Electrochromic devices based on electrochromic iridium oxide electrodes are disclosed. These electrodes are iridium oxide entities produced by vacuum deposition techniques such as by sputtering from an iridium target in the presence of an oxygen atmosphere. All solid state electrochromic devices utilizing such electrodes are possible.

A method for electroless plating relatively inert plastics, e. g. , polyvinylidene fluoride, with metal, such as gold, copper or nickel has been developed. The process requires that the plastic be treated with a solvent such as n,n-dimethylformamide or dimethylsulfoxide. The plastic is then sensitized with silver followed by treatment with a suitable activator for the electroless plated solution. Continuous adherent thin films of the desired metal coating are produced.

Electrochromic devices utilizing an electrochromic iridium oxide electrode and a tantalum oxide counterelectrode exhibit a voltage threshold and short circuit memory. The short circuit memory and voltage threshold allow the use of these devices in matrix addressing schemes.

It is possible to significantly increase the efficiency of the electrolysis of water into hydrogen and oxygen while maintaining stability of the anode. This efficiency increase is obtained by using an iridium oxide anode which is produced by vacuum deposition techniques.
