| 摘 要： | 本文提出了一种研究高分子物质的吸水溶胀特性的新方法——光学干涉法。通过连续、实时地观测光在透明高分子材料中传播的光程随浸泡时间的关系,能够同时得到吸水率、溶胀率和扩散系数等主要参数及它们的时间依赖性。该方法所得结果与重量法较好的符合,但比重量法简单、灵敏、准确度高。

| Abstract: | This paper reported a new method, optical interference method, for the study of swelling ratio in transparant polymers, based on detection of the ralationship between optical path of light transmission in the polymer and the soaking time. The time dependence of equilibrium Water absorption factor, equilibrium swelling factor and diffusion coefficient can be established. These results are in agreement with those obtained by the weighting method. |
