“…In this work, we study the possibility of forming porous matrices from aqueous solutions of PAC to create functional coatings on their basis by filling pores with dispersed materials with different properties. Ordered pores in films are generated in the presence of water-soluble polymers of aluminum oxyhydroxide (AlOOH) in suspensions [20]. Improvement of mechanical and anticorrosive properties of coatings with the introduction of aluminum into them is confirmed by the studies described in the works [22,23].…”

“…The main obstacle in the operation of such coatings is the ability of these materials to dissolve in water. We have previously shown the possibility of using functional composite coatings and porous films based on carboxymethyl cellulose polymer in aggressive media with a low water content [19,20]. Currently, polyanionic cellulose (PAC) is of great scientific and practical interest of researchers.…”

New porous films based on polyanionic cellulose with AlOOH nanoparticles have been developed. The morphology of the films has been studied by electron microscopy: the size of the formed pores is 1000-500 microns; the total surface porosity of the films is 30%. Using infrared microscopy, it was shown that during the formation of porous films, their chemical composition remains unchanged. Differential scanning calorimetry was used to determine the threshold for thermal destruction of porous films: 306 С. The possibility of using the obtained materials as antifriction coatings when filling the pores with solid lubricant MoS2 is considered. It is shown that for a steel sample protected by a porous coating with MoS2, the friction coefficient decreases by 50% compared to the friction coefficient for a steel surface under a load of up to 450 MPa.
