a An optical image of a mixture of 3-TBTBP precursor fine powder and NaCl crystals. b An optical image of CMT coated NaCl. c CMT/Chloroform dispersion showing a Tyndall effect. d CMT dispersions (concentration: 0.05 mg ml−1); solvent: (1) dichloromethane, (2) ethanol, (3) methanol, (4) hexane, (5) diethyl ether, (6) acetone, (7) dimethylformamide, (8) dimethyl sulfoxide, (9) tetrahydrofuran, and (10) isopropanol. e A free-standing CMT membrane with a diameter of ~47 mm prepared by filtration. f A SEM image showing the surface of a CMT membrane. g A SEM image showing the cross-section of a free-standing CMT membrane. The scale bars are 2 μm and 10 μm for f and g, respectively.
