Abstract
In the work, an experiment was performed to simulate the process of chitosan microtube formation through the interphase polysalt → polybase chemical reaction, on the one hand, and the formation of spatially separated structures under the conditions of reactive diffusion of one of the components, on the other hand. The formation of alternating dark and light bands or concentric rings of the chitosan polybase as a result of the polymer-analogous transformation is visualized by optical microscopy. The results obtained confirm our assumption that the layered structure of our chitosan microtubes is formed according to the Liesegang reaction mechanism.
