Abstract
Compounds with strong thermodynamic affinity for carbon dioxide (CO2) have been designed and synthesized that dissolve in CO2, then associate to form gels. Upon removal of the CO2, these gels produced free-standing foams with cells with an average diameter smaller than 1 micrometer and a bulk densit y reduction of 97 percent relative to the parent material.
