NANOSTRUCTURAL OXIDE FIBERS FOR COMPOSITES

摘要

The developed technology makes it possible to synthesize long and short nanostructured polycrystal oxide fibers with high porosity that are characterized by mesoporosity and a large specific surface. The study performed permitted us to establish the mechanism for formation of fibrous oxide with a complex architecture, including metal oxide nanoparticles, nanopores and microcapillaries. Based on the calculations of crystallite sizes, it is found that crystallographic transformations of fiber oxides cause substance to disperse. Structural changes in fibrous oxides are followed by varying the porosity nature, pore size and a value of specific surface. The obtained regularities permit us to predict the properties and to control the technology of producing nanostructural fibrous oxide materials.
