The reactivity of deuterated water vapors with PE films, modified by an atmospheric Ar-D2O post-discharge, is traced both at the polymer surface and along the depth, by using static and dynamic time-of-flight secondary ion mass spectrometry. The dependences of the oxidative functionalization on the time of treatment and the gap between sample and plasma source are elucidated in order to tune the chemical and structural modifications of the outermost polymer layers.

Systematic optical emission spectroscopy measurements of a non-thermal atmospheric pressure DC plasma have been performed in order to get insight into the different species in the plasma. The plasma was ignited in pure nitrogen, while copper was introduced via a target electrode. This work is a first step towards a thorough understanding of this special type of copper containing nitrogen plasma at atmospheric pressure for the deposition of copper oxide films.

A simple plasma system consists of aluminum electrodes, flakes, and ultrapure water, which uses no chemical, and generates no waste with high recyclability for the synthesis of aluminum oxide powder. Such green synthesis has a significantly lower environment impact than conventional synthesis processes.

Transparent organosilicate protective bilayer coatings on poly methyl methacrylate (PMMA) substrates are deposited using atmospheric plasma deposition in ambient air with different carbon bridge precursors. The bottom adhesive layer was a hybrid organosilicate adhesive layer deposited using different carbon chain length precursors or accompanied with a ring structure 1,5-cyclooctadiene (CYC) precursor. The top layer is a dense silica coating with high elastic modulus and hardness deposited with only carbon bridge precursor. The deposited bilayer structure showed unique properties as ∼100% transparency in the visible light wavelength region, approximately three times the adhesion energy and four times the Young's modulus of commercial polysiloxane sol–gel coatings.
