- •
The size effect of the mechanical properties of graphene/PET interface is studied.
- •
Seven graphene specimens with varied lengths are tested by Raman experiments.
- •
A scaling factor is defined to evaluate the size-dependent edge effect of grapheme.
- •
The interfacial shear stress and critical length are influenced by size effect.
- •
The failure strength and stiffness of the interface are size-independent.
