“…This could be similar to results described in the reference where the high reactivity of propargyl methacrylate in the gas phase is assumed to lead to powder formation in the gas phase and thus to promote the deposition of coatings with stacked globular features whose diameter is in the range of 50–100 nm. This submicrometric structure in thin coatings is particularly interesting when very hydrophobic to superhydrophobic coatings are targeted …”

Coatings have been deposited from acrylates and methacrylates mixtures by means of an aerosol assisted atmospheric plasma process. The reference coating precursor is dodecyl acrylate (DOCA). In order to improve the coatings mechanical properties, one diacrylate and one dimethacrylate are added to DOCA in the precursor mixture. It is expected that they act as cross‐linking agents, thus modifying the coatings macromolecular structure and improving the coating mechanical properties. The influence of cross‐linkers concentration on the coatings properties is investigated. An improvement of coatings scratch resistance when the concentration of cross‐linkers increases in the mixture is observed, but the effect on coatings structure is different between the diacrylate and the dimethacrylate.

“…[ 73 ] More details about the method of depositing a series of coatings made from different concentrations of DOCA and PFDA precursors (monomers) is described by Mertz et al. [ 36 ] In short, a plasma polymer coating with a low level of precursor fragmentation is deposited from a mixture of DOCA and PFDA. The hydrophobic character of the coating increases with the ratio of PFDA in the precursor mixture, as well as its roughness amplitude and complexity, thereby providing a coating whose wettability is ranging from hydrophobic (pure DOCA) to superhydrophobic (pure PFDA).…”

“…Evolution of their amounts with the ratio of PFDA and DOCA amounts injected in the plasma chamber during the polymerization is described and discussed elsewhere. [ 36 ] It also allowed us to calculate the actual amount of PFDA (%PFDA) on the topmost surface of each coating as described in the Experimental Section. Based on the results, coatings were categorized into six classes of %PDFA ( Table 2 ): 0% (ppPFDA0, i.e., ppDOCA); from 20% to 39% (ppPFDA20–39), from 40 to 59% (ppPFDA40–59); from 60% to 79% (ppPFDA60–79); %PFDA from 80 to 99% (ppPFDA80–99); 100% (ppPFDA100, i.e., ppPFDA).…”

“…The investigation was conducted on a range of coatings with increasing hydrophobic, to superhydrophobic, deposited by plasma polymerization as previously described. [ 36 ] The coatings are manufactured in high series by an adequate process easy to transfer to the industry. Surface properties were thoroughly investigated by X‐ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and dynamic water contact angle measurements.…”

or food industry materials. [2-6] The initial events of biofilm formation include bacterial attachment to surface. This attachment depends on the environmental conditions (bacterial species, medium, temperature, etc) and on the material surface properties. Chemical composition, topography, mechanical properties as well as wettability (hydrophobicity and hydrophilicity), surface energy, and charge are the surface-related factors known to influence bacterial adhesion and biofilm development. [7,8] Some of them are specially examined for their great potential to create antibiofilm surfaces. [9] Surface energy is one of the factors involved in bacterial attachment. [10-13] More particularly, low-wettable especially superhydrophobic surfaces demonstrated some promising potential to reduce surface colonization by bacteria. [14-19] This prevention may be the result of reduced protein adsorption and entrapped air layer between the bacterial suspension and the surface [14,20-22] However, contradictory results are reported. [23,24] Aside from high differences in nature and wettability of the surfaces used in these studies, a serious reason is the common confusion regarding the distinction between bacterial retention and adhesion. Indeed, in Effect of surface low-wettability on bacterial colonization has become a prominent subject for the development of antibacterial coatings. However, bacteria's fate on such surfaces immersed in liquid as well as causal factors is poorly understood. This question is addressed by using a range of coatings with increasing hydrophobicity, to superhydrophobic, obtained by an atmospheric plasma polymer method allowing series production. Chemistry, wettability, and topography are thoroughly described, as well as bacterial colonization by in situ live imaging up to 24 h culture time in different liquid media. In the extreme case of superhydrophobic coating, substrates are significantly less colonized in biomolecule-poor liquids and for short-term culture only. Complex statistical analysis demonstrates that bacterial colonization on these low-wettable substrates is predominantly controlled by the culture conditions and only secondary by topographic coating's properties (variation in surface structuration with almost constant mean height). Wettability is less responsible for bacterial colonization reduction in these conditions, but allows the coatings to preserve colonization-prevention properties in nutritive media when topography is masked by fouling. Even after long-term culture in rich medium, many large places of the superhydrophobic coating are completely free of bacteria in relation to their capacity to preserve air trapping.

Atmospheric pressure plasma allows for the easy modification of materials’ surfaces for a wide range of technological applications. Coupling the aerosol injection of precursors with atmospheric pressure plasma largely extends the versatility of this kind of process; in fact solid and, in general, scarcely volatile precursors can be delivered to the plasma, extending the variety of chemical pathways to surface modification. This review provides an overview of the state of the art of aerosol-assisted atmospheric pressure plasma deposition. Advantages (many), and drawbacks (few) will be illustrated, as well as hints as to the correct coupling of the atomization source with the plasma to obtain specific coatings. In particular, the deposition of different organic, hybrid inorganic–organic and bioactive nanocomposite coatings will be discussed. Finally, it will be shown that, in particular cases, unique core–shell nanocapsules can be obtained.
