Latest Patents
Hitoshi Kunimi holds a patent for a method of electrodepositing a hexacyano-cobalt iron complex. This method involves the general formula Fe.sub.x [Co(CN).sub.6 ].sub.y, where 3 ≤ x ≤ 4 and 2 ≤ y ≤ 3. The electrochromic material developed through this method exhibits high memory effects and quick response times. The process involves electrodepositing a film from an aqueous mixed solution of K.sub.3 [Co(CN).sub.6 ] and an iron(III) salt, such as FeCl.sub.3. The electrolytic reduction process is carefully controlled by periodically adjusting the cathode potential, which can be varied in a saw-tooth wave, rectangular wave, or sinusoidal wave pattern. This technique results in a uniform electrochromic film with consistent physical properties and color tones.
