Episode #6: Graphene in construction
from Institute of Construction Materials | ICONSMAT Hosted by Farid Sartipi
Today's episode is about graphene and its use, particularly, in the construction industry. These nanoparticles of carbon are made in laboratories with two distinctive quality grades. The grade that is made through the so-called chemical vapor deposition yields the highest quality for applications in the electronic industry often and the process is pretty expensive especially when you consider the production rate and the energy consumption. Noteworthy, when we are talking about the quality of graphene, we are actually referring to the size of platelets and the number of carbon layers. Higher quality essentially means larger platelets and thinner layers. Whereas, the other cheaper method which yields a lower quality of graphene is called electrochemical exfoliation where graphite sticks or chunks, depending on your supply are gone under acid attack with a specified concentration and input voltage. As we are dealing with huge volumes of concrete in the construction industry, and cost-effectiveness is always key to successful project delivery, this method of graphene production is being considered as the more suitable way.
