摘要

以作者近年来对强电解质凝胶的研究结果为中心，介绍了磺酸基凝胶和丙烯酸基凝胶在纯水、缓冲溶液中溶胀比与电荷密度的关系及其差异，揭示了磺酸基凝胶中的反离子凝聚现象和在有机溶剂中的体积相变，还讨论了体积相变的滞后现象及其成因，最后就体积相变的驱动力、统一认识聚电解质和离聚体以及有关的实验结果阐述了作者的见解。

Abstract

Swelling behavior depending on the charge density of sulfonic acid gels and acrylic acid gels in water and buffers was reviewed on the author’s results.The counterion condensation in the sulfonate gels and their volume phase transition were summarized here

showing the hystersis during the phase transition in mixed organic solvents.The driving force for the transition and concept of polyelectrolyte and ionomer were interpreted with the multiplet formation when decreasing the media polarity.
