“…After film deposition, more than one behavior is observed in relation to surface roughness. Thin coatings applied to smooth glass surfaces exhibit similar behavior, [71][72][73] as observed in this work, decreasing the mean nanometric roughness values (R a = 2 nm) of the surface in relation to the substrate (R a = 4 nm). In the microscale roughness, there was no significant difference in the R a values.…”

This work aims to evaluate the characterization, antibacterial activity, and mesenchymal stem cell (MSC) viability in films obtained by cold plasma polymerization, from the essential oil of Eucalyptus globulus on Ti6Al4V alloy. The film presented low roughness values and a contact angle of 85°. The process incorporated a coating with oxygenated functional groups (OH and C═O). The effect of ultraviolet radiation, ethylene oxide, autoclave, and air plasma sterilization on polymer degradation was evaluated. Biofilm formation by Staphylococcus aureus was reduced on the film surface with no toxicity to MSCs. These effects can be attributed to functional groups, combined with the surface roughness and contact angle. These results suggest a potential for the application of this coating in biomaterials.

“…They have been made into bactericidal polymer coatings using radiofrequency PECVD (RF-PECVD) in continuous or pulsed plasma modes at room temperature. 115 The bactericidal properties of the coatings were evaluated by fluorescence imaging with a LIVE/DEAD bacterial viability kit. After 18 h of incubation, the coating synthesized using pulsed plasma with power of 50 W eliminated >99% of P. aeruginosa and ∼20% of S. aureus in contact.…”

Biofouling is a major issue across various industries ranging from healthcare to the production of food and water and transportation. Biofouling is often induced or mediated by environmental microbes, such as bacteria. Therefore, developing antibacterial coatings has been an essential focus of recent research on functional polymer thin films. To achieve high film quality, vapor-phase techniques represent promising alternatives to traditional solution-based methods, especially for the design and synthesis of antibacterial polymer coatings, as they enable highly uniform, chemically precise, and substrate-independent coatings. This Perspective examines the potential of vapor-phase polymerization techniques to create novel antibacterial polymer coatings. Current advancements in the design of antifouling, bactericidal, antibiofilm, and multifunctional coatings via vapor-phase techniques are organized based on their action mechanisms and design principles. The opportunities and challenges associated with implementing vapor-phase polymerization for developing antibacterial coatings are highlighted.

“…The plasma polymers showed antibacterial activity against S. aureus and P. aeruginosa whilst supporting human dermal fibroplast adhesion. [94] Considering essential oil-based plasma polymers, it is important to remember that essential oils are natural products whose composition may vary from batch to batch. Results from different research works can therefore not be easily compared and may not always be entirely reproducible with materials from different suppliers or batches.…”

Plasma‐enhanced chemical vapor deposition is a highly promising tool for coating deposition due to its versatility, tunability, low chemical consumption, and cost‐effectiveness, with an increasing scope of deposition methods at both low and atmospheric pressure. Adhering to green chemistry principles, biobased precursors have recently shifted into the focus of research interests. This review gives an overview of the main biogenic substance classes that have been used for the deposition of plasma polymer coatings, including natural oils, terpenes, enzymes, and lactic acid‐based precursors. The common feature of these precursors is not only their biogenic origin, but additionally the manifold properties of the resulting plasma‐deposited thin films, ranging from antimicrobial properties to tunable surface‐wetting characteristics, electrical conductivity, or biodegradability. This combination of unique features makes plasma‐derived polymers based on natural precursors immensely attractive for manifold applications.
