Abstract
Official abstract text for this publication.
A composition of matter, and method to make same, for a nano-based material including a nanocarbon support to which is attached an aliphatic amine. In particular, the composition of matter is an aliphatic amine-nanocarbon material that includes a nanocarbon (NC) support, such as C 60 , nano-graphite, graphene, nanocarbon ribbons, graphite intercalation compounds, graphite oxide, nano-coal, nanohorns, and combinations thereof, and further includes an aliphatic amine, such as polyethyleneimine (PEI).
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising: a nanocarbon support, wherein the nanocarbon support is selected from the group consisting of graphite intercalation compounds, graphite oxide, and combinations thereof; and a polyethyleneimine attached to the nanocarbon support to form a polyethyleneimine-nanocarbon material. 2. The composition of claim 1 , wherein the polyethyleneimine-nanocarbon material has a CO 2 absorption capacity at ambient pressure and temperature of at least about 10 wt % of the polyethyleneimine-nanocarbon material. 3. The composition of claim 1 , wherein the polyethyleneimine-nanocarbon material has a CO 2 absorption capacity at ambient pressure and temperature of at least about 10 wt % of the polyethyleneimine-nanocarbon material. 4. The composition of claim 1 , wherein the polyethyleneimine-nanocarbon material has a CO 2 absorption capacity at ambient pressure and temperature of at least about 15 wt % of the polyethyleneimine-nanocarbon material. 5. The composition of claim 1 , wherein the polyethyleneimine-nanocarbon material has a CO 2 absorption capacity at ambient pressure and temperature of at least about 20 wt % of the polyethyleneimine-nanocarbon material. 6. The composition of claim 1 , wherein the polyethyleneimine-nanocarbon material has a CO 2 absorption capacity at ambient pressure and temperature between about 20 wt % and about 25 wt % of the polyethyleneimine-nanocarbon material. 7. The composition of claim 1 , wherein the nanocarbon support comprises graphite oxide; and the polyethyleneimine-nanocarbon material comprises a polyethyleneimine-graphite oxide material. 8. The composition of claim 1 , wherein the nanocarbon support comprises a graphite intercalation compound; and the polyethyleneimine-nanocarbon material comprises a polyethyleneimine-graphite intercalation compound material. 9. The composition of claim 1 , wherein the polyethyleneimine in the polyethyleneimine-nanocarbon material is unfolded. 10. The composition of claim 1 , wherein the ratio of (a) tertiary amines of the polyethyleneimine-nanocarbon material operable for absorbing CO 2 at ambient pressure and temperature to (b) primary amines and secondary amines of the polyethyleneimine-nanocarbon material operable for absorbing CO 2 at ambient pressure and temperature is at least about 5:1. 11. The composition of claim 10 , wherein the ratio is at least about 10:1.
