- Plasma Deposition of Thermo-Responsive Thin Films from N-Vinylcaprolactam
Maryline Moreno-Couranjou, Fabio Palumbo, Eloisa Sardella, Gilles Frache, Pietro Favia and Patrick Choquet

Plasma polymerization of N-vinylcaprolactam is reported as an interesting alternative to the toxic N-isopropylacrylamide use for the production of thermo-responsive coatings for potential applications in tissue culture or microfluidics. By combining ToF-SIMS and MALDI-MS analyses, different oligomer distributions in the deposited films are detected and accurately identified.
- In Situ Generation of Plasma-Polymer Standards by Plasma Assisted Free Radical Polymerization
Thierry Fouquet, Grégory Mertz, Claude Becker, Ludivine Fetzer, Fabio Ziarelli and David Ruch

Intermediate polymeric materials between conventional polymers and plasma-polymers – produced via a plasma assisted free radical polymerization – were thoroughly analyzed by MS, NMR and SEC and proposed as new analytical standards.
- Approaches to Quantify Amine Groups in the Presence of Hydroxyl Functional Groups in Plasma Polymerized Thin Films
Juan-Carlos Ruiz, Shima Taheri, Andrew Michelmore, David E. Robinson, Robert D. Short, Krasimir Vasilev and Renate Förch
Article first published online: 11 JUL 2014 | DOI: 10.1002/ppap.201400016
New approaches towards the quantification of amine groups in the presence of hydroxyl groups are discussed and demonstrated by experiment for plasma copolymers of allylamine and octadiene before and after aging in air or water.
- Long, Vertically Aligned Single-Walled Carbon Nanotubes from Plasmas: Morpho-Kinetic and Alignment Controls
Gennady Burmaka, Igor B. Denysenko, Kostya (Ken) Ostrikov, Igor Levchenko and Nikolay A. Azarenkov
Article first published online: 8 JUL 2014 | DOI: 10.1002/ppap.201400059
The growth mechanism was clarified and differences between the plasma- and neutral gas-grown carbon nanotubes were explained by using an enhanced large-scale model and numerical simulation technique. The nanotubes synthesized by plasma process can be longer than those synthesized by neutral gas technique. The low-temperature growth of the nanotube array is also possible when the hydrocarbon ion flux to the nanotubes dominates over fluxes of other species.
- Engineering of Composite Organosilicon Thin Films with Embedded Silver Nanoparticles via Atmospheric Pressure Plasma Process for Antibacterial Activity
Xiaolong Deng, Christophe Leys, Danijela Vujosevic, Vineta Vuksanovic, Uros Cvelbar, Nathalie De Geyter, Rino Morent and Anton Nikiforov
Article first published online: 3 JUL 2014 | DOI: 10.1002/ppap.201400042
Ag nanoparticles contained nanocomposite thin films can be deposited in a single-step through an atmospheric pressure plasma process. It is shown that the morphology and stoichiometry of the thin films can be controlled by the plasma parameters and the introduced Ag nanoparticles. Further antibacterial tests indicate the effective antibacterial activity of the films against Escherichia coli and Staphylococcus aureus strains.
