Biosensor based on interpenetrated polymer network of alginic acid and poly(1-vinylimidazole )

Kartal, Müjgan
A new proton conductor polymer was prepared using alginic acid (AA) and poly (1-vinylimidazole) (PVI). The polymer network was obtained by mixing AA and PVI at various stoichiometric ratios, x (molar ratio of the monomer repeat units). The AA/PVI network was characterized by elemental analysis (EA) and FT-IR spectroscopy. Potential use of this network in enzyme immobilization was studied. Enzyme entrapped polymer networks (EEPN) were produced by immobilizing invertase and tyrosinase (PPO) in the AA/PVI network. Additionally, the maximum reaction rate (Vmax) and Michaelis-Menten constant (Km) were investigated for the immobilized invertase and enzymes. Also, temperature and pH optimization, operational stability and shelf life of the polymer network were examined.

Çelik, Güler Bayraklı; Kısakürek, Duygu; Department of Chemistry (2007)
Microwave-assisted novel synthesis of poly(dibromophenylene oxide) or poly(diiodophenylene oxide) (P), conducting polymer (CP) and/or crosslinked polymer (CLP) and/or radical ion polymer (RIP) were achieved simultaneously from lithium, sodium or potassium 2,4,6-bromophenolate or sodium 2,4,6-iodophenolate in a very short time interval. Polymerizations were carried out by constant microwave energy with different time intervals varying from 1 to 20 min; or at constant time intervals with variation of microwav...
Synthesis, characterization and electrochromic properties of conducting copolymers of terephthalic acid bis-(thiophen-3-ylmethyl)thioester with thiophene and pyrrole and conducting polymer of 1-(4-fluorophenyl)-2,5-di(thiophen-2-yl)-1h-pyrrole
Türkarslan, Özlem; Toppare, Levent Kamil; Department of Chemistry (2006)
Terephthalic acid bis-(thiophen-3-ylmethyl)thioester (TTMT) was synthesized via the reaction of thiophen-3-ylmethanethiol with terephthaloyl dichloride. Nuclear magnetic resonance (1H-NMR) and Fourier transform infrared (FTIR) spectroscopies were utilized for the characterization of the monomer. This 3-functionalized thiophene monomer was polymerized in the presence of thiophene (Th) and pyrrole (Py) upon constant potential application in acetonitrile/tetrabutylammonium tetrafluoroborate (TBAFB). The result...
Polyaniline: synthesis characterization solution properties and composites
Yılmaz, Faris; Küçükyavuz, Zuhal; Department of Polymer Science and Technology (2007)
Polyaniline was chemically synthesized at three different temperatures of 25, 0, and -25oC, by oxidative polymerization with ammonium peroxidisulfate at equimolar of aniline to oxidant ratio and 1M HCl. The resulted polyaniline was in a powder form which was characterized by several techniques such as: electrical conductivity, elemental analysis, thermal analysis, wide-angle X-Ray diffraction, and scanning electron microscope. The solution properties of the reduced polymer were studied by viscometry, static...

Öztürk, Tuğba; Küçükyavuz, Zuhal; Department of Chemistry (2005)
P-xylene-bis(diethylsulphonium chloride) (PXBDC) monomer was synthesized by the reaction of a,a-dichloro-p-xylene with tetrahydrothiophene or diethyl sulphide. Electrochemical behavior of this monomer (PXBDC) was examined by cyclic voltametry. Polymerization was achieved both by using electrochemical and chemical polymerization techniques. In the electrochemical technique, PPV was synthesized by constant potential electrolysis in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB) solvent-electrolyte ...

Baytekin, Sevil; Küçükyavuz, Zuhal; Department of Polymer Science and Technology (2009)
Conducting polypyrrole (PPy) nanoparticles were synthesized via microemulsion polymerization system. The characterization of PPy nanoparticles was done by Fourier transform infrared spectrometer (FTIR) and scanning electron microscope (SEM). Nanocomposites were prepared by melt-mixing of polypyrrole with polypropylene (PP) and processed with injection molding. The amount of PPy in nanocomposites varied in the range of 1-20% by weight. The effect of PPy nanoparticles on mechanical, electrical properties and ...
