STEM characterization on silicananowires with new mesopore structures by space-confined self-assembly within nano-scale channels
文献信息
Michael Z. Hu, Donglu Shi, Douglas Blom
“Critical” channel diameters were found (below which space confinement takes effect, leading to more uniform and ordered mesopore structures) in the study of evaporation-induced co-assembly of triblock-copolymer (P123) and silica molecular precursors (TEOS, tetraethyl orthosilicate) by employing channels in anodized aluminum oxide (AAO, 13–200 nm channel diameter) and in track-etched polycarbonate (EPC, 10–80 nm channel diameter) and for the first time we have observed a new mesopore structure (i.e., packed hollow spheres) in silica nanowires formed in AAO channels with diameters from 30 to 80 nm.
