Hydrogen-bonded multilayers of micelles of a dually responsive dicationic block copolymer Erel Göktepe, İrem; Tuncer, Cansel; Butun, Vural; Demirel, A. Levent (2012-01-01) We report the fabrication of hydrogen-bonded multilayers of micelles of a dually responsive, dicationic block copolymer, poly[2-(N-morpholino)ethyl methacrylate-block-2-(diisopropylamino)ethyl methacrylate] (PMEMA-b-PDPA). By taking advantage of the difference in the hydrophilicity of PMEMA and PDPA blocks, micelles with a PMEMA-corona and a PDPA-core were obtained above pH 6.5 and were assembled layer-by-layer at the surface with tannic acid (TA) at pH 7.4 through hydrogen bonding interactions between morp...
Hydrogen-bonded Multilayers of Tannic Acid: Tuning pH Response Erel Göktepe, İrem (null; 2007-02-05)
Hydrogen-bonded multilayers of a neutral polymer and a polyphenol Erel Göktepe, İrem (2008-06-10) We report on association of tannic acid (TA) with neutral or charged polymers in solution and at surfaces and contrast hydrogen-bonded and electrostatically associated polymer/TA complexes and TA/polymer layer-by-layer (LbL) films as per their stability in the pH scale. The neutral polymers used for hydrogen bonding with TA were poly(N-vinylcaprolactam) (PVCL), poly(N-vinylpyrrolidone) (PVPON), poly(ethylene oxide) (PEO), or poly(N-isopropylacrylamide) (PNIPAM), and the polymer used to explore electrostatic...
Hydrogen-Bonded Multilayers With Controllable pH-Induced Disintegration Kinetics for Controlled Release Applications From Surfaces Bağ, Esra; Begik, Oguzhan; Yusan, Pelin; Erel Göktepe, İrem (2015-04-03) We report on incorporation of coordination complexes into hydrogen-bonded multilayers which was found to be an effective method to control pH-induced disintegration kinetics of hydrogen-bonded multilayers. By taking advantage of the strong metal chelating and hydrogen donating properties of Tannic Acid (TA), coordination complexes of Zr4+ and TA (Zr(IV)-TA complexes) were prepared and then self-assembled at the surface using hydrogen accepting polymers such as poly (N-vinyl caprolactam) (PVCL) or poly(N-iso...
Hydrogen-bonded layer-by-layer films of block copolymer micelles with pH-responsive cores Erel Göktepe, İrem; Zhuk, Aliaksandr; Sukhishvili, Svetlana A. (Elsevier BV, 2011-03-01) We report on construction of hydrogen-bonded monolayers and multilayers of micelles of the poly(2-(diethylamino)ethyl methacrylate)-block-poly(N-isopropyl acrylamide) (PDEA-b-PNIPAM) with PNIPAM-corona and polybasic PDEA cores. Films were constructed at pH 7.5 and 25 degrees C to assure the deposition of PDEA-b-PNIPAM in the micellar form. When monolayers of block copolymer micelles (BCMs) were exposed to moderately acidic pH values, micellar cores dissolved, while PDEA-b-PNIPAM remained adsorbed at the sur...
