Claim:
1. An in-situ process for preparation of Metallic Organic Frameworks (MOF)-polymer composite substantially devoid of pores without pre-seeding or substrate modification, comprising the steps of: a) subjecting a porous polymer membrane to solvent treatment for period in the range of 4 to 8 hr; b) repeatedly treating the membrane of step (a) with ligand solution A for period in the range of 8 to 12 hrs followed by treatment with metal solution B for period in the range of 8 to 12 hrs or vice versa; and c) repeatedly treating the membrane of step (b) with ligand solution (A) for period in the range of 8 to 12 hrs, followed by suspending the membrane in mixture of solution A and B for period in the range of 8 to 12 hrs to obtain MOF polymer composite.
