초록

본 실험에서는 분자량이 다른 4개의 polyethylene oxide(PO)물 2성분용액의 음속을 초음파 pulse의 다중반사에 의한 수 MHz의 주파수영역에서 측정하였다. PO/물 2성분용액의 음속과 점성도를 각각 pulse-Echo-Overlap방법과 Oswald점도계를 사용하여 25℃∼60℃의 온도구간과, 1wt%∼3wt%의 농도구간에서 온도와 농도를 각각 변화시키면서 대기압하에서 측정하였다. 용액의 음속은 온도와 농도가 증가함에 따라 증가함을 알 수 있었는데 이는 일반적으로 농도증가에 따른 compressibility의 감소 때문인 것으로 생각된다. 온도와 농도에 따를 점성도는 일반적인 결과를 나타냄을 알수 있었으며, PO의 분자량에 따른 음속의 변화는 분명하게 알 수 있었다.

In this stu요 the sonic velotities of four po1yethylene oxide(PO)/water binary solutions were measured weight of PO, by the method of multireflection of ultrasonic pulses in a few MHz frequency ranges. The sonic velocities and viscosities of the solutons were measured at the temperature ranges of 25℃∼60℃ and at the concentration ranges of 1 wt%∼3 wt% by a pulseecho-overlap method and by an Oswald viscometer, respectively. It is found that the sonic velocities of the solutions increase as the temperatures and the concentrations increase in general
