Application of a redox polymer of the poly Me(R Salen) type onto a conducting substrate is accomplished by the method of electrochemical polymerization. Said polymerization is accomplished by supplying a voltage between the substrate (that serves as an anode) and a counter electrode (that serves as a cathode), with both of them being submerged into the electrolyte containing an organic solvent and the compounds capable of dissolving in said solvent. The process is accompanied by the production of electrochemically inactive (at concentrations of no less than 0.01 mol/l) ions within the range of potentials from -3.0 V to +1.5 V, and metal complex Me(R Salen) dissolved at a …

Why it's free to use
- Filed September 15, 2003 and granted April 23, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 15, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 15, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
