Abstract
This invention is directed to a self-sealing, polyether-functional liquid electrolyte useful in an electrochromic device. The electrolyte comprises the reaction product of a polyether polyamine and a mono-epoxide hydrolyzable silane. The polyether polyamine and the mono-epoxide silane are preferably reacted in amounts so as to provide at least about 2 molecules of mono-epoxide silane per molecule of polyether polyamine.
Claims21
A self-sealing, polyether-functional liquid electrolyte which comprises an alkali metal salt incorporated into the reaction product of materials comprising:
- (i) liquid polyether diamine having two reactive amine groups and containing polyether groups, and
- (ii) liquid mono-epoxide hydrolyzable silane having at least one hydrolyzable group attached to a silicon atom.
A method for making a self-sealing polyether-functional liquid electrolyte which method comprises:
- combining materials comprising (i) liquid polyether diamine having two reactive amine groups and containing polyether groups;
- and (ii) liquid mono epoxide silane having at least one hydrolyzable group attached to a silicon atom to form a reaction mixtures;
- mixing said reaction mixture for a time sufficient to cause reaction of said epoxide groups of said mono-epoxy hydrolyzable silane with said reactive amine groups of said polyether diamine to form said polyether-functional liquid electrolyte;
- and
- incorporating an alkali metal salt into said reaction mixture.
A self-sealing, polyether-functional liquid electrolyte which comprises an alkali metal salt incorporated into the reaction product of materials comprising:
- (i) liquid polyether diamine having two primary amine groups and containing polyether groups, and
- (ii) liquid mono-epoxide hydrolyzable silane having ether linkages and three hydrolyzable groups attached to a silicon atom;
- wherein said polyether diamine and said mono-epoxide silane are reacted in amounts so as to provide at least about 2 molecules of said mono-epoxide silane per molecule of said polyether diamine.
