Intrinsic properties of organic semiconductors are investigated by Time-Resolved Terahertz Spectroscopy (TRTS) to assess their relative mobilities and efficiencies. Our results are well correlated with device measurements and show the effectiveness and advantages of using this non-contact optical technique to rapidly identify prospective materials. After a brief introduction of the TRTS technique, we summarize our results from relative mobility measurements of the organic semiconductor polymers poly(3-hexylthiophene) (P3HT) and poly(2,5-bis(3-tetradecylthiophen-2yl)thieno[3,2-b]thiophene (PBTTT) as model active layers in transistor devices. We also synopsize our recent results from relative efficiency studies of blend and alternating multilayer films of zinc phthalocyanine (ZnPc) and buckminsterfullerene (C60) as model active nanolayers for efficient solar cells.

Nanocomposites based on blends of polyethylene
Işık, Fatma; Yılmazer, Ülkü; Department of Chemical Engineering (2005)
In this study the effects of compatibilizer type, organoclay type, and the addition order of components on the morphological, thermal, mechanical and flow properties of ternary nanocomposites based on low density polyethylene, LDPE were investigated. As compatibilizer, ethylene/methyl acrylate/glycidyl methacrylate, ethylene/glycidyl methacrylate, and ethylene/butyl acrylate/maleic anhydride; as organoclay Cloisite? 15A, Cloisite? 25A and Cloisite? 30B were used. All samples were prepared by a co-rotating t...
Pyrolysis mass spectrometric analysis of copolymer of polyacrylonitrile and polythiophene
Oğuz, Gülcan; Hacaloğlu, Jale; Department of Polymer Science and Technology (2004)
In the first part of this work, the structural and thermal characteristics of polyacrylonitrile, polyacrylonitrile films treated under the electrolysis conditions in the absence of thiophene, polythiophene and the mechanical mixture and a conducting copolymer of polyacrylonitrile/polythiophene have been studied by pyrolysis mass spectrometry technique. The thermal degradation of polyacrylonitrile occurs in three steps; evolution of HCN, monomer, low molecular weight oligomers due to random chain cleavages a...
Nanocomposites based on recycled poly(ethylene terepthalate)
Tolga, Aslı; Yılmazer, Ülkü; Department of Chemical Engineering (2005)
In this study, the effects of glycol type, organoclay type and concentration on the final properties of nanocomposites based on recycled poly(ethylene terephthalate) was investigated. For this purpose, first recycled PET was glycolysed and after that unsaturated polyester-montmorillonite nanocomposites were synthesized by using three different types of glycols (i.e. ethylene glycol (EG), propylene glycol (PG) and diethylene glycol (DEG)). As the first step, all the compositions were prepared by Cloisite 30B...
