“…Recently, a growing interest for multifunctional coatings has appeared with the development of nanocomposites thin films that consist of NPs embedded in a matrix. The presence of NPs provides the nanocomposite with extra properties related to their interactions with the matrix . In the literature, two approaches exist for synthesizing nanocomposite thin films using atmospheric pressure DBDs.…”

“…The presence of NPs provides the nanocomposite with extra properties related to their interactions with the matrix. [19][20][21][22] In the literature, two approaches exist for synthesizing nanocomposite thin films using atmospheric pressure DBDs. One consists in using two different precursors, one to create the NPs and the other to deposit the host matrix.…”

The synthesis of composites thin films made by injecting an aerosol suspension of 20 nm‐size TiO2 nanoparticles (NPs) and isopropanol (IPA) in a filamentary argon Dielectric Barrier Discharge (DBD) is studied as a function of the DBD frequency from 1 to 50 kHz. The plasma is modulated to get homogeneous coatings. The deposition rate and morphology of the composite thin films are determined from SEM images of both surface and cross section. Their chemical composition is investigated by XPS, Raman spectroscopy and FTIR measurements. The structural composition of the NPs is examined by XRD. All the deposited composites show the chemical signature of the NPs as well as of the polymer‐like coating resulting from the plasma polymerization of IPA. No mixed phase is observed and the sizes of the NPs as well as of their aggregates are not affected by the plasma. With this method aerosol droplets are evaporated before entering the plasma and the NPs inside a same droplet are aggregated. Results show that the DBD frequency controls the composite composition by independently influencing the NPs transport and the matrix growth rate. At 1 kHz, the coating is essentially made of NPs with a low carbon coating. From 1 to 50 kHz, the Ti/C ratio is divided by two orders of magnitude. As the frequency increases the quantity of NPs decreases and since 10 kHz the matrix thickness increases. The decrease of the NPs is explained by the numerical modeling of the NPs trajectory. It is found that from 10 to 1 kHz, the lower is the frequency, the higher is the transport of the NPs to the surface due to the electrostatic force. On the other hand the matrix growth rate increases from almost zero at 10 kHz up to 19 nm · min−1 at 50 kHz because of the linear increases of the DBD power with the frequency.

“…For inorganic matrix, such as metal matrix or alloy matrix, these nanocomposite coatings could be prepared by various methods, including chemical vapor deposition (CVD) (see Figure 3), powder metallurgy, physical vapor deposition (PVD) [41][42][43][44][45], thermal plasma spray [46][47][48], sol-gel [49][50][51][52] (see Figure 1), epitaxial growth [53], cold spray [54][55][56][57][58][59][60][61] (see Figure 2), and electrodeposition [62][63][64][65][66][67]. Metal matrix composite coatings that dispersed a second phase [68,69] have attracted extensive attention owing to unique properties such as oxidation and corrosion resistance [69,70], wear resistance [71,72], and magnetic properties [72].…”

Incorporation of nanofillers into the organic coatings might enhance their barrier performance, by decreasing the porosity and zigzagging the diffusion path for deleterious species. Thus, the coatings containing nanofillers are expected to have significant barrier properties for corrosion protection and reduce the trend for the coating to blister or delaminate. On the other hand, high hardness could be obtained for metallic coatings by producing the hard nanocrystalline phases within a metallic matrix. This article presents a review on recent development of nanocomposite coatings, providing an overview of nanocomposite coatings in various aspects dealing with the classification, preparative method, the nanocomposite coating properties, and characterization methods. It covers potential applications in areas such as the anticorrosion, antiwear, superhydrophobic area, self-cleaning, antifouling/antibacterial area, and electronics. Finally, conclusion and future trends will be also reported.

“…The dielectric barrier discharge (DBD) configuration [1,2] that enables the creation of nonthermal plasmas at atmo spheric pressure has gained increasing interest in the past years, with applications in surface functionalization [3], synthesis of homogeneous or nanostructured thin films [4][5][6][7][8], removal UPR 8521, of pollutants [9], disinfection of medical tools [10], as well as tissue sterilization [11] and solar cells production [12] to name only a few. Despite the fact that DBDs are nowadays part of several industrial processes, the nature of the excited species that they contain and the mech anisms by which they interact with material surfaces still has to be understood.…”

This article describes the occurrence of a phenomenon that is observed while recording midinfrared (4000-700 cm −1) absorption spectra of dielectric barrier discharges sustained at frequencies ranging from 300 Hz to 15 kHz. This phenomenon is observed as the presence of very sharp spikes in the spectrum, for which the wavenumber depends on both the high voltage frequency used to generate the discharge and the velocity of the moving mirror of the interferometer (which in turn determines the interferogram sampling frequency). While it is well known that the consumption of gas precursor within plasmas can be followed, we demonstrate that Fourier transform infrared spectroscopy also makes it possible to monitor frequencies and coupling of excitation mechanisms occurring in the plasma.
