It is found that adding boehmite nanoparticles to a sodium–carboxymethyl cellulose suspension with glycerin and aluminum powder allows the formation of films with ordered pores (cells of 1200–600 μm in size). X-ray diffraction and infra-red spectroscopy reveal no changes in the chemical composition of films upon their solidification. The surface porosity of the films is established to be 65%. The developed porous composites are shown to be promising in the fabrication of antifriction coatings.
