor with a solid electrolyte is proposed, which contains a section consisting of a porous valve-metal anode (1), on the surface of which the following are consecutively formed: an oxide layer (2) which constitutes a dielectric, a silane monolayer (3), a cathode liner produced using the method according to claim 2 and being in the form of a polyethylenedioxythiophene-based polymer coating (4), a carbon layer (5) which constitutes a cathode intermediate coating, a silver-containing layer (6) which constitutes a cathode contact layer, and a casing (7) produced, for example, by moulding a section into a plastic or by flooding the section with an epoxy compound.
