Xanthan-curdlan hydrogel complex (XCHC) has been shown capable of retaining moisture up to 5 freeze-thaw cycles (FTCs); however, moisture distribution in the complex in relation to the hydrogel composition and structure remains uncharacterized. In the present study, magnetic resonance imaging (MRI), nuclear magnetic resonance (NMR) relaxometry, rheology, and scanning electron microscopy (SEM) were used to examine the effect of water distribution and interaction with 2.0% aqueous solutions of xanthan, curdla...

Characterization of conducting copolymer of thiophene via pyrolysis mass spectrometry
Levent, Anil; Hacaloğlu, Jale; Toppare, Levent Kamil (2005-12-01)
In this work, structural and thermal characterization of a conducting copolymer of thiophene (PTh) with 2-methylbutyl-2-(3-thienyl)acetate prepared by two different methods has been performed by pyrolysis mass spectrometry techniques. The pyrolysis mass spectrometry data of both components of the copolymer, polythiophene, PTh, poly(2-methylbutyl-2-(3-thienyl)acetate), PMBTA and PTh/PMBTA have been analyzed and compared. It has been determined that when the electrochemical polymerization of thiophene was ach...

© 2022 The AuthorsThe aim of this study was to investigate the pyrolysis products of polyhydroxyalkanoates (PHAs), polyethylene terephthalate (PET), carbon fiber reinforced composite (CFRC), and block co-polymers (PS-b-P2VP and PS-b-P4VP). The studied PHA samples were produced at temperatures of 15 and 50 oC (PHA15 and PHA50), and commercially obtained from GlasPort Bio (PHAc). Initially, PHA samples were analyzed by nuclear magnetic resonance (NMR) spectroscopy and size exclusion chromatography (SEC) to de...
Characterization of conducting copolymer of pyrrole via pyrolysis mass spectrometry
Levent, Anil; Hacaloğlu, Jale; Toppare, Levent Kamil (2008-03-01)
In this work, structural and thermal characterization of BF4- doped copolymer of pyrrole (PPy) with 2-methylbutyl-2-(3-thienyl)acetate prepared by electrochemical polymerization were performed via a pyrolysis mass spectrometry technique. The pyrolysis mass spectrometry data of the copolymer PPy/PMBTA, and the homopolymers; polypyrrole, PPy, and poly(2-methylbutyl-2-(3-thienyl)acetate), PMBTA were analyzed and compared. It has been determined that when the electrochemical polymerization of pyrrole was achiev...
