Available in PDF, EPUB and Kindle. Book excerpt: Short single-walled carbon nanotubes (SWNT) functionalized with carboxylic acid groups were made and incorporated into Matrimid ® to form mixed-matrix membranes. SEM images of mixed-matrix membranes cross-sections showed good dispersion and interfacial contact. Pure gas permeation showed 100% increase in permeability compared with pure Matrimid ®, while the ideal selectivity of O2 /N2, CO2 /CH4 and H2 /N2 remained unchanged. The higher permeability can be attributed to the higher diffusivity in the SWNT.
