Poreus films comprising porous inorganic materials impregnated with amine.

The present invention relates to porous films comprising (A) from 51 wt.-% to 99.9 wt.-% based on the total weight of the film of at least one porous inorganic material impregnated with at least one amine; (B) from
0.1 wt.-% to 49 wt.-% based on the total weight of the

film of at least one fibrillated fluoropolymer; and (C) 0 wt.-% to 48.9 wt.-% based on the total weight of the film of an additive component. The invention further relates to a composition for preparing such a film and its use.
