Abstract Details

2015, Doctor of Philosophy, University of Akron, Polymer Engineering.
The most widely used n-type material for organic electronics is 1-(3-methoxycarbonyl)propyl-1-phenyl[6,6]C61, (PCBM). In this dissertation we present the role of solvents and interfaces on the dispersion of PCBM in as cast and post processed thin polymer films. First we investigated the selective dispersion of PCBM in one phase of a self-assembled diblock copolymer thin film by controlling the polymer-PCBM interaction in a mixed solvent during the spin casting process. Subsequently, we studied the effect of casting solvents on the morphological evolution of drop cast model P3HT:PCBM films. It is observed that casting solvents affect the crystallization of P3HT and PCBM as well as crystal orientations of P3HT. We also studied the in-situ solvent annealing process of P3HT:PCBM thin films by grazing incidence wide angle X-ray scattering (GIWAXS). In a separate study we investigated the morphological evolution of o-dichlorobenzene cast P3HT:PCBM thin films due to thermal annealing under dual confinement. PCBM microcrystal formation was suppressed due to such confinements. However, different characterization techniques show that nano-scale morphological evolution takes place even under such confinements. It was found that casting solvent plays a critical role in the final morphology of such thermally annealed thin films. Therefore, in this dissertation we have demonstrated the effect of solvent processing and interfacial properties in annealed PCBM:polymer thin films.
