Material and new polymers have become ubiquitous material in modern manufacturing processes and offer a wide variety of chemical and mechanical properties applicable to numerous problems. Often, the surface properties of a polymer will preclude its use in an application to which its mechanical properties may be very well suited .For changing this properties we can use of low temperature plasma . In the last paper we investigated the effect of oxygen plasma on the BOPP[1]. In this work we use of, BOPP (22.75 g/m2, thickness of 25 mm, density of 0.91 g/cm3) from Poushineh plastic Co. (Tehran-Iran) treated in plasma chamber. Two plane parallel metal electrodes are connected to an D.C. power supply with an output voltage up to 10kV. The vacuum of the 10-1Pa was achieved by a rotary pump followed by a diffusion pump, which then was increased to 10-3Pa. By introduction of gases, the pressure was adjusted to 10Pa.
We have investigated the effects of differents gases (Argon, Nitrogen, Helium, Hydrogen, Oxygen) on polymers surface modification and compare them together by using of Scanning Electron Microscope (SEM). The details will be discussed in full paper.
