Light weight vehicle design is a principal keystone to improving fuel efficiency and vehicle performance whilst reducing adverse environmental impacts. At this point, graphene is a solution with a high potential to further reduce vehicle weight and improve mechanical and thermal properties. With a unique combination of mechanical and electrical properties, graphene shows great potential for exploitation in the automotive industry. While graphene is, in the long-term, expected to offer a wide number of solutions, high cost and harsh and acidic production conditions are the challenges in the commercialization. In the present work, we developed a technology to produce graphene nanoplatelets (GNP) from recycled carbon black obtained from the pyrolysis of waste tire by using recycling and upcycling technology. This graphene is comparably cheaper than available ones and thus can be used as a reinforcing agent in thermoplastic polymers. Due to its resulting self-functionalized surface structure, GNP can be easily and directly dispersed in the host matrix without the use of a compatibilizer or surfactant for process stability, and thus there is no alteration required in its surface chemistry. With this developed technology, a pilot production line with the capacity of 500 kg/month in Nanografen Co (spin-off of Sabancı University) was established to initiate the industrialization of graphene in automotive sector. Nanografen is developing cost-effective and light-weight automotive plastic composite parts with co-operation of Renault. Nanografen is official supplier of Renault together with Ravago and they developed OEM certified masterbatch to reduce glass fiber and mineral amount in polypropylene based interior and exterior parts. Consequently, this multidisciplinary work ensures significant innovation potential of graphene in the field of thermoplastic based composites.
