  1. Understanding the Morphogenesis of Nanostructures in Maleic Anhydride Plasma Polymer Films via Growth Kinetics and Chemical Force Titration

    Michel M. Brioude, Marie-Pierre Laborie, Hamidou Haidara and Vincent Roucoules

    An original approach was used to understand the structures formation and chemistry in maleic anhydride plasma polymer films based on growth kinetics and chemical force titration. Growth kinetics showed initial formation of beads followed by random formation of complex structures. Chemical force titration revealed differences in the global chemistry, associated to the presence of the structures.

  2. Epi-fluorescence Microscopy as a Tool for Relative Quantification of the Anti-Biofouling Character of Atmospheric Pressure Plasma-Polymerized Biomaterials

    Bernard Nisol, Anne Meunier, Claudine Buess-Herman and François Reniers

    The present study describes a user-friendly and efficient epi-fluorescence protocol for the evaluation of the anti-biofouling potential of a set of atmospheric pressure plasma-polymerized polyethylene glycol coatings. By means of a systematic study, we can underline that fluorescence microscopy allows the direct observation of the anti-biofouling character of new materials.

  3. Influence of Plasma Chamber Set-Up on the Surface Modification of Non-Vulcanized and Pure SBR Rubber Treated at Radio-Frequencies Air Plasma

    Non-vulcanized styrene-butadiene rubber (SBR) thin films were exposed to radio-frequency (RF) low-pressure air plasma. Two different phenomenological mechanisms are proposed to describe the observed differences and account for the impact of the activated gas phase on the structure of plasma-treated non-vulcanized SBR surface.

  4. Preparation of Hydrophobic Viscose Fabric Using Nitrogen DBD and Copper Ions Sorption

    Ana D. Kramar, Bratislav M. Obradović, Alenka Vesel, Milorad M. Kuraica and Mirjana M. Kostić

    Article first published online: 31 MAR 2015 | DOI: 10.1002/ppap.201400228

    Wettability of viscose is evaluated after DBD treatment in nitrogen and it is found that treatment reduced hydrophilicity of viscose. During DBD treatment, removal of polar hydroxyl groups and increase of roughness occurr on the fabric surface which impair interaction with water. Sorption of copper ions onto DBD treated viscose occupy remaining polar groups and cause the petal effect on viscose fabric.

  5. A Simple Technique to Improve Contractile Effect of Cold Plasma Jet on Acute Mouse Wound by Dropping Water

    Nasruddin, Yukari Nakajima, Kanae Mukai, Emi Komatsu, Heni Setyowati Esti Rahayu, Muhammad Nur, Tatsuo Ishijima, Hiroshi Enomoto, Yoshihiko Uesugi, Junko Sugama and Toshio Nakatani

    Article first published online: 30 MAR 2015 | DOI: 10.1002/ppap.201400236

    A simple technique is tested to improve the contractile effect of plasma on wounds. Water is dropped on wounds before treatment.To evaluate its effect, macroscopic and microscopic studies are performed. We show that combination treatment of plasma with water appeared to promote the wound contractile effect compared with plasma alone. Plasma may modify wounds via water, chemically and physically.
