“…Owing to the well-understood plasma chemistry of HMDSO related to plasma-state polymerization, HMDSO might be used as a model monomer to investigate the characteristics of plasma reactors as illustrated above. Besides HMDSO, a variety of further monomers for PP can be evaluated based on the discussed macroscopic approach [150,[170][171][172][173][174][175][176]. A detailed analysis gives hints on the reaction mechanism and allows for the differentiation between the gas phase and surface processes.…”

Since decades, the PECVD (“Plasma Enhanced Chemical Vapor Deposition”) processes have emerged as one of the most convenient and versatile approaches to synthesizing either organic or inorganic thin films on many types of substrates, including complex shapes. As a consequence, PECVD is today utilized in many fields of application such as microelectronic circuit fabrication, optics/photonics, biotechnology, energy, smart textiles, and many others. Nevertheless, owing to the complexity of the process including numerous gas phase and surface reactions, the fabrication of tailor-made materials for a given application is still a major challenge in the field making it obvious that the mastery of the technique can only be achieved through the fundamental understanding of the chemical and physical phenomena involved in the film formation.In this context, the aim of this foundation paper is to share with the readers our perception and understanding of the basic principles behind the formation of PECVD layers considering the co-existence of different reaction pathways that can be tailored by controlling the energy dissipated in the gas phase and/or at the growing surface. We demonstrate that the key parameters controlling the functional properties of the PECVD films are similar whether they are inorganic or organic-like (plasma polymers) in nature, thus supporting a unified description of the PECVD process. Several concrete examples of the gas phase processes and the film behavior illustrate our vision.To complete the document, we also discuss the present and future trends in the development of the PECVD processes and provide examples of important industrial applications using this powerful and versatile technology.

“…However, to the best of our knowledge, no study reports on the controlled formation of a coating made of nanoparticles and a coating made of a smooth polymer thin film (free of any nanoparticle) during a single deposition run, simply by changing the sample position within the reactor and finely tuning the plasma pulse times. Complementary to a former study recently published, [ 20 ] pulsed plasma polymerization was investigated here in a one‐meter‐long tubular plasma reactor using maleic anhydride as a precursor. This configuration allowed work to be carried out in the discharge zone or very far away from it.…”

The properties of the final product resulting from plasma polymerization strongly depend on the operating conditions and they impact the final application of the plasma polymer coating. Low-pressure pulsed plasma polymerization of maleic anhydride was investigated at two different positions in relation to the glow discharge in a 1-m-long tubular reactor. Interestingly, competition was observed in the deposition of maleic anhydride plasma polymer in the form of a smooth thin film versus that in the form of nanoparticles. The possibility of a spatiotemporal control of plasma polymerization enabled the deposition of a plasma coating with tunable morphological properties depending on the sample position from the glow discharge and on the plasma pulse parameters (on-time and off-time).

“…For instance, it is known that performing plasma polymerization in the post-discharge zone (also known as remote plasma deposition) limits the crosslinking of plasma polymers since fewer ions are found far from the glow discharge, thus leading to spatial control of plasma polymerization [29]. Consequently, the composition of the plasma discharge depends on a multitude of parameters, such as the power supplied by the electromagnetic wave generator, the pressure in the reactor, and the temporal and spatial parameters of the discharge [30,31].…”

The plasma polymerization of hexamethyldisiloxane (HMDSO) leads to the environmentally friendly fabrication of water-repellent coatings through a vapor-phase surface functionalization process using alternatives to the controversial perfluoroacrylate precursors. However, the durability of these coatings is their Achilles’ heel, which requires an in-depth study of the relationship between the structure and properties of these thin films in order to propose concrete solutions for the fabrication of fluorine-free water-repellent textiles. In this context, HMDSO plasma polymers have been deposited on cotton fabrics in an original reactor that allows easy tuning of temporal and spatial parameters of the glow discharge. The functionalized fabrics were characterized to gain insights into the chemical composition of the coatings, their morphology and, above all, their adhesion properties. Interestingly, the results after washing tests revealed a significant dependence of the durability of the superhydrophobic property on the elastic modulus of the deposited polymer. The formation of some radicals at the substrate–thin film interface in the early stages of deposition also correlates with some results. These relationships between the operating conditions of the plasma polymerization, the interfacial properties and the performances of the functionalized fabrics, but also the characterization methodology developed in this work, can undoubtedly serve the engineering of water-repellent fluorine-free coatings on fabrics with optimal durability.
