In this study, functional-group-retaining polymerization of hydroxyethyl methacrylate (HEMA) was carried out by using an atmospheric pressure non-equilibrium Ar plasma jet. The polymeric films deposited under different conditions were characterized by Fourier transform infrared spectroscopy (FT-IR). The FT-IR spectra show that HEMA was polymerized (carbon-carbon double bond disappeared) and the main functional groups were successfully retained in the plasma-polymerization films. The plasma-polymerization mechanism and the polymerization reaction kinetics will be discussed.

Thermal equilibrium hydrogen plasma at atmospheric pressure were simulated using the software matrix laboratory (MATLAB). Runge Kutta method numerical method as a settlement of differensial model equations of chemical kibetik with the arrhenius equation approach and continuity equations so that the equilibrium density values for each species were obtained.  Equilibrium hydrogen plasma at atmospheric pressure and density rate review every reaction involved.  Parameter of ionizing   and disasosiasi  as a reference equilibrium plasma.  Equilibrium plasma is found in time interval 10-6 – 10-3 s thermal hydrogen plasmas with temperatures of 1 eV.  The density  of hydrogen plasma thermal equilibrium overall are in the interval of 1014 m-3 - 1020 m-3 . The reaction rate of each species varies based on the type of collision and rate of change of species.
