Abstract
A gas separation membrane comprising the following layers: (ii) a support layer; (ii) a discriminating layer; (iii) a further layer, wherein the further layer comprises groups of Formula (1): M-(O—)x wherein: each M independently is a metal or metalloid atom; O is an oxygen atom; and each x independently has a value of at least 4; and (iv) optionally a protective layer; wherein: (a) the support layer (i) and the further layer (iii) are on opposite sides of discriminating layer (ii); and (b) the further layer (iii) comprises 1.5 to 10 atomic % of M of Formula (1) groups, wherein M is as hereinbefore defined.
