From: Nanofiber-interwoven gel membranes with tunable 3D-interconnected transport channels for efficient CO2 separation

Fig. 4

a TEM images of various NIGMs (L-NIGMs, M-NIGMs and S-NIGMs), which feature distinct configurations of CNT-interwoven skeletons made of long CNT, medium CNT and short CNT, respectively. The insets are the according schematic illustration of various CNT-interwoven skeletons: long CNT, medium CNT and short CNT. b CO2 permeance and CO2/N2 selectivity of various NIGMs (L-NIGMs, M-NIGMs and S-NIGMs) and GMs. Data presented as mean ± SD, n  =  5. c Ideal sorption selectivity and diffusion selectivity of CO2/N2 for various NIGMs (L-NIGMs, M-NIGMs and S-NIGMs) and GMs. d Schematic illustration of CO2 transport and separation mechanism through various NIGMs with distinct CNT-interwoven skeletons.
