Spray processable ambipolar benzotriazole bearing electrochromic polymers with multi-colored and transmissive states

Hızalan, Gönül
The interest towards organic semi-conductors increased due to their tunable band gaps, redox properties, processability and low cost in the field of conducting polymers. Electrochromic materials have the ability to change color by altering their redox state. In the context of low cost flexible display device technology, requirements can be fulfilled with accessible multi-colored electrochromic polymers. In this study, we report the chemical synthesis and electrochromic properties of two spray processable, ambipolar, fluorescent and multi-color to transmissive electrochromic polymers. The electrochromic properties of these polymers were examined by cyclic voltammetry, spectroelectrochemistry, kinetic studies. Polymers, PTBTPh and PTBTTh, have multi-colored oxidation states and easily accessible ndoped states, which allowed us to achieve transmissive films in a low working potential. Electrochemical and spectral results showed that both polymers are potential materials for electrochromic display devices.


Syntheses of benzotriazole bearing donor acceptor type random copolymers for full visible light absorption
Öktem, Gözde; Toppare, Levent Kamil; Department of Chemistry (2011)
The synthesis and preliminary optoelectronic properties of a series of donor-acceptor (DA) type polymers differing by the acceptor units in the polymer backbone were investigated. Polymers CoP1, CoP2 and CoP3 were designed to yield alternating DA segments with randomly distributed different acceptor units along polymer backbone. The combination of neutral state red colored and neutral state green colored materials resulted in different neutral state colors with respect to their additional acceptor unit. 5,8...
Synthesis and characterization of copolymers of diisocyanates and dialcohol
Keskin, Selda; Usanmaz, Ali; Department of Polymer Science and Technology (2008)
This study was aimed to synthesize low molecular weight hydroxyl terminated polyurethane acrylate polymers that can be used in biomedical applications. Acrylate end capping via inter-esterification reaction was successfully achieved with the methacryloyl chloride addition to the hydroxyl ends of the polyurethane at low temperatures. Isocyanate terminated polyurethane acrylates were also synthesized for the sake of comparison. TDI, HDI and MDI were used as diisocyanates for urethane synthesis and they were e...

Ecevit, Safiye Tuba; Aras, Leyla; Tinçer, Teoman; Department of Polymer Science and Technology (2012)
The synthesis of ion-exchange resin which can be used in various separation and chemical purposes, such as diffusion dialysis, electro dialysis, electrolysis and fuel cells has of considerable interest. For all these applications, the interactions of the ionic groups and the resulted morphologies are critical for establishing the unique properties. Considerable researches have been continued to understand the microstructure of these materials. The aim of this study is to synthesize polypropylene (PP) based ...
Synthesis and characterization of polythiophene/montmorillonite and polythiophene/polypropylene composites
Dülgerbaki, Çiğdem; Küçükyavuz, Zuhal; Department of Chemistry (2006)
In this study, polythiophene(PTP)/montmorillonite(MMT) nanocomposites were synthesized by in situ intercalative polymerization and chemical oxidative polymerization. In in situ intercalative polymerization method, composites containing 90 and 95% MMT were prepared. In chemical oxidative polymerization method, a series of composites ranging from 1 to 15% by weight MMT were synthesized. Thermal and morphological properties of samples were investigated by Differential Scanning Calorimeter (DSC), Thermal Gravim...
Abs/polyamide-6 blends, their short glass fiber composites and organoclay based nanocomposites: processing and characterization
Özkoç, Güralp; Bayram, Göknur; Department of Polymer Science and Technology (2007)
The objective of this study is to process and characterize the compatibilized blends of acrylonitrile-butadiene-styrene (ABS) and polyamide-6 (PA6) using olefin based reactive copolymers and subsequently to utilize this blend as a matrix material in short glass fiber (SGF) reinforced composites and organoclay based nanocomposites by applying melt processing technique. In this context, commercially available epoxydized and maleated olefinic copolymers, ethylene-methyl acrylate-glycidyl methacrylate (EMA-GMA)...
