LB films of
fatty acid salts
films of fatty acid salts are deposited from aqueous subphases
containing dissolved inorganic salts of divalent metals (Ba, Cd,
Ca, Cu, Pb, and others) at a definite pH value. Salt formation
occurs between fatty acid molecules spread at the air-water
interface and metal ions. Usually, defectless uniform films can
be obtained only if mixed acid / salt monolayers are used for
the deposition. Degree of acid-into-salt conversion is pH
