“…While the exact mechanism for these surfaces is not yet known, they show promise as they can be generated on a polymeric surfaces and compliment other methods of antimicrobial activity 63 . Surface patterning of polymer was recently found by Sanjay et al to improve the antimicrobial activity of composite surfaces by facilitating the exposure of copper particles to the surface, showing an interesting synergic effect of the addition of surface structure and biocidal fillers 65 . Another example of a combined approach utilizes lotus leaf inspired composites consisting of PDMS with a surface layer of silica nanoparticles functionalized with 3-(trimethoxysilyl)-propyldimethyloctadecyl ammonium chloride reported by Rauner et al 66 .…”

The concept of a circular economy proposes that industrial waste be used as raw material for making new products to reduce the environmental impact and stimulate economic growth. Thus, many scientific studies and patents have aimed to take advantage of different waste compounds in the development of new composite materials. The goal of this study is to assess the potential for using marble and synthetic fibers for the development of new materials through the analysis of patent documents filed worldwide. We analyzed prospective documents in the Derwent Innovation Index database. A total of 129 documents related to the research area of interest was identified between 1958 and 2019. The construction sector had a higher total number of patents and active patents relative to the industrial sector with a focus on structural, antimicrobial, and covering applications. Japan, the United States, and South Korea were the countries that filed the most patents related to the research topic.

“…Once more, an additional copper-containing alternative may be noted herein concerns the work of Muralidharan, which was recounted upon in a master’s thesis from the University of Waterloo. Specifically, a sulphonated poly(ether-ether-ketone)-copper film for antipathogenic functionality was described by Muralidharan et al in 2020 [ 37 ]. Just as Kocaman et al is deserved of continued consideration, Muralidharan’s advancements deserve the same.…”

On the emergence of antibacterial and antiviral copper cold spray coatings

In this literature review, the antipathogenic properties and contact-mediated antibacterial and antiviral performance of copper cold spray surfaces are assessed and compared with alternative antimicrobial materials that are able to kill and/or inactivate infectious agents via direct contact. Discussion is also provided concerning the suitability of copper cold spray material consolidations as biocidal and viricidal surfaces that retain long-term functionality as a preventative measure against fomite transmission of pathogenic agents and hospital-acquired infections from contaminated high-touch surfaces. Numerable alternative antimicrobial coatings and surfaces that do not rely upon the oligodynamic action of copper are detailed. Given the ongoing need for recognition of said alternative antimicrobial materials by authoritative agencies, such as the U.S. Environmental Protection Agency, the relevant literature on non-copper-based antipathogenic coatings and surfaces are then described. Furthermore, a wide-ranging take on antipathogenic copper cold spray coatings are provided and consideration is given to the distinctive grain-boundary mediated copper ion diffusion pathways found in optimizable, highly deformed, copper cold spray material consolidations that enable pathogen inactivation on surfaces from direct contact. To conclude this literature review, analysis of how copper cold spray coatings can be employed as a preventative measure against COVID-19 was also presented in light of on-going debates surrounding SARS-CoV-2’s non-primary, but non-negligible, secondary transmission pathway, and also presented in conjunction with the inevitability that future pathogens, which will be responsible for forthcoming global pandemics, may spread even more readily via fomite pathways too.
