Nanocompression of secondary particles of silica aerogel

摘要: Abstract The compression of highly porous silica nanospheres is investigated using molecular dynamics simulations and modeling. ligaments network (3–6 nm) nano-sized sustains the load nanoparticles deform plastically due to localized shear events, at junctions between ligaments. Dangling are more numerous as size nanosphere decreases, thus impacting mechanical response. Based on simulation results, we propose a scaling law that describes particle effect indentation force when applied aerogel secondary under compression.
