PERMEABILITY OF NANOPOROUS GLASSES
Annotation
The permeability of nanoporous glasses with the pore radius of 5–200 nm is studied. Such porous glasses are used as thin filters, optical materials with adjustable refractive index, solid adsorbents, selective membranes, and as the basis for composite materials in laser technology and optical instrument making. Models of the structure and methods for calculating the molecular permeability of such materials are proposed. Results of calculation using the proposed models are compared with experimental data.
