  1. Chemical seeding via propanol plasma pretreatment for improving adhesion and properties of PECVD siloxane coatings on polymers

    Jonathon F. S. Markanday, Eric Charrault, Drew Evans, Kamil Zuber and Colin Hall

    Incorporation of hydroxyl groups at the start of the deposition via a propanol plasma pretreatment alter the seeding and growth of a thin film and give rise to mechanical and optical property changes. The plasma pretreated samples exhibited increased hardness and modulus and serve to illustrate how pretreatments may be used for alteration of thin film properties other than adhesion.

  2. Deterministic and Monte Carlo methods for simulation of plasma-surface interactions

    A review of methods to model surface chemical kinetics in reactive plasmas is presented. Deterministic models are formulated in terms of coverages of surface active sites while in Monte-Carlo simulations individual surface species are followed independently. We show that both approaches give identical results when applied to a simple model systems. However, the advantage of Monte-Carlo methods is that they can be used to simulate kinetics on realistic disordered surfaces.

  3. Modeling of Thermal Plasma Processes: The Importance of Two-Way Plasma-Surface Interactions

    The effect of materials on the plasma is often neglected in computational models of thermal plasma applications, even though most models consider the influence of the plasma on the surface. However, in many applications (including plasma cutting, spheroidization, nanoparticle production and spraying, arc welding and circuit interruption), effects such as vaporization of the surface material and heat transfer to particles mean that two-way interactions are critical.

  4. Critical remarks on chemical derivatization analysis of plasma-treated polymer surfaces and plasma polymers

    Claus-Peter Klages and Stefan Kotula

    The traditional belief that amino groups of plasma-treated polymer surfaces or plasma polymers can be quantified using derivatization with “amino-selective” reagents is a myth. Amino group concentrations in the literature must generally be considered to include substantial contributions from other nitrogen-containing groups, e.g., imines. It is questionable if amino groups are stable against plasma or VUV exposure at all. Advancing the understanding of plasma-generated films and surfaces requires new approaches such as FT-IR spectroscopy combined with H/D isotope exchange.

  5. An atmospheric-pressure microplasma array produced by using graphite coating electrodes

    An array of atmospheric pressure plasma jets can be used for large-surface plasma treatment at atmospheric pressure. An easy assembled atmospheric-pressure microplasma array (APMPA) with graphite coating electrodes was presented in this study. The measurements show that the APMPA could achieve excellent jet-to-jet uniformity both in time and in space. This design may remove the structure limitation of the microplasma array and have a beneficial effect on various applications.
