Graphene and derivatives – Synthesis techniques, properties and their energy applications (2017, neutral): “Peng et al. [123] have reported the fracture toughness of pristine graphene as 4 Mpa √𝑚 , it can be noted from the values that the graphene tends to form agglomerates and imperfections in graphene leads to the brittle nature.”
