Abstract
The present invention relates to a composition for an electrochromic device having improved optical transmission and elasticity, and a manufacturing method of an electrochromic member, wherein the composition for an electrochromic device according to an embodiment of the present invention includes a light-transmitting polymer resin, a plasticizer, and an electrochromic material.
Claims11
A composition for an electrochromic device comprising:
- a light-transmitting polymer resin;
- a plasticizer;
- and
- an electrochromic material,
- wherein the electrochromic material is selected from a group consisting of diheptyl viologen dihexafluorophosphate and ethyl viologen dibis(trifluoromethanesulfonyl)imide, wherein,
- when the electrochromic material is diheptyl viologen dihexafluorophosphate, the electrochromic material is contained in an amount of 14 to 17 parts by weight per 100 parts by weight of the light-transmitting polymer resin, and
- when the electrochromic material is ethyl viologen dibis(trifluoromethanesulfonyl)imide, the electrochromic material is contained in an amount of 11 to 14 parts by weight per 100 parts by weight of the light-transmitting polymer resin.
