Studying the parameters effect of the sputtering yield for polypropylene bombarding by ions of atmospheric background gases

Using the transport of ions in matter program which is TRIM that based on a Monte Carlo simulation method to calculate sputtering yield for polypropylene, was bombed with (N2, O2, and Ar) gas energy range (0.1-300) Kev different angles. It can be seen from results this study depends incident angle, energy, atomic number ions, surface binding elements make up polypropylene (pp) polypropylene. noted increases increasing Incident angle (θ), increase slight when less than 600, clearly quickly 600 800, then decreases significantly greater 800. In addition, detonation ion until it reaches highest value due amount transferred detonating polymer atoms. We note bombardment
