Abstract Details

2013, Master of Science in Polymer Engineering, University of Akron, Polymer Engineering.
The main objective of this thesis is to study neat and nanoparticle functionalized block-copolymer systems that can be ultimately useful in nanoelectronics applications. Block copolymer, polystyrene-block-poly2-vinylpyridine (PS-b-P2VP) was chosen as the main block copolymer to use to model a layered nanocapacitor, with gold as the model nanofiller. Studies were also performed with polystyrene-block-polymethylmethacrylate (PS-b-PMMA), to catalogue the effects of randomly rough surfaces on island and hole formation. Films were prepared on a multitude of conductive, and non-conductive surfaces including rough ITO, smooth ITO, gold-plated silicon, copper-plated silicon, bare silicon, and PEDOT:PSS coated substrates. It was found that a local method of repeated scanning of the block copolymer surface morphology relative to the substrate morphology to measure kinetic of structure evolution by atomic force microscopy (AFM) was reliable only for a few cycles, before it drifted due to AFM accuracy limits. The metallic plated conductive substrates showed faceting with in conjunction with the block copolymer structure. The PS-P2VP films showed very interesting vertical morphology in cast films due to sub-micron domains of copper which were lost upon annealing due to surface wetting by one block. Finally, the model nanoelectric PS-b-P2VP with gold could be annealed into hierarchal 3-tiered structures due to autophobic dewetting of one layer by another.
