Nanodiamonds (NDs) are specific carbon nanoparticles approximately 5 nm in diameter with a large and accessible surface containing functional groups. Poly(phenylene-isophtalamide) (PA)-ND composites were prepared by solid-phase dispersal and used for dense film formation. The PA-ND composites were analyzed by Fourier transform infrared spectroscopy. The membrane structure was determined on the basis of density measurement and morphological study by atomic force microscopy. The gastransport properties were measured over a wide range of temperatures from 30 to 100 8C for the following series of penetrants: H 2 , N 2 , O 2 , and CO 2 . The experimental data of gas permeability were compared with the permeability values calculated from Maxwell's model. Data on the permeability and diffusion coefficients were used to calculate the activation energies. V C 2018 Wiley Periodicals, Inc. J.Appl. Polym. Sci. 2018, 135, 46320.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
