Abstract
A product includes an aerogel having a single bulk structure, the single bulk structure having at least one dimension greater than 10 millimeters. The single bulk structure includes a plurality of pores, where each pore has a largest diameter defined as a greatest distance between pore walls of the respective pore. In addition, an average of the largest diameters of a majority of the pores is within a specified range, and the plurality of pores are distributed substantially homogenously throughout the single bulk structure.
Claims15
A method of forming a single bulk aerogel having a linear dimension greater than 10 millimeters and having a homogenous distribution of pores throughout, the method comprising:
- mixing a solution comprising resorcinol and formaldehyde, wherein the solution has a volume greater than 100 milliliters;
- heating the solution to a first temperature for a first defined duration of time;
- cooling the solution to a second temperature lower than the first temperature;
- and
- curing the solution for gelation of the solution,
- wherein the curing occurs at about the second temperature for a second defined duration of time.
