“…Especially the electrical and optical properties of polymers have been extensively investigated due to their applications in optical devices recently. Polymeric materials have unique properties such as low density, light weight, and high flexibility and are widely used in various industrial sectors [3].…”

In this paper properties of Biaxial-Oriented Polypropylene, Poly Vinyl Chloride and Poly Methyl Methacrylate samples treated by DC glow discharge of N 2 plasma have been investigated by UV-Vis_NIR spectrophotometer. It was found that plasma treatment change chemical structure of polymer surfaces. In addition, absorption coefficient, refractive index and extinction coefficient of all treated samples have been slightly changed.

“…Low density polyethylene (PE) samples with dimensions of 2 Â 2 Â 0.2 cm were inserted into the plasma immersion ion implanter with a copper cathodic arc plasma source [18][19][20][21][22][23][24]. The arc was ignited using a pulse duration of 300 ms, repetition rate of 30 Hz, and arc current of 1 A.…”

“…Moreover, the elements (N, O) have similar in-depth profiles as Cu and their close proximity allows possible physical or chemical interactions with Cu. The peak Cu concentration is about 11% Cu (by comparing the ratio of copper to carbon) and the surface Cu concentration is about 3% which arises from some surface deposition during PIII [18]. The presence of some surface Cu can provide immediate antibacterial effects [8].…”

“…One of the ways to overcome these obstacles is to introduce an inorganic antibacterial reagent like Cu into the subsurface region of the polymer by plasma immersion ion implantation. The embedded Cu layer provides both instantaneous and long term antimicrobial effects [18][19][20][21]. In the work reported here, we investigate the influence of NH 3 , O 2 , or N 2 plasma co-implantation on the Cu release rate from polyethylene and the resulting antibacterial characteristics.…”

“…Plasma Immersion Ion Implantation & Deposition (PIIID) is a highly efficient technique for surface modification and thin film deposition. It can produce or modify metals, semiconductors and polymeric materials [14][15][16][17][18]. In this case, the materials are produced in a gas or vapor discharge and it is polarized simultaneously with high voltage pulses.…”

Abstract. In this work, it was used a plasma system composed of a cylindrical stainless steel reactor, a radio-frequency (13.56MHz) power source fixed at either 25 W or 70 W, a power source with a negative bias of 10kV and a 100Hz pulse. The system worked at an operational pressure of 80mTorr which consisted of varying concentrations of the monomer HMDSN and gaseous nitrogen in ratios: HMDSN (mTorr)/nitrogen (mTorr) from 70/10 to 20/60 in terms of operational pressure. The structural characterization of the films was done by FTIR spectroscopy. Absorptions were observed between 3500 cm -¹ to 3200 cm -¹, 3000 cm -¹ to 2900 cm -¹, 2500 cm -¹ to 2000 cm -¹, 1500 cm -¹ to 700 cm -¹, corresponding, respectively, to OH radicals, C-H stretching bonds in CH2 and CH3 molecules, C-N bonds, and finally, strain C-H bonds , Si-CH3 and Si-N groups, for both the 70 W and the 25 W.The contact angle for water was approximately 100° and the surface energy is near 25mJ/m² which represents a hydrophobic surface, measured by goniometric method. The aging of the film was also analyzed by measuring the contact angle over a period of time. The stabilization was observed after 4 weeks. The refractive index of these materials presents values from 1.73 to 1.65 measured by ultraviolet-visible technique.
