Evaluation of Graphene as an Antimicrobial Additive in Surface Coatings
The ongoing COVID-19 pandemic has highlighted the importance of material surfaces in virus transmission. As the world recovers, there's a growing need for antimicrobial surfaces that inhibit fungi, bacteria, and viruses. Nano-sized materials like titanium dioxide, silver, copper, and more recently graphene and carbon nanotubes, have demonstrated antimicrobial properties. However, metal additives in coatings often raise environmental sustainability concerns. Graphene, with its sharp edges, high electron mobility, and lubricating nature, shows promise in disrupting cellular membranes, oxidizing microbes, and creating low-friction surfaces. This feasibility study by Talga explores the antimicrobial properties of graphene-containing coatings, aligning with the government's clean growth strategy.
Feedback Overview:
The idea of using graphene as an antimicrobial additive in surface coatings is highly innovative and timely, given the current global focus on hygiene and sustainability. To successfully reach product-market fit, it is crucial to conduct comprehensive testing to ensure the efficacy and safety of graphene-based coatings. Additionally, partnering with regulatory bodies to address any environmental concerns will be vital. Expanding the application range of these coatings beyond the initial target market could also increase business value.
