Porous polypropylene membranes were coated with plasma polymerized titanium isopropoxide in a 75 kHz plasma reactor. It was noted that the presence of air in the plasma chamber in the amount of deposited polymer. Selection of the process parameters enabled obtaining membranes with up to 300 mu g cm(-2) of polymerized titanium isopropoxide. Deposition of the titanium oxide layer resulted in the reduction of permeate flux but it significantly improved the membrane photocleaning ability The recovery index reached the level of 95 % for membranes with the highest amount of the titanium oxide deposit.
