How does Graphene work to block unwanted radiation?

Graphene radiation blocking properties are due to its unique optical properties. In layman’s terms, the microchip made from graphene works similar to a pair of polarized sunglasses. As in, the chip allows only radiation of a particular frequency to pass through it and effectively blocks all other radiation frequencies. The uniqueness of graphene thus makes it transparent and opaque to radiation simultaneously.
In this simple way, it can store and control transmission of the required frequencies (data) and ensures faster and better quality wireless data transmission. Nano-based materials are considered to be the future of the technological revolution. It makes a highly potential material for not only anti-radiation properties but also for thermal shields in space shuttles too.
