Abstract
A product includes a polymer aerogel. The aerogel is physically characterized by having a transparency greater than or equal to 90% transmission of visible light through a 3 mm thickness of the aerogel. The aerogel includes at least one oligomer selected from the group consisting of: a polyamide, a polyimide, a polyacrylate, a polyvinyl, and a polythioether. A method includes dissolving at least one monomer in at least one solvent to form a mixture and causing polymerization of the at least one monomer to form at least one oligomer. The method also includes causing crosslinking of the at least one oligomer, initiating gelation of a product of the crosslinking and the at least one solvent to form an aerogel precursor; and forming an aerogel from the aerogel precursor.
Claims18
A product, comprising:
- a polymer aerogel, the aerogel being physically characterized by having a transparency greater than or equal to 90% transmission of visible light through a 3 mm thickness of the aerogel, wherein the aerogel comprises at least one oligomer selected from the group consisting of:
- a polyamide, a polyimide, a polyacrylate, a polyvinyl, and a polythioether, wherein the aerogel includes fibers, wherein an average diameter of the fibers in the aerogel is less than or equal to 10 nm.
A product comprising:
- a polymer aerogel, the aerogel being physically characterized by having a transparency greater than or equal to 90% transmission of visible light through a 3 mm thickness of the aerogel, wherein the aerogel comprises at least one oligomer selected from the group consisting of:
- a polyamide, a polyimide, a polyacrylate, a polyvinyl, and a polythioether, wherein the aerogel is characterized as having a transparency gradient along at least a portion thereof.
A product, comprising:
- a polymer aerogel, the aerogel being physically characterized by having a transparency greater than or equal to 90% transmission of visible light through a 3 mm thickness of the aerogel, wherein the aerogel comprises at least one oligomer selected from the group consisting of:
- a polyamide, a polyimide, a polyacrylate, a polyvinyl, and a polythioether, wherein the aerogel is elastic and exhibits shape memory.
