“…For the case of other geometries, Sneddon's model [71] and Oliver-Pharr model [69] are reported. The use of PeakForce Quantitative Nanomechanical Mapping (PF-QNM®, Bruker) [38] and nanoDMA [72,73] have been also reported. The latter allows the determination of the storage and loss moduli and consequently of loss factor.…”

Mechanical properties of plasma polymer films: a review

et al. 2021

Plasma polymers are micro-, or more commonly, nano-sized coatings that can be deposited on a variety of substrates through different approaches. The versatility of these polymers is incremented by the possibility to use other precursors than conventional polymerization reactions and by potential changes in the polymerization mechanisms according to the intrinsic physical and chemical properties of the plasma. That flexibility offers a fruitful ground to a great range of scientific and engineering fields, but it also brings many challenges for universalization of empirical observations. In this review, the use of different precursors, substrates and changes in plasma external parameters were evaluated as common, but not necessarily ideal nor exhaustive, variables for the analysis of mechanical properties of plasma polymer films. The commonly reported trends are complemented with the exceptions, and a variety of hypothesis drawn by the empirical observations are shown. The techniques and methods used for determining the mechanical properties of plasma polymers, the effect of post-treatments on them and some applications are evaluated. Finally, a general conclusion highlighting the challenges of the field is provided. Article highlights The mechanical properties of plasma polymers are evaluated as a function of selected parameters. The techniques of characterization of mechanical properties of plasma polymers are summarized. A discussion of future and current demands for the analysis of mechanical properties of plasma polymers is done.

“…The results showed that cell adhesion was favored in stiffer surfaces ( ∼ 120 MPa) when compared to softer ones ( ∼ 0.5 MPa). In recent works, plasma thin films with antibiofouling and antibacterial properties were shown to present excellent scratch and delamination resistance with polymer-like viscoelastic character [72,73].…”

“…During the cleaning process, the high energy plasma level disrupted the structure of organic substances contaminating the material and removed impurities from the surface [130]. Plasma is also used in the industrial production of nanomaterials [131,132] and synthesis and application of thin coatings [133][134][135].…”

Sustainable and organic plant production uses natural products and natural self-regulation processes occurring in the ecosystem. The awareness is growing and the demands of consumers are higher and higher. One solution is to use various methods, as an alternative to pesticides. It is also very important to care for the stored crops after harvesting especially using non-chemical methods. The physical method of plant protection consists in treating the harmful organism with physical factors such as temperature, its same light and radiation, controlled atmosphere, special packaging, pressure, various sounds, ozone, and low-temperature plasma. The availability of effective application techniques opens up new possibilities for the storage of crops in order to maintain their health and quality for a long time. This review focuses on the analysis of physical methods of postharvest protection, especially the latest methods using ozone and low-temperature plasma. As a result, consumers of agricultural crops will be able to consume food free of insects, mycotoxins and pesticide residues.

“…In our previous studies, POx thin coatings were deposited on glass substrates using plasma polymerization with 2-methyl-2-oxazoline or 2-ethyl-2-oxazoline vapor as a monomer [ 13 , 14 ]. The plasma polymerization was performed by means of dielectric barrier discharge burning in nitrogen at atmospheric pressure.…”

Antibacterial coatings on biomedical instruments are of great interest because they can suppress bacterial colonization on these instruments. In this study, antibacterial polymeric thin coatings were deposited on teflon substrates using atmospheric pressure plasma polymerization from a propane–butane mixture. The plasma polymerization was performed by means of surface dielectric barrier discharge burning in nitrogen at atmospheric pressure. The chemical composition of plasma polymerized propane–butane films was studied by energy-dispersive X-ray spectroscopy (EDX) and FTIR. The film surface properties were studied by SEM and by surface energy measurement. The EDX analysis showed that the films consisted of carbon, nitrogen and oxygen from ambient air. The FTIR analysis confirmed, in particular, the presence of alkyl, nitrile, acetylene, imide and amine groups. The deposited films were hydrophilic with a water contact angle in the range of 13–23∘. The thin film deposited samples were highly active against both S. aureus and E. coli strains in general. On the other hand, the films were cytocompatible, reaching more than 80% of the cell viability threshold compared to reference polystyrene tissue.
