“…This direct absorption method was used to incorporate fatty acid PCM materials into a polymeric substrate in another study . In next step, the addition of Keliab solution as a green alkali formed hydroxyl ions; these could hydrolyze both the polyester fibers and the fatty acids . On this basis, carboxylate (─COO − ) and hydroxyl (─OH) functional groups and sodium and potassium salt of the fatty acids were generated on polyester chains [Equations –] .…”

This article introduces a facile approach for applying a eutectic mixture of fatty acid phase-change materials (PCMs) on polyester fibers for thermal conductivity improvement via the in situ incorporation of copper nanoparticles. For this purpose, a eutectic mixture of palmitic acid and lauric acid was applied as PCMs and ascorbic acid was applied for the synthesis of copper nanoparticles. The thermal properties and stability of the treated samples were also determined by differential scanning calorimetry and thermogravimetry analysis. The treated samples indicated appropriate phase-transition temperatures between 29.1 and 36.8 C, with relevant latent heats of 49.4 and 49.9 J/g, respectively. The in situ formation of copper nanoparticles into eutectic fatty acid applied on the polyester fibers resulted in the promotion of the thermal conductivity of the composite by about 100.1% with the maximum amount of nanoparticles. In addition, the treated samples maintained good thermal durability and stability after 100 melting and freezing cycles. In addition, the tensile strength of the treated samples was improved. Overall, this treatment could be used to produce promising form-stabilized composite PCMs and thermoregulated polymers and textiles with appropriate phase-transition ranges and thermal conductivity.

“…Nabil et al [ 49 ] also treated cotton fibers with an aqueous solution composed of hydrogen peroxide and ammonium hydroxide to hydroxylate the cotton, that is, to introduce hydroxyl groups that would bind or be replaced with other chemical products that would be added after the functionalization with CuO. In the case of the group led by Rezaie, they previously washed a wool sample with a nonionic detergent solution to remove impurities [ 50 ]. Subsequently, to synthesize CuO NPs in the presence of textile materials, the authors immersed and stirred the samples with previous treatments in solutions of copper precursor salts, such as copper sulfate or acetate, and then treated them with alkaline solutions from an industrial source (sodium hydroxide or sodium borohydride) or solutions obtained from natural sources, as they did in Rezaie’s research, who used the supernatant produced after dissolving the ashes of burnt leaves and the stems of the Seidlitzia rosmarinus plant in water.…”

Antibacterial Cotton Fabric Functionalized with Copper Oxide Nanoparticles

et al. 2020

Textiles functionalized with cupric oxide (CuO) nanoparticles have become a promising option to prevent the spread of diseases due to their antimicrobial properties, which strongly depend on the structure and morphology of the nanoparticles and the method used for the functionalization process. This article presents a review of work focused on textiles functionalized with CuO nanoparticles, which were classified into two groups, namely, in situ and ex situ. Moreover, the analyzed bacterial strains, the resistance of the antimicrobial properties of textiles to washing processes, and their cytotoxicity were identified. Finally, the possible antimicrobial mechanisms that could develop in Gram-positive and Gram-negative bacteria were described.

“…Many antimicrobial textiles are metal impregnated, often with copper or silver engineered nanoparticles (ENPs) [17][18][19][20][21][22][23][24] . In one of the rst studies to demonstrate the potential leaching behavior of commercially available ENP-impregnated textiles, Benn and Westerhoff observed up to 650 µg of silver leached into 500 mL of distilled water from a single commercial sock 25 .…”

Metal Leaching from Antimicrobial Cloth Face Masks Intended to Slow the Spread of COVID-19

Global health organizations recommend the use of cloth face coverings to slow the spread of COVID-19. Seemingly overnight, companies whose primary business is in no way related to healthcare or personal protective equipment – from mattresses manufacturers to big box stores – transitioned into the “mask business.” One of many options on the market are antimicrobial face masks, some of which contain silver and/or copper that may leach out of these masks. We exposed ten face masks to deionized water, laundry detergent, and artificial saliva to quantify the leachable silver and copper as a result of mask washing and wearing. Leaching varied widely across brand, metal, and leaching solution, but in some cases was as high as 100% of the metals contained in the as-received mask after 1 hour of exposure. This could lead to a total adult body metal exposure of up to 900 µg/kg of silver and 75 µg/kg of copper by wearing a given mask over an 8-hour workday. While this exposure could be minimized by pre-washing the cloth masks, this would seem to eliminate any (perceived) antimicrobial properties as the metals are eliminated into wastewater and/or graywater.
