Abstract
Embodiments of the present invention describe a method for manufacture of a gel material comprising the steps of: forming a gel sheet by dispensing a gel precursor mixture; allowing gelation to occur to the gel precursor mixture; and cooling the formed gel with a cooling system to control reaction rate.
Claims26
A method for manufacture of a gel material comprising:
- (a) forming a gel sheet with thickness of at least about 0.5 mm by dispensing a gel precursor mixture at first temperature, and allowing gelation of a gel precursor of the gel precursor mixture to occur;
- and
- (b) cooling at least one surface of the gel sheet at a second temperature with at least one cooling system, wherein the second temperature is cooler than the first temperature, wherein the cooling reduces a rate of a solvent evaporation.
A method for manufacture of a fiber-reinforced gel material comprising:
- (a) forming a fiber-reinforced gel sheet with thickness of at least about 0.5 mm by combining a fibrous structure and a gel precursor mixture at a first temperature, and allowing gelation of a gel precursor of the gel precursor mixture to occur;
- and
- (b) cooling at least one surface of the fiber-reinforced gel sheet at a second temperature with at least one cooling system, wherein the second temperature is cooler than the first temperature, and wherein the cooling reduces a rate of a solvent evaporation.
