The objective of this study was to fabricate and characterize Hydroxypropyl methylcellulose (HPMC) - based homogenous nanofibers by using electrospinning method. As the concentrations of the solutions increased, viscosity and electrical conductivity of the solutions increased. The morphology of the fibers changed from the beaded structure to the uniform fiber structure by increasing the concentrations of the solutions. Water vapor permeability (WVP) of electrospun HPMC nanofibers decreased with increasing polymer concentration. The shift in wavelengths, the change in intensity of FTIR peaks and melting point depression were the evidence of miscibility of HPMC/PEO blends. Nanofibers showing both melting temperature (T-m) and glass transition temperature (T-g) had semicrystalline structure. By combining PEO with HPMC, the thermal stability of nanofibers was increased. Hence, this study suggests homogenous biopolymer-based nanofibers with low WVP and high thermal stability which can have potential applications in food packaging field.

A MECHANISTIC STUDY ON THE STEREOREGULAR POLYMERIZATION OF PROPYLENE-OXIDE BY THE PRUITT-BAGGETT CATALYST TAKROURI, F; ALYURUK, K (Elsevier BV, 1994-01-01) The structures of the Pruitt-Baggett adduct (PBA) and the Pruitt-Baggett catalyst (PBC) were studied in some detail. PBC extensively ionizes in acetonitrile (K(d)=3.48 x 10(-3) mol l-1 at 25-degrees-C) producing an anionic fragment composed of seven Fe atoms and a cationic fragment with two Fe atoms. Hittorf electrolysis showed that the anionic fragments exclusively bore the high molecular weight stereoregular poly(propylene oxide)s (K-polymers). However, study of the polymerization in the presence of anion...
A new approach for the synthesis of spiro and gem-dimethyl-substituted 1,4-oxazepines from N-propargylic beta-enaminones Karadeniz, Eda; Kelgökmen, Yılmaz; Zora, Metin (Wiley, 2020-11-01) An efficient and general method for the synthesis of spiro-1,4-oxazepines and 3,3-dimethyl-1,4-oxazepines is reported. When treated with ZnI2 and AgSbF6 in refluxing DCE, cyclohexane-embedded N-propargylic beta-enaminones underwent 7-exo-dig cyclization to afford spiro-1,4-oxazepines, specifically 12-methylene-11-oxa-7-azaspiro[5.6]dodeca-7,9-dienes, in good to high yields. Accordingly, N-(1,1-dimethyl)propargylic beta-enaminones produced 3,3-dimethyl-1,4-oxazepines. Cyclization was found to be general for ...
Effects of Halloysite Nanotubes on the Performance of Plasticized Poly(lactic acid)-Based Composites Erpek, Canan Esma Yeniova; ÖZKOÇ, GÜRALP; Yılmazer, Ülkü (Wiley, 2016-11-01) The objective of this study is processing and characterization of Halloysite nanotube (HNT)/poly(lactic acid) (PLA) nanocomposites. As HNT filler, a domestic source was used (ESAN HNT). The results obtained from this HNT were compared with a well-known reference HNT (Nanoclay HNT). To achieve the desired physical properties and clay dispersion, composites were compounded via direct melt mixing in a laboratory twin-screw compounder. However, the constituents were observed to be incompatible without a compati...
Preparation of Gadolina Stabilized Bismuth Oxide Doped with Boron via Electrospinning Technique TUNÇ, TUNCAY; Uslu, Ibrahim; Durmusoglu, Senol; Keskin, Selda; Aytimur, Arda; Akdemir, Ahmet (Springer Science and Business Media LLC, 2012-01-01) In this study, boron doped and undoped poly (vinyl) alcohol/bismuth-gadolina acetate (PVA/Bi-Gd) nanofibers were prepared using electrospinning technique then calcinated at 800 degrees C for 2 h. The originality of this study is the addition of boron to metal acetates. The effects of boron doping were investigated in terms of solution properties, morphological changes and thermal characteristics. The characteristics of the fibers were investigated with FT-IR, XRD, SEM and BET. The addition of boron did not ...
Study on mechanical properties of perlite-filled gamma-irradiated polypropylene Akin-Oktem, G; Tanrisinibilir, S; Tincer, T (Wiley, 2001-09-12) This study covers the preparation and characterization of perlite-filled polypropylene (PP). The compositions of 15, 30, and 50 % by weight perlite-PP composites were prepared by melt-mixing. The PP used in this study was either applied in the virgin form or gamma -irradiated in air at the doses of 10, 25, 50, and 100 kGy to determine the effect of oxidative degradation in composite properties. Furthermore, the active sites containing oxygen produced by gamma -irradiation in PP may provide a possible enhanc...
