Electrochemically produced graft copolymers of thiophene capped polytetrahydofuran (TPTHF1 and TPTHF2) and pyrrole were achieved by constant potential electrolysis using sodium dodecylsulfate (SDS) as the supporting electrolyte. Characterizations were based on Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Electrical conductivities were measured by the four-probe technique.
Preparation and characterization of acrylonitrile-ethyl methacrylate copolymers and the effect of LiClO4 salt on electrical properties of copolymer films
VARGÜN, ELİF; SANKIR, MEHMET; Usanmaz, Ali; Kanbur, Yasin; ABACI, UFUK; GÜNEY, HASAN YÜKSEL (2012-04-05)
Copolymers of poly(acrylonitrile-co-ethyl methacrylate), P(AN-EMA), with three different EMA content and parent homopolymers were synthesized by emulsion polymerization. The chemical composition of copolymers were identified by FTIR, H-1-NMR and C-13-NMR spectroscopy. The thermal properties of copolymers were modified by changing the EMA content in copolymer compositions. Various amounts of LiClO4 salt loaded (PAN-co-PEMA) copolymer films were prepared by solution casting. The dielectric properties of these...
Preparation of porous Ca-10(PO4)(6)(OH)(2) and beta-Ca-3(PO4)(2) bioceramics
Engin, NO; Tas, AC (2000-07-01)
Submicrometer-sized, pure calcium hydroxyapatite (HA, (Ca-10(PO4)(6)(OH)(2))) and eta-tricalcium phosphate (beta-TCP, Ca-3(PO4)(2)) bioceramic powders, that have been synthesized via chemical precipitation techniques, were used in the preparation of aqueous slurries that contained methyl cellulose to manufacture porous (70%-95% porosity) HA or beta-TCP ceramics. The pore sizes in HA bioceramics of this study were 200-400 mu m, whereas those of beta-TCP bioceramics were 100-300 mu m. The pore morphology and ...
Preparation of high performance acrylonitrile copolymers
Aran, Bengi; Bengi, Aran; Department of Polymer Science and Technology (2009)
Acrylonitrile based engineering random copolymers were prepared via one step emulsion polymerization using ammonium persulfate (initiator), 1-dodecanthiol (chain transfer agent) and DOWFAX 8390 (surfactant) in the presence of water at approximately 65 0C. Three copolymer compositions were studied for novel polyacrylonitrile, (PAN)-polyhydroxyethyl acrylate (PHEA), PAN-polybutyl acrylate (PBA), novel PAN-polyt-butyl acrylate (PtBA), PAN-polyethyl acrylate (PEA) and PAN-polymethyl acrylate (PMA) with acrylate...
