“…The working gas was dry compressed air, with a flow rate of 40 standard litres per minute (slm). A stainless steel nozzle (Plasmatreat 10147; 5 mm diameter) was used in this study (it has been shown that the material nozzle could have an influence on the plasma jet chemistry [19]). The precursor was introduced in the plasma using a home-made spraying system based on the Venturi effect fixed to the torch.…”

International audienceA pulsed-arc atmospheric pressure air plasma jet has been used to depositplasma polymerized acrylic acid/methylene-bis-acrylamide (ppAA/MBA) organic thinfilms. Optical emission spectroscopy has been performed to investigate the reactivity of theplasma and the dissociation of the precursor as a function of the pulse frequency anddistance from the nozzle. An estimation of the OH rotational temperature, which is anindicator of the plasma gas temperature, has also been performed. By heating the substrateduring deposition, it was possible to improve to a great extent the stability to water of thecoatings. Stable ppAA/MBA films have been obtained with an air plasma over a largerange of pulsed frequencies (from 15 to 25 kHz) when the substrate was heated to 200° C.The composition of these coatings was investigated by FTIR and different amide/acidratios were obtained, showing the possibility to grow stable films with different functionalgroups by adjusting the deposition parameters

An atmospheric pressure plasma jet (APPJ) sustained by a pulsed atmospheric arc (PAA) transferred on an electrically conducting surface was operated with a mean power of 700 W, a pulse frequency of 60 kHz, and a gas mixture of N2 and H2 with up to 10% H2, flowing at 30 to 70 SLM. It was shown that the plasma bridge ignited between the grounded injector and electrically conducting and floating substrates can be used for electrical grounding. This allowed for arc transfer on such substrates. The plasma bridge was stable for Argon flow through the injector from 3 to 10 SLM. Its length was between 5 and 15 mm. The plasma bridge current was 350 mA. The copper contact pads on an alumina electronic board were treated using the plasma bridge sustained by Ar injection for grounding. First, an oxide film of about 65 nm was grown by a compressed dry air (CDA) plasma jet. Then, this film was reduced at a speed of 4 cm2/s by forming gas 95/5 (95% of N2 and 5% of H2) plasma jet.
