| Popis: | The electron-microscopic investigation of various zones of the anisotropic calcium alginate gel obtained by the up-ward diffusion of 10% calcium acetate solution into 2% sodium alginate solution has been carried out. The compounds were prepared by the “freeze-etching” method. The microstructures of two types, reticular and compact ones, are shown to be present in the anisotropic calcium alginate gels. The reticular structure is observed in the dropwise exfoliation zone, in the capillary zone, in the zone of “lenses” and in the “forezone”. The compact one is observed in the membrane and in the zone of “lenses”. |
