Why do you want me to explain it when you could check Wikipedia?

Each carbon atom has 1 free electron allowing conductivity. If a hydrogen atom is added to each carbon, it is then called 'graphane' which is an insulator. Thus hydrogen could be used to draw circuits on graphene.

Why is it so strong?

coz it is essentially a huge aromatic system/network, i think.
