  "textContent": "A method for preventing fuel from migrating, i.e., infiltrating, into a mircoporous polymer membrane (16), such as that used in a fuel deoxygenator device (14) of an aircraft to remove dissolved oxygen from the fuel, includes heating the membrane (16) to reduce the size of micropores (32) in the membrane (16) from a first size (38) to a second size (46) that is large enough to allow migration of oxygen through the membrane (16) and small enough to prevent migration of fuel into the membrane (16). The membrane (16) is an amorphous fluoropolymer on a PVDF substrate and the micropores (32) are reduced in size by heating the membrane (16) at a temperature between 130°C and 150°C for 2 hours.",
