摘要
采用静态和动态激光散射测量了透明聚合物凝胶结构的空间相关性和时间相关性。结果发现 ,凝胶中含有动态相关长度不同的两种区域 ,在不同的测量点处 ,两种区域的百分比差异较大 ,从而获得了凝胶结构非均匀性的直接证据。
The space and time interference of transparent polymer gels measured by laser static and dynamic light scattering, respectively. The experimental results show that there are two areas of different dynamic interference length in gels, corresponding to the polymer-poor and polymer-rich regions. The content of the two areas was greatly changed at the different points, which provided the evidence of structural inhomogeneity in polymer gels.
