ELECTROCONDUCTIVE ADHESIVE FOR ELECTROCHROMIC DEVICES Russian patent published in 2014 - IPC G02F1/15 C09J139/06 C09J9/02 

FIELD: chemistry.

SUBSTANCE: electroconductive adhesive contains the following components in the following ratios, wt %: 20-60 polymer-oligomer complex with adhesive properties, 3-20 ion source, 20-70 solvent. The polymer-oligomer complex used is a hydrogen-bond stoichiometric complex obtained from high-molecular weight polyvinyl pyrrolidone, taken in amount of 50-80 wt %, and oligomeric polyethylene glycol telechelic, taken in amount of 20-50 wt %. A method of obtaining an electrolyte includes mixing said components in a mixer to obtain a homogeneous transparent viscous composition. The electrochromic device has two substrates with an optically transparent conducting layer between which there is an electrochromic layer in form of an oxide or polymer film, said electrolyte and a counter electrode.

EFFECT: invention enables to obtain an electrolyte which is transparent in the visible region, has high adhesive capacity to adjacent layers, electrochemical stability, considerable ion conductivity and no electron conductivity.
