Resumo
The morphology of monodisperse spherical mesoporous silica particles with a regular pore structure is studied with atomic force microscopy. The size of nanotubes is found: the internal diameter is 2.6 nm, the external diameter is 4.8 nm, and the wall thickness is 1.1 nm. A method for assessing the strength parameters of highly porous materials is proposed. The calculated Young’s modulus of a nanotube along its axis is 91.7 GPa.
