Abstract Details

2007, MS, University of Cincinnati, Engineering : Materials Science.
This research focuses on the space-confined P123-silica hybrid self-assembly. Mesoporous silica nanowires with various diameters (10 – 400nm) were synthesized via sol-gel combined vapor-induced self-assembly in both AAO and EPC channels. Scanning transmission electron Microscope (STEM) was used to characterize the samples in terms of nanopore size, ordering, and orientation. The mesoporous structure of silica wires formed in EPC with diameter less than 400 nm are first reported. Substrate effect (EPC vs AAO) and processing condition effect on the morphology of the mesoporous structure of silica wires are present and discussed. The more ordered and uniform mesoporous structure is preferentially formed in narrower substrate channel confinement. A critical diameter (dc) of hard template channels is around 30-50 nm, below which the space confinement effect leads to more uniform nanostructured nanowires; above the dc, mixed mesostrcucture usually exist. The formation of various meso-structures of silica wires is sensitive to process conditions.
