Comparison between wet deposition and plasma deposition of silane coatings on aluminium

Poly(ethylene glycol) Films Deposited by Atmospheric Pressure Plasma Liquid Deposition and Atmospheric Pressure Plasma‐Enhanced Chemical Vapour Deposition: Process, Chemical Composition Analysis and Biocompatibility

“…The system was used directly into air, without any control of the surrounding atmosphere. This set up was already successfully used for the deposition of silane based coatings,10 and for the atmospheric plasma polymerization of polystyrene 11…”

“…Table 1 shows closely related polyethers. Under ordinary conditions, all of them are water insoluble except from PEG and poly(propylene oxide)s with a molecular weight lower than 1 500 Da 10, 15–17. Because plasma‐polymerized films are known to be relatively highly cross‐linked, as pointed out by Biedermann et al,18 their solubility should be strongly reduced.…”

Adhesion Improvement between Epoxy and Stainless Steel Using a Silane Coupling Agent in an Atmospheric Plasma Process

“…The properties and quality of siloxane layers are strongly dependent on the various parameters of the deposition process. [22][23][24] Application of silane coupling agents through wet deposition technique is a widely studied method, however it has some inherent limitations. Firstly, wet deposition technique is a multistep process that requires dedicated substrate pre-treatment to enhance the metal-film bonding and a thermal post treatment for condensation of siloxane film.…”

“…[25] As a consequence, it might be possible that some water or solvent remains in the siloxane film after condensation, decreasing the performance of the siloxane film, like for corrosion protection. [24] Deposition of silane coupling agents using atmospheric plasma chemical vapor deposition could be an efficient and innovative alternative to wet deposition with the advantage of combining plasma cleaning a priori to the deposition in the same reactor. Atmospheric plasmas (AP) are nowadays well known in academics and industries for surface engineering with a dedicated purpose.…”

Evidence of covalent bond formation at the silane–metal interface during plasma polymerization of bis-1,2-(triethoxysilyl)ethane (BTSE) on aluminium

“…The entire gas stream was directed onto a substrate located 0.5 cm downstream. This set up was already successfully used for the deposition of silane based coatings [11] and for the atmospheric plasma polymerization of poly(ethylene glycol) (PEG) [12] and polystyrene [13].…”
