The car industry also employs two of graphene and carbon nanomaterial’s most important physical properties: tensile strength and lightness. These two properties mean that a huge variety of components with enhanced properties can be fabricated, from exterior panels to chassis components.
Resins containing graphene and other carbon-based nanomaterials can provide scratch and corrosion-resistant finishes (on headlights and bodywork) and prevent static electricity build up thanks to graphene nanomaterial’s conductivity. Reinforced thermoplastic polymers can also be used to fabricate interior components with self-heating capability (Joule effect) or with excellent thermal conductivity that confers thermal dissipation capacity to the thermoplastic to prevent overheating.
Another possible use for graphene and carbon-based nanomaterials excellent thermal conductivity is its use as an additive in brake discs, where it acts as a lubricant, reducing heat build-up caused by friction. It is also used by tyre manufacturers to increase strength and reduce heat build-up.
Finally, the use of graphene in car batteries speeds up charging and increases the storage capacity.
