ELECTROCHROMIC COMPOSITION AND METHOD OF MANUFACTURE OF DEVICE ON BASIS OF SUCH COMPOSITION Russian patent published in 2000 - IPC

FIELD: applied electrochemistry; applicable in manufacture of car rear-view mirrors, light-protective windows, panels of collective use, etc. SUBSTANCE: electrochromic composition includes at least one cathode component at least one anode component, thickening polymer and solvent. Composition is distinguished by the fact that thickening polymer is used in the form of highly dispersed polymer capable of forming suspension in electrochromic solution of the components in the following amounts, wt.%: highly dispersed polymer capable of forming suspension of electrochromic composition, 0.9-40.0; cathode component, 0.3-6.0; anode component, 0.4-1.7; solvent, the balance. EFFECT: considerably simplified method of electrochromic device manufacture, excluded preliminary formation of layer of thickening polymer on one of device electrodes. 12 cl, 11 ex
