Scanning electron microscopy (SEM). Hydrogel samples were placed in 2 ml Eppendorf microtubes, frozen in liquid nitrogen (T = -195.75 °С)for 15 min, then transferred to a pear-shaped flask, which was connected to freeze dryer Liofilizator Alpha 1-2 LD plus (CHRICT, Munich, Germany) equipped with a two-stage oil pump RZ 2.5 (VACUUMBRAND), pressure 0.1 mbar (10 Pa), temperature -55 °С. The dried samples were gold-covered in a nitrogen atmosphere (Pump/Gold JEOL JFC-1300), photographs of the morphology were taken on a scanning microscope (JEOL, JSM 6510 LV).
