“…According to this data, very low input specific energies (less than 0.06 kJ · cm −3 ), did not have a significant effect on the surface chemistry of ppOD coatings. This was expected since lower W / F values generate charged species with smaller kinetic energies . In such low energy plasma, OD monomer molecules cannot be sufficiently fragmented and consequently less hydrocarbon functionalities are deposited on the surface.…”

1,7-Octadiene (OD) was plasma polymerised onto silicon wafers and glass slides under a broad range of input specific energies and deposition times to study the hydrophobicity of deposited films. Deposition of plasma polymerised 1,7-octadiene (ppOD) film resulted in decrease of glass slide surface free energy (SFE) from %71 to 44 mJ Á m À2 . X-ray photoelectron spectroscopy (XPS) and time of flight secondary ion mass spectroscopy (ToF-SIMS) results confirmed that this decrease is due to the concealing of polar -Si-OH groups by non-polar -C x H y functionalities. Atomic force microscopy (AFM) images along with ToF-SIMS spectra suggested patchy-like growth of ppOD films in the very early stages of polymerisation. It has been demonstrated that a precise control over the surface hydrophobicity is achieved by simply tuning the plasma polymerisation parameters.

“…Thus, methods to provide roughness to solid surfaces have been developed [8][9][10][11][12][13][14][15][16][17]. Many fabrication methods had been employed to fabricate the UWR surfaces [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37].…”

Ultra-water-repellent (UWR) films were prepared by microwave plasma-enhanced chemical vapour deposition using trimethylmethoxysilane and aluminium (III) diisopropoxide ethylacetoacetate (ADE) as raw materials. The film was mainly composed of silica and alumina and was apparently transparent. The film thickness was approximately 500 nm. The sample surface was treated with an organosilane in order to introduce hydrophobic groups. The hydrophobic modification led to a water contact angle of more than 150°, whose value corresponds to the UWR surface. The hardness of film with an optimized Al content was significantly improved compared with that without Al. The maximum hardness was 1.71 GPa. In consequence, we successfully prepared an UWR film in the silica–alumina system.

“…Organosilicon are also selected for the protection of metals from corrosion (Fracassi et al 2003). The most employed organo-silicon monomers include TetraMethylDiSilOxane (TMDSO) (Deng et al 2015), TetraMethylSilane (TMS) (Fonseca et al 1993), VinylTriMethylSilane (VTMS) (Bonnar et al 1999), HexaMethylDiSilOxane (HMDSO) (Morent et al 2009), and HexaMethylDiSilaZane (HMDSZ) (Huang et al 2015) containing Si, H, C, O, or N atoms (Gaur and Vergason 2000). Organo-silicon monomers are used in industries because they are non-toxic components and they do not generate harmful species during processing.…”

Environmental conditions in food and medical fields enable the bacteria to attach and grow on surfaces leading to resistant bacterial biofilm formation. Indeed, the first step in biofilm formation is the bacterial irreversible adhesion. Controlling and inhibiting this adhesion is a passive approach to fight against biofilm development. This strategy is an interesting path in the inhibition of biofilm formation since it targets the first step of biofilm development. Those pathogenic structures are responsible for several foodborne diseases and nosocomial infections. Therefore, to face this public health threat, researchers employed cold plasma technologies in coating development. In this review, the different factors influencing the bacterial adhesion to a substrate are outlined. The goal is to present the passive coating strategies aiming to prevent biofilm formation via cold plasma treatments, highlighting antiadhesive elaborated surfaces. General aspects of surface treatment, including physico-chemical modification and application of cold plasma technologies, were also presented. Key points • Factors surrounding pathogenic bacteria influence biofilm development. • Controlling bacterial adhesion prevents biofilm formation.• Materials can be coated via cold plasma to inhibit bacterial adhesion.
