The 'wonder material' graphene can be made using a kitchen blender, a mobile phone and a newspaper
There is something slightly ridiculous about using a kitchen blender to make graphene. This is, after all, the "wonder material" associated with futuristic technologies. You might reasonably expect its production to involve equally futuristic equipment. Often, it does.
Graphene, hailed as the "wonder material" for futuristic technologies, traditionally requires advanced equipment for production. However, a recent study suggests that this remarkable substance can be synthesized using everyday items like a kitchen blender, mobile phone, and newspaper. The research, published in ACS Sustainable Resource Management, investigated the possibility of producing graphene using graphite from electronic waste, old newspaper, and tap water.
Graphene, known for its exceptional strength and conductivity, has found applications in power banks, batteries, medical sensors, and stronger concrete. However, its production often involves complex and expensive processes. The study aimed to determine if graphene could be made using more accessible materials found in households.
The researchers employed a liquid-phase exfoliation process, which involves breaking down the stacked layers of graphite into individual sheets of graphene. To facilitate this separation, they used a kitchen blender to mix graphite, newspaper, and tap water. The newspaper, rich in cellulose, acted as a temporary barrier, preventing the graphene sheets from recombining.
The solution remained viable for several hours, and the graphene could be recovered by shaking the mixture. While the resulting liquid from the blender did not conclusively prove the presence of graphene, sophisticated laboratory equipment confirmed the successful production of graphene. Remarkably, the process required minimal specialized equipment, highlighting the potential for graphene production to occur in lower-budget settings.
The findings suggest that graphene production could be democratized, allowing schools, community laboratories, and even citizen-science projects to participate. By using materials readily available in most homes, such as newspaper, tap water, and graphite, the study demonstrates that advanced equipment primarily serves to verify the results rather than being a prerequisite for the experiment.
This approach could significantly reduce the barriers to entry for graphene research, particularly in regions with limited resources.
