“…Anodized aluminum layers have shown good compatibility with different types of silver-based fillers, confirming excellent antibacterial performance [47][48][49]. Furthermore, antimicrobial silver has been encapsulated in TiO 2 coatings [50] and TiO 2 nanotubes [51], deposited on cotton fabric [52], and implemented in a Mg-Al layered double hydroxide coating [53].…”

In this work, colloidal silver has been added into an acrylic clear cataphoretic bath, evaluating the effect of two different filler amounts on the durability of the composite coatings. The three series of samples were characterized by electron microscopy to assess the possible change in morphology introduced by the silver-based additive. The protective properties of the coatings were evaluated by a salt spray chamber exposure and electrochemical impedance spectroscopy measurements, evidencing the negative effect provided by high amount of silver, which introduced discontinuities in the acrylic matrix. Finally, the durability of composite coatings was studied by exposing them to UV-B radiation, observing a strong phenomenon of silver degradation. Although the coating containing high concentrations of silver demonstrated poor durability, this study revealed that small amounts of silver can be used to provide particular aesthetic features, but also to improve the protective performance of cataphoretic coatings.

“…Although silver nanoparticles (Ag NPs) themselves own different functional features, such as electrical conductivity, photocatalytic and antibacterial activity, their aggregation tendency and low stability on textiles lead to the reduction of Ag NPs efficiency [ 100 ]. Therefore, Ouadil et al [ 100 ] and Makowski et al [ 118 ] combined graphene with Ag NPs for coating of polyester and cotton fabric, respectively, and, thus, increasing the dispersion, stability and activity of Ag NPs. Moreover, graphene particles exhibit antibacterial activity, depending on their dispersibility, adsorption ability, number of corners and sharp edges [ 118 ].…”

Moreover, graphene particles exhibit antibacterial activity, depending on their dispersibility, adsorption ability, number of corners and sharp edges [ 118 ]. Herein, three mechanisms are involved, namely, the action of the sharp edges, oxidative stress, and wrapping or trapping of bacteria due to the flexible thin-film structure of graphene, disrupting the cellular membranes and causing their integrity loss.…”

A Review of Electro Conductive Textiles Utilizing the Dip-Coating Technique: Their Functionality, Durability and Sustainability

The presented review summarizes recent studies in the field of electro conductive textiles as an essential part of lightweight and flexible textile-based electronics (so called e-textiles), with the main focus on a relatively simple and low-cost dip-coating technique that can easily be integrated into an existing textile finishing plant. Herein, numerous electro conductive compounds are discussed, including intrinsically conductive polymers, carbon-based materials, metal, and metal-based nanomaterials, as well as their combinations, with their advantages and drawbacks in contributing to the sectors of healthcare, military, security, fitness, entertainment, environmental, and fashion, for applications such as energy harvesting, energy storage, real-time health and human motion monitoring, personal thermal management, Electromagnetic Interference (EMI) shielding, wireless communication, light emitting, tracking, etc. The greatest challenge is related to the wash and wear durability of the conductive compounds and their unreduced performance during the textiles’ lifetimes, which includes the action of water, high temperature, detergents, mechanical forces, repeated bending, rubbing, sweat, etc. Besides electrical conductivity, the applied compounds also influence the physical-mechanical, optical, morphological, and comfort properties of textiles, depending on the type and concentration of the compound, the number of applied layers, the process parameters, as well as additional protective coatings. Finally, the sustainability and end-of-life of e-textiles are critically discussed in terms of the circular economy and eco-design, since these aspects are mainly neglected, although e-textile’ waste could become a huge problem in the future when their mass production starts.

“…In recent research, Makowski et al fabricated electroconductive antibacterial fabrics through thermal reduction of GO to rGO followed by electrochemical deposition of Ag particles on the fabric. [22] Therefore, the technique still requires elevated temperature for the reduction of GO. Hence, an alternative simpler method that could solve the contamination and heating problems constitutes an important need.…”

Facile Electrochemical Preparation of Hydrophobic Antibacterial Fabrics Using Reduced Graphene Oxide/Silver Nanoparticles

A novel facile electrochemical method was developed for in situ coating of fabrics with reduced graphene oxide/silver nanoparticles. The procedure consisted of three steps: spray coating of graphene oxide on the fabric, electrochemical reduction of the graphene oxide layer, and electrodeposition of silver nanoparticles on the fabrics. All the steps were performed at room temperature without using a toxic reducing agent. The fabrics coated with reduced graphene oxide/silver nanoparticles demonstrated excellent hydrophobicity (water contact angle of 148.0°±1.1) and strong antibacterial activity against gram‐negative Escherichia coli bacteria (reduction rate >99.99 %). The durability of the modified fabrics was investigated by a washing experiment. Based on the results of this test, the reduction rate of the fabric did not decrease after 60 washing times. The results of the silver ion release test revealed a slow leaching rate from the fabric which confirms the long‐term antibacterial activity of the fabrics.
