A facile polyethylenimine (PEI)-assisted dip-coating method allows crack-free films of MIL-101(Cr) and MIL-101(Cr)-NH2 to be prepared on alumina supports. The presence of PEI enhances the selectivity of the films for CO2 with respect to N2. The film surfaces can be made hydrophobic by further dip-coating with an aliphatic monocarboxylic acid.
