dc.description.abstractIn this work, a few techniques were developed. Among these techniques, a simple method to transfer aligned multi-walled carbon nanotubes (MWNTs) is demonstrated. With polydimethylsiloxane (PDMS) as the transfer medium, as-grown/patterned MWNT arrays are directly transferred onto a wide variety of platinum (Pt)-coated substrates at low temperatures. Using the transfer technique, studies on the effect of hydrostatic dilation stress to the formation of MWNT microstructures were investigated. By preventing interactions between the assembly solvent and the substrate; and embedding the MWNTs in the PDMS, no formations of MWNT polygons were observed on the pre-pattened MWNTs array. Using three different capillarity assisted techniques, large scale formations of non-transferred MWNT based micro-structures are created. In addition to capillarity induced formations of large scale MWNT micro-structures, microstructures, specifically micro-walls, were also found to bring about improvements in the hydrophobic nature of the MWNT surfaces.
