Figure 2. CO2 flux across block-copolymer membranes.

Figure 2

(a) Experimental pH profiles in response to CO2 diffusion across three types of poly-methyloxazoline-poly-dimethylsiloxane-poly-methyloxazoline based triblock copolymer membranes. (b) Average membrane flux of CO2 (± S.E.; n = 10 each) calculated from the slope of the pH traces within 50 µm from the membrane.
