Polymers were prepared from saturated (HMDS) and unsaturated (AN) monomers in a radio frequency discharge (plasma). The effect of selected parameters such as electrode type (such as Cu, Zn, Ni, Al), reactor type, and substrate temperature (other parameters constant) on chemical structure and the rate of polymer deposition was examined by Fourier transform infrared (FTIR) spectroscopy. Differences in the nature of electrodes and reactor types were found to yield similar plasma products with similar rates of deposition for two monomers. In the tubular reactor used, deposition rates were observed to decrease with increasing substrate temperatures showing different dependencies on temperature for the monomers tested.

Studies on the modification of interphase/interfaces by use of plasma in certain polymer composite systems
Akovali, G; Dilsiz, N (Wiley, 1996-04-01)
Calcium carbonate and carbon fiber surfaces were modified by use of a series of plasma polymers at different selected plasma conditions, and the effect of surface modification, mainly on the mechanical properties of composite systems prepared, was investigated. The matrices for the composite systems employed were polypropylene and epoxy, for the chalk and C fiber, respectively. Mechanical and thermal studies and scanning electron microscopy (SEM) pictures revealed that inclusion surfaces, being independent ...
Simultaneous novel synthesis of conducting, nonconducting, and crosslinked polymers by microwave initiation
Çelik, Güler (Wiley, 2006-12-15)
A novel synthesis of poly(dibromophenylene oxide) (P), conducting polymer (CP), and/or crosslinked polymer (CLP), and/or radical ion polymers (RIP) was achieved simultaneously from sodium 2,4,6-tribromophenolate by microwave energy in a very short-time interval. The synthesized polymers were characterized via elemental analysis, FTIR, H-1 NMR and C-13 NMR, X-ray diffraction spectroscopy, SEM, DSC, TGA, ESR, GPC, conductivity measurement, and light scattering. It was found that polymerization proceeds throug...
The Main Electrical and Interfacial Properties of Benzotriazole and Fluorene Based Organic Devices
Yildiz, Dilber E.; APAYDIN, Dogukan H.; KAYA, Emine; Altindal, Semsettin; Çırpan, Ali (Informa UK Limited, 2013-01-01)
Electrical and interfacial properties of ITO/PEDOT:PSS/poly((9,9-dioctylfluorene)-2,7-diyl(2-dodecyl-benzo[1,2,3]triazole)) (PFTBT)/Au devices were investigated using current-voltage (I-V), capacitance-voltage (C-V) and conductance-voltage (G/w-V) measurements at room temperature. The forward and reverse C-V and G/w-V measurements were carried out in the frequency range of 10kHz-1MHz. The electrical parameters, barrier height (phi Bo ) and ideality factor (n) obtained from the forward bias LnI-V plot were f...
Effects of nucleating agent and processing conditions on the mechanical, thermal, and optical properties of biaxially oriented polypropylene films
Yuksekkalayci, C; Yılmazer, Ülkü; Orbey, N (Wiley, 1999-07-01)
The effects of nucleating agent, temperature of crystallization, and degree of machine direction (MD) orientation on the mechanical, optical, and thermal properties of biaxially oriented polypropylene (BOPP) films were investigated. Addition of nucleating agent improved only the initial tear resistance in the MD; however, the other mechanical and optical properties did not change appreciably. Ln the set of experiments in which the crystallization temperature was increased, the degree of crystallinity also i...
STUDIES ON MODIFICATION OF SOME FLAMMABILITY CHARACTERISTICS BY PLASMA .2. POLYESTER FABRIC
AKOVALI, G; TAKROURI, F (Wiley, 1991-05-20)
Cold plasma treatment of polyester fabric in the presence of several volatile monomers containing expected flame retardant elements was made and some of the flammability characteristics of the plasma/monomer-treated fabric were studied. The plasma treatment on the fabric caused a slight decrease in both oxygen index values and burning rates. It is believed that crosslinking outweights the effect of grafted elements. The results of wettability and TGA tests as well as SEM data are included.
