Abstract
A method of enhancing the conductivity of silver in a silver-containing film formed on a substrate is disclosed. A silver-containing film, including silver particles and a hydrophilic binder is produced. Thereafter, the method includes exposing the silver-containing film to hot water vapor so that the binder absorbs water; drying the silver-containing film to remove water in the binder, and repeating the hot water vapor and drying steps at least one additional time to enhance the conductivity of the silver.
Claims21
A method of enhancing the conductivity of silver in a silver-containing film formed on a substrate, comprising:
- (a) providing the silver-containing film, including silver particles and a hydrophilic binder;
- (b) exposing the silver-containing film to hot water vapor so that the binder absorbs water;
- (c) drying the silver-containing film to remove water in the binder;
- and
- (d) repeating elements (b) and (c) at least one time, so as to enhance the conductivity of the silver.
A method of enhancing the conductivity of silver in a silver-containing film formed on a substrate, comprising:
- (a) providing the silver-containing film, including silver particles and a hydrophilic binder;
- (b) swelling the hydrophilic binder;
- (c) shrinking the hydrophilic binder;
- and
- (d) repeating elements (b) and (c) at least one time to work the silver particles thereby enhancing the conductivity of the silver.
A method of enhancing the conductivity of silver in a silver-containing film formed on a substrate, comprising:
- (a) providing the silver-containing film, including silver particles and a binder on the substrate;
- (b) providing a first set of stations including a first hot water vapor station for exposing the silver-containing film to hot water vapor so that the binder absorbs water, and a first drying station spaced from the hot water vapor station to dry the silver-containing film to remove water in the binder;
- and
- (c) advancing the silver-containing film on the substrate through the first set of stations in sequence through the first hot water vapor station and the first drying station.
