Graphene from tires: scientists presented new technologies
A second life to unnecessary tires was presented by scientists from Rice University. Researchers have discovered a way to convert secondary raw materials into graphene, which is then used in the manufacture of concrete. The creators noted that this method of producing graphene is not only environmentally friendly, but also makes concrete more durable and reliable.
The development is based on the previous experience of scientists in the formation of graphene using instant Joule heating technology. This process involves the use of an electric discharge to heat a variety of carbon sources to a temperature of 2725 ° C. As a result of exposure to high temperatures, carbon takes the form of flakes of turbostratic graphene. Its layers do not coincide with each other. Thanks to this, it is able to integrate with various composite materials.
The pyrolysis process is carried out by burning old tires in conditions with a specific low oxygen content. As a result, researchers obtain oil that is used in many areas of industrial production.
A year ago, engineers already researched this technology. The difference was that the experiment used a variety of garbage, such as plastic or food waste. Only after a while the team came up with the idea to use old tires in the experiments.
Given that the first attempts at converting tires to graphene were disastrous, scientists in the next attempts used the material that resulted from the planned stages of processing. Scientists note that concrete created from the resulting substance under compression shows a level of strength 30% higher than standard indicators.
