Effect of dopants and DBD plasma treatment on the conductivity of fabrics impre...

Conductive properties are paving the way to produce smart textiles with a robust framework, so the development of electroconductive textiles is an area with growing interest. Poly (3,4-ethylene dioxythiophene):polystyrene sulfonate (PEDOT:PSS), is a conductive polymer widely used to impart conductivity to textiles. An increase of the conductivities is possible through the addition of secondary dopants to the co...

Imidazolium salt and dielectric barrier discharge plasma treatment to enhance t...

Conductive textiles are a class of materials with a growing interest due to their potential applications in medical, healthcare, comfort, protective clothing, and sportswear sectors. They can be used for the development of smart textiles able to answer to different external stimuli such as thermal, mechanical, chemical, electrical, magnetic, and optical. The complex poly (3,4-ethylene dioxythiophene):polystyren...

Atmospheric-pressure plasma spray deposition of silver/HMDSO nanocomposite on p...

Novel coatings containing silver nanoparticles (AgNPs) with strong bonding and controllable antibacterial activity on polyamide 6,6 fabric were produced by dielectric barrier discharge (DBD) plasmaassisted deposition at atmospheric pressure and hexamethyldisiloxane (HMDSO) layers. Silver ion release was tuned using a “sandwich” coating structure to prolong the antibacterial effect. The novel spray-assisted depo...

DBD plasma treatment and chitosan layers - A green method for stabilization of ...

The addition of silver nanoparticles (AgNPs) to biomedical textiles can be of great interest to protect the materials against microorganisms and prevent their spread. However, the human and environmental over‐exposure to AgNPs is leading to numerous concerns due to their toxicity. In this work, AgNPs were stabilized onto polyamide 6.6 fabrics (PA66) through atmospheric dielectric barrier discharge (DBD) plasma ...

Antimicrobial efficacy of low concentration PVP-silver nanoparticles deposited ...

In this study, a low concentration (10 μg·mL−1) of poly(N-vinylpyrrolidone) (PVP)-coated silver nanoparticles (AgNPs) were deposited by spray and exhaustion (30, 70 and 100 ◦C) methods onto untreated and dielectric barrier discharge (DBD) plasma-treated polyamide 6,6 (PA66) fabric. DBD plasma-treated samples showed higher AgNP deposition than untreated ones for all methods. After five washing cycles, only DBD p...

Efficient silver nanoparticles deposition method on DBD plasma-treated polyamid...

Several methods for silver nanoparticles (AgNPs) deposition on dielectric barrier discharge (DBD) plasma treated and not treated polyamide 6,6 fabric were tested for the production of durable antibacterial textiles. Ultrasound-assisted, dip-coating, exhaustion at 70 ̊C and spray deposition methods were applied. The treated fabrics were analysed in terms of coating uniformity, plasma effect, nanoparticles concen...

Atmospheric pressure plasma and depositions of antibacterial coatings

Healthcare-associated infections (HCAI) are complications of healthcare that result in elevated patient morbidity and mortality. HCAI present a huge financial burden for patients, hospitals and insurers due to extended hospitalisation and associated care. According to the estimations, in the US alone, HCAI affects approximately 2 million patients annually, of whom approximately 90.000 patients die, with an esti...

Efficient silver nanoparticles deposition method on DBD plasma-treated polyamid...

The study of antimicrobial fabrics with silver nanoparticles (AgNPs) incorporation has shown excellent properties in medical, pharmaceutical, cosmetics and electronics applications due to their formidable action against pathogens, preventing and treating infections.[1] The high surface-to-volume ratio from AgNPs promotes an easy release of silver ion, responsible for the antimicrobial effect.[2] The most tradit...

Antibacterial nanocomposites based on Ag NPs and HMDSO deposited by atmospheric...

The development of new multifunctional coatings with antimicrobial properties has a special interest in several applications for pharmaceutical and medical products. This work reports on the deposition of antimicrobial coatings based on silver nanoparticles (Ag NPs) embedded in an organosilicon film onto woven and nonwoven textiles. The Ag nanoparticles admixed with hexamethyldisiloxane (HMDSO) vapours are intr...
