An effective approach to fabricate micropatterned reduced graphene oxide sheets is explored on the basis of the pressure‐assisted thermal graphitization as a concept of eco‐friendly method. The high pressure can considerably reduce the graphitization temperature and substantially accelerate the kinetics of phase transformation of non‐crystalline graphene domain, leading to enhance the degree of graphitization.
