“…To demonstrate the potentiality of atmospheric‐pressure plasma to promote the oxidative polymerization of EDOT (Figure a) to PEDOT (Figure b), a series of thin films were prepared from the AP‐DBD reaction of EDOT using different plasma gas compositions. The selected AP‐DBD setup depicted in Figure affords a dry, single‐step, and up‐scalable solution for thin film deposition . Due to the rather low vapor pressure of EDOT, its use in atmospheric‐pressure CVD implies the use of evaporating or nebulizing systems .…”

A simple and easily scalable approach toward the simultaneous synthesis and deposition of conducting plasma-polymerized 3,4-ethylenedioxythiophene (ppE-DOT) coatings is reported. Our atmospheric-pressure dielectric barrier discharge (AP-DBD) approach, operating at room-temperature and atmospheric-pressure, does not involve the use of oxidants other than the reactive oxygen species (ROS) formed by the open air Ar/O 2 dielectric barrier discharge. The oxidative polymerization of EDOT is confirmed using UV-visible (UV-vis), Raman, and Fourier-transform infrared (FTIR) spectroscopy. High-resolution mass spectrometry (HRMS) investigations highlight the discrepancies between the synthesized ppEDOT and conventional PEDOT. Finally, highly transparent (i.e., 98% transmittance) and durable conducting thin films are deposited on polyethylene naphthalate (PEN) foils.

Defect engineering in photocatalysts recently exhibits promising performances in solar-energy-driven reactions. However, defect engineering techniques developed so far rely on complicated synthesis processes and harsh experimental conditions, which seriously hinder its practical applications. In this work, we demonstrated a facile mass-production approach to synthesize gray titania with engineered surface defects. This technique just requires a simple liquid-plasma treatment under low temperature and atmospheric pressure. The in situ generation of hydrogen atoms caused by liquid plasma is responsible for hydrogenation of TiO 2 . Electron paramagnetic resonance (EPR) measurements confirm the existence of surface oxygen vacancies and Ti 3+ species in gray TiO 2−x . Both kinds of defects concentrations are well controllable and increase with the output plasma power. UV-Vis diffused reflectance spectra show that the bandgap of gray TiO 2−x is 2.9 eV. Due to its extended visible-light absorption and engineered surface defects, gray TiO 2−x exhibits superior visible-light photoactivity. Rhodamine B was used to evaluate the visible-light photodegradation performance, which shows that the removal rate constant of gray TiO 2−x reaches 0.126 min −1 and is 6.5 times of P25 TiO 2 . The surface defects produced by liquid-plasma hydrogenation are proved stable in air and water and could be a candidate hydrogenation strategy for other photocatalysts.Nanomaterials 2020, 10, 342 2 of 13 light absorption, prompting superior performances in photodegradation and water splitting [13][14][15]. The enhanced solar light absorption of black TiO 2 is ascribed to additional intermediate electronic states (e.g., V o or Ti 3+ states) and disorder surface caused by hydrogenation [16][17][18]. More importantly, defect engineering, for instance defects concentration and distribution, also plays an important role in tuning photocatalytic activity of black TiO 2 . It was reported that the high defect ratio of surface to bulk can significantly enhance the photoactivity owing to preferential diffusion from bulk to surface of photoinduced charges [19,20]. However, surface defects are not stable enough as it can be spontaneously oxidized in air and water. So far, mainstream strategies to synthesize black/gray TiO 2−x are relied on the reduction of pristine stoichiometric TiO 2 [20][21][22][23][24], such as annealing under high pressures of H 2 or NH 3 , high-energy particle bombardment (hydrogen plasma, laser plasma, or high-energy electrons), and chemical reduction with reducing agent in vacuum. Apparently, it is significant and desirable to develop a simple and feasible strategy for massive production of black/gray TiO 2−x with engineered surface defects and related abundant solar absorption.Hereafter, we conduct a one-pot synthesis of gray TiO 2−x with large solar harvesting and engineered surface defects using a liquid-plasma technology at room temperature and atmospheric pressure [25].

“…AP‐PECVD provides a convenient route toward the preparation of reactive‐functionalized surfaces, including carboxylic acid, epoxy, and amine‐functionalized surfaces . Recently, the range of functionalized surfaces available from an atmospheric plasma deposition process was extended to catechol and quinone‐functionalized layers, thanks to the use of a solid dopamine derivative compound in a LA‐PECVD approach . Catechol and quinone groups, i.e., oxidized catechol, are providing new adhesive and molecules grafting options inspired by the mussels’ feet, which have the ability to strongly adhere to surfaces in harsh conditions .…”

Liquid-assisted plasma-enhanced chemical vapor deposition (LA-PECVD) provides a convenient approach toward the preparation of functional surfaces. In this work, the LA-PECVD approach is reported for the high deposition rate of tuneable catechol and quinonefunctionalized coatings from plasma polymerization of vinyltrimethoxysilane (VTMOS) and dopamine acrylamide (DOA). Most particularly, the influence of the liquid precursor delivery rate and of the plasma power density on the chemistry and morphology of the formed layers are investigated. Precursor delivery rate and plasma power conditions are found, through mass measurement, XPS, FTIR, and Raman spectroscopy, to enable the high deposition rate of cross-linked coatings. Interestingly, the integration and conservation of the catechol functional group from the DOA monomer are highlighted through the reduction of a silver nitrate solution and silver nanoparticles formation observation via SEM/EDX. Due to the presence of oxidant species and to the bombardment of the layer with highly energetic species, quinone groups formation is likely to occur during the plasma treatment and is then highlighted via ToF-SIMS analyses of a surface successfully derivatized with a b-lactamase. The conservation of both functional groups on the surface makes this type of layer promising for numerous applications. Quinone groups provide a real platform for the immobilization of biomolecules with various properties, e.g., antibiotics degradation, antibacterial, while the catechol groups are interesting for trapping radicals or metal ions for water treatment applications.
