Research Abstract

This study proposed a multiscale self-assembly that combines the growth of ordered nanocolumns by glancing angle deposition and the assembly of colloidal nanoparticles by utilizing capillary force. SiO2 column-particle nanocomposites were fabricated by the multiscale self-assembly. Loading experiments with a flat punch indenter revealed that the nanocomposites have excellent mechanical properties as well as large surface areas.
