1. An information handling system comprising:
a housing;
a processor disposed in the housing and operable to execute instructions that process information;
a memory disposed in the housing and interfaced with the processor, the memory operable to store the instructions and information;
a peripheral device external the housing and interfaced with the processor, the peripheral device operable to perform a peripheral function; and
a printed circuit board disposed in the peripheral device and supporting one or more electronic components, the printed circuit board having at least one prepreg substrate and at least one bio-based substrate and having a layer of graphene disposed between the prepreg substrate and bio-based substrate.
