Abstract: The collapse pressure of lead stearate(PbSt₂)monolayer on the surface of 10^-3mol/L PbCl₂ solution(aq) is only 36 mN/m.And higher residual PbCl₂ concentration was found within the PbSt₂ LBfilms deposited on this subphase.However,the LBfilms with an acceptable composition and higher collapse pressure(about 60 Nm/m) was observed in the case of a lower PBCl₂ concentration(<5×10^-4mol/L).Pure Y-type transfer form for PbSt₂ LBfilms was observed on the subphase with a lower PbCl₂ concentration by the use of a faster dipping speed(10 cm/min).By X-ray diffraction measurements,it was determined that the pure Y-type PbSt₂ LBfilms possess a certain layer mumber which is same to the value recorded during the deposition period.

Key words: Lead stearate, Transter of LB films, Lead sulfide monolayer
