TRIALKOXYSILANES, METHOD OF MAKING POLYETHYLENEDIOXYTHIOPHENE-BASED CATHODE PLATE HAVING SILANE UNDERLAYER AND OXIDE CAPACITOR HAVING SAID CATHODE PLATE

摘要

FIELD: chemistry.SUBSTANCE: disclosed are trialkoxysilanes of general formula I, where R-Si(OAlk)or R=-CH=N-CHCHCHSi(OAlk), R=R=-OCHCHO-, as silicon-containing additives for forming a monolayer on the surface of a tantalum anode made of pressed tantalum powder, as well as use of triethoxy-2-thienylsilane for the same purpose. Also disclosed is a method of making a cathode plate from a polymer electrolyte using the disclosed trialkoxysilanes and an oxide capacitor with a solid electrolyte, having a slug section of valve metals with a surface layer made of the disclosed trialkoxysilanes.EFFECT: capacitors with improved technical and exploitational characteristics.4 cl, 1 dwg, 3 ex
