초록

A method of producing a foamed material comprises contacting a material with a fluid mixture comprising carbon dioxide and a surfactant, wherein the surfactant facilitates the dissolution of the carbon dioxide into the material and then foam the material in the fluid mixture.

청구항

1. A method of producing a foamed material, said method comprising:contacting a material to be foamed with a fluid mixture comprising carbon dioxide and a surfactant comprising a CO2-philic segment which has affinity for carbon dioxide and a CO2-phobic segment having affinity for the material to be foamed, wherein the surfactant facilitates the dissolution of the carbon dioxide into the material to lower the interfacial tension between the carbon dioxide and the material to be foamed; and then foaming the material, wherein the material has a plurality of...
