“…These results are in good agreement with the evolution of the CNT component of the C1s peak (C1 = 285.6 eV; C–N), which strongly increases for C–N. This result can be explained by simultaneous action of the ammonification during the post‐treatment on CNT, which may reduce the impure amorphous carbon and improve the CNT quality . We demonstrated that the ammonia post‐treatment can strongly affect the surface modification on CNT, even if a lateral growth of the CNT is obtained.…”

“…Plasma post‐treatment by using H 2 , O 2 , or Ar gas has sometimes been performed on the surface of the nanomaterials to reduce the contamination . It is suggested in our previous work that the surface performances can be modified by ammonia plasma . Moreover, ammonia is used for providing hydrogen ions to passivate the surface and reduce the dangling bond density on the surface of materials, such as low‐k, SiC, and polymer .…”

We present horizontally-oriented multiwalled carbon nanotubes (CNTs) grown by means of thermal chemical vapor deposition. The CNT is across the trenches of the catalytic metals on predefined Ti electrodes. The properties of the lateral multiwalled CNT, following post-ammonia plasma treatment, are reported. Information about the ammonia plasma treated on the interface structure of CNT is obtained using X-ray photoelectron spectroscopy. The experimental results show that upon exposure to ammonia, the electrical property of the CNT is found to increase.

Front Cover: Two diff erent atmospheric pressure non-thermal plasmas have been used to clean the surface of a corroded 19 th century daguerreotype. The fi gures on top show the fi gure visage untreated; after 2 nd plasma-jet treatment on the left half-side only; and after DBD-plasma treatment of the right half-side too. The fi gures at the bottom show optical micrographies in white light of the woman's eye on the left daguerreotype portion in (a) untreated conditions and (b) after plasma-jet treatment. Further details can be found in the article by M. Boselli et al. on 1600027. Feature Article In this work, the eff ect of T substrate on the plasma deposition kinetics and thermal properties of pdMMA fi lms is assessed. A plasma deposition mechanism is proposed, based on the adsorption/desorption equilibrium of activated species, followed by a surface plasma polymerization. A decreased volatile fraction and enhanced cross-link density with increasing T substrate is shown by TG analysis. In accordance , DSC analysis confi rms an increasing glass transition. Plasma polymers and electrospray-ionization (ESI) polymer layers are compared for most ef-fi cient adhesion promotion in carbon fi ber-epoxy resin composites. Diff erences in chemical structure and composition of polymer layers are discussed as well as the surface topography of these nanometer thick fi lms.

“…Various approaches have been applied to improve the bonding behavior of the fibers 5–20. Among the methods reported, plasma treatment is considered as a clean and effective method to modify the surface of the fibers 11–20. In this study, cold plasma treatment was used to modify the surface of the hybrid PTFE/Kevlar fabric and its effect on the tribological properties of the hybrid PTFE/Kevlar fabric composite was investigated in detail.…”

Hybrid PTFE/Kevlar fabric was surfacemodified by air plasma to improve the adhesion to phenolic resin. The tribological properties of fabric composite with or without plasma-treated hybrid PTFE/Kevlar fabric were investigated in detail. Friction and wear tests showed that friction-reducing and antiwear ability of hybrid PTFE/Kevlar fabric composite were remarkably improved after plasma treatment. Scanning electron microscopy and X-ray photoelectron spectroscopy results indicated that the fiber surfaces were etched and the contents of oxygen and nitrogen increased after plasma treatment, which was favorable for improved fiber/resin bonding strength. The enhancement contributed to the improved tribological properties of hybrid PTFE/Kevlar fabric composite after plasma treatment.
