Abstract

In this study, 5-norbornene-2,3-dicarboxylic acid has been used for the first time as crosslinker to obtain chitosan hydrogels. The formation of ionic crosslinks between chitosan and the diacid has been confirmed by means of IR spectroscopy. The obtained ionic hydrogels have been characterized by means of DSC and rheological tests in the frequency sweep mode. Shear moduli and parameters of the molecular structure of the obtained hydrogel network depending on the diacid concentration have been calculated basing on the rheological data and the generalized viscoelastic Maxwell model.

壳聚糖与 5-降冰片烯-2,3-二羧酸离子水凝胶的合成与流变学研究

本研究首次使用 5-降冰片烯-2,3-二羧酸作为交联剂来获得壳聚糖水凝胶。红外光谱证实了壳聚糖和二元酸之间形成的离子交联。获得的离子水凝胶通过 DSC 和频率扫描模式下的流变测试进行了表征。根据流变学数据和广义粘弹性麦克斯韦模型，计算出了取决于二元酸浓度的水凝胶网络的剪切模量和分子结构参数。

期刊介绍： Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
