Obtaining and studying the properties of a polyvinyl alcohol/sodium alginate hydrogels

Obtaining of nano-oxide coatings by anodizing metals is a modern and inexpensive method for producing nanostructures with unique properties. Nanomaterials have attracted the attention of many researchers due to their unique properties in the fields of electricity, optics and magnetism. Anodized porous aluminum oxide is easy to prepare, and the choice of different electrolysis conditions makes it easy to control the nanopore size. Nanopores can be 15 to 200 nm in diameter and up to 100 ym deep. Porous alumina has a wide range of applications: membrane technologies, a matrix for template synthesis of nanowires or nanotubes, and as biosensors or reactors. In this work, porous membranes of aluminum oxide were obtained by the method of two-stage anodic oxidation of aluminum A97. The structure of porous membranes has been studied by atomic force microscopy and transmission electron microscopy.
