摘　　要：纯Ｙ型硬脂酸铅ＬＢ膜的制备及结构表征陈海燕，彭笑刚，于连香，周勇亮，姜月顺，李铁津（吉林大学化学系，长春，１３００２３）徐跃，高忠民，魏诠（吉林大学测试中心）关键词硬脂酸铅，ＬＢ膜转移，硫化铅单层膜在脂肪酸盐ＬＢ膜的沉积过程中，存在由Ｙ型向Ｘ型沉积的...The collapse pressure of lead stearate(PbSt2)monolayer on the surface of 10￣(-3)mol/L PbCl2 solution(aq) is only 36 mN/m.And higher residual PbCl2 concentration was found within the PbSt2 LB films deposited on this subphase.However,the LB films with an acceptable composition and higher collapse pressure(about 60 Nm/m) was observed in the case of a lower PBCl2 concentration(<5×10￣(-4)mol/L).Pure Y-type transfer form for PbSt_2 LB films was observed on the subphase with a lower PbCl_2 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 LB films possess a certain layer mumber which is same to the value recorded during the deposition period.
