Abstract
Official abstract text for this publication.
A gas separation membrane, a method for making the gas separation membrane, and a method for using the gas separation membrane are provided. An exemplary gas separation membrane includes a polyether-block-polyamide (PEBA) matrix and a cross-linked network including functionalized polyhedral oligomeric silsesquioxane (POSS) nanoparticles dispersed through the PEBA matrix.
First claim
Opening claim text (preview).
What is claimed is: 1. A gas separation membrane, comprising: a polyether-block-polyamide (PEBA) matrix; and a cross-linked network comprising functionalized polyhedral oligomeric silsesquioxane (POSS) nanoparticles dispersed through the PEBA matrix. 2. The gas separation membrane of claim 1 , wherein the functionalized POSS nanoparticles comprise functional organic substituents at each of eight vertices. 3. The gas separation membrane of claim 2 , wherein the functional organic substituents comprise acrylate groups. 4. The gas separation membrane of claim 2 , wherein the functional organic substituents comprise methacrylate groups. 5. The gas separation membrane of claim 1 , wherein the cross-linked network comprises polyacrylate chains between the functionalized POSS nanoparticles. 6. The gas separation membrane of claim 1 , wherein the cross-linked network comprises polymethacrylate chains between the functionalized POSS nanoparticles. 7. The gas separation membrane of claim 1 , wherein the gas separation membrane comprises functionalized POSS nanoparticles at between about 2.5 weight percent (wt. %) and about 50 wt. % of the weight of the PEBA. 8. The gas separation membrane of claim 1 , wherein the gas separation membrane comprises functionalized POSS nanoparticles at between about 10 wt. % and about 40 wt. % of the weight of the PEBA. 9. The gas separation membrane of claim 1 , comprising a free radical photoinitiator to form the cross-linked network.
