Gaseous plasmas are suitable for various applications in material science, including but not limited to thin film productions and coatings, tailoring the surface properties of polymers. This study aims to characterize a capacitively coupled plasma system utilized in material processing applications. The system utilizes a 13.56 MHz radio frequency source to produce gaseous plasmas. The correlation between the produced plasmas and the surface physical and surface chemical properties of polypropylene treated by such plasmas are in the interest of many novel research applications. The treatments are done using Argon and Nitrogen plasmas separately, while the flow rates of all gasses are controlled using a multi-gas controller. Investigations of changes on PP surface are done employing FTIR-ATR, XRD, SEM analyses. Results of this study, the crystallinity of PP surface is improved, and newly formed chemical and physical structures are observed.

Surface characterization and radical decay studies of oxygen plasma-treated PMMA films Ozgen, Ozge; Aksoy, Eda Ayse; Hasırcı, Vasıf Nejat; Hasırcı, Nesrin (2013-04-01) Polymethylmethacrylate (PMMA) films were modified by RF oxygen plasma with various powers applied for different periods, and the effects of these parameters on the surface properties such as hydrophilicity, surface free energy (SFE), chemistry, and topography were investigated by water contact angle, goniometer, X-ray photoelectron spectroscopy (XPS), and atomic force microscopy, and the types of the created free radicals and their decay were detected by electron spin resonance spectroscopy (ESR). SFE and c...
Oxygen plasma modification of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) film surfaces for tissue engineering purposes Hasırcı, Vasıf Nejat; Tezcaner, Ayşen; Hasırcı, Nesrin (2003-02-22) Plasma glow-discharge application is known as a technique to coat or modify the surfaces of various materials. In this study, the influence of oxygen rf-plasma treatment on surface and bulk properties of a biological polyester, poly(3-hydroxybutyrate-co-3-hydroxyvalerate), were studied by determining water content and water contact angle, and by using X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The plasma-treated films absorbed more water than the untreated film, and the a...
Thermally Induced Phase Transition and Defect-Assisted Nonlinear Absorption and Optical Limiting in Nanorod Morphology V2O5 Thin Films Pepe, Yasemin; Tutel, Yusuf; Yildiz, Elif Akhuseyin; Karatay, Ahmet; Ünalan, Hüsnü Emrah; Elmalı, Ayhan (2021-01-01) © 2021 Wiley-VCH GmbHVanadium pentoxide (V2O5) thin films are greatly favorable materials for optoelectronic applications due to their broad optical bandgap and considerable thermal and chemical stability. Herein, the influence of thermal treatment on the microstructure related to the nonlinear optical, optical limiting, and phase transition behaviors of V2O5 thin films produced via ultrasonic spray deposition method onto FTO/glass substrates is systematically examined by Z-scan experiments. Homogenous and ...
Mechanical properties and surface energies of low density polyethylene poly(vinyl chloride) blends Akovali, G; Torun, TT; Bayramlı, Erdal; Erinc, HK (1998-03-01) A series of blends of poly(vinyl chloride) (PVC) and low density polyethylene (LDPE) are prepared and examined. Plasma treatment is applied to one of the components (LDPE) in order to affect the degree of compatibility. For this purpose, different monomers, such as carbon tetrachloride and vinyl chloride, are used. Tensile test results for all the blend samples, with and without plasma-treated LDPE, are compared. The surface energy results of blends prepared from untreated and treated LDPE-PVC showed consid...
A Study of Crystallization in Plasma Modified Polypropylene Mansuroglu, Dogan; Mecit, Giray; Uzun Kaymak, İlker Ümit (2019-01-01) A capacitively coupled radio-frequency plasma discharge is used to improve the surface properties of Polypropylene. The changes in the surfaces are investigated for various plasma discharge parameters. After the plasma modification, the polypropylene material transforms into a para-crystalline form and shows the properties of the monoclinic crystals dominantly, observed using the X-ray diffraction measurements. The results indicate significant improvements in the crystallinity after the plasma exposure. The...
