本课题的目的是分别估算肥皂膜中表面活性剂分子与内部液体分子之间的结合分子力,阐明液体薄膜破裂的机理。为此,对声速和声频在肥皂膜中的分布进行了测量。用压电聚合物检测了肥皂膜中压电陶瓷激发的表面张力波和纵波的混合声模。扫描声音的频率,利用2相锁相放大器,尝试测量声音的色散。系列频率尚未成功获得。根据得到的最低频率,估计混合模式的声速为80 m/s。
英文摘要
The aim of this theme is to estimate binding molecule forces between surfactant molecules and inner liquid molecules in a soap film separately, and clarify the mechanism of the thin liquid film break. For this aim measuring sound speed and dispersion in a soap film was undertook. Mixed sound mode of surface tension wave and longitudinal wave, stimulated by a piezo ceramic in the soap film was detected with a piezo polymer. Sweeping the frequency of the sound, and using a 2-phase lock-in amplifier, the sound dispersion was tried to be measured. Series of frequency has not yet obtained successfully. From the lowest frequency obtained the sound speed of the mixed mode is estimated to be 80 m/s.
