Abstract

The peculiarities of the crystal formation from supersaturated aqueous solutions of CuSO on polymer substrates were studied using X-ray diffractometry. During the crystal formation, the test solutions were irradiated with one or two counter-propagating ultrasonic beams. Test solutions were prepared using natural deionized water with a deuterium content of 157 ± 1 ppm. The other liquid used was deuterium-depleted water with a deuterium content of 3 ppm. It was shown that irradiation with one/two ultrasonic beams resulted in drastic changes in the structure of the crystal deposit formed on the polymer substrate in the case when natural deionized water was chosen for preparing the supersaturated solution of CuSO.

摘要

使用X射线衍射法研究了在聚合物基底上由硫酸铜过饱和水溶液形成晶体的特性。在晶体形成过程中，用一束或两束反向传播的超声波束照射测试溶液。测试溶液使用氘含量为157±1 ppm的天然去离子水配制。使用的另一种液体是氘含量为3 ppm的贫氘水。结果表明，当选择天然去离子水来制备硫酸铜过饱和溶液时，用一束/两束超声波束照射会导致在聚合物基底上形成的晶体沉积物的结构发生剧烈变化。
