Abstract—Graphene/epoxy shape memory composites were fabricated with graphene from a simple and low
cost method of chemical oxidation-reduction process. The fine and homogeneous dispersion of graphene
throughout the epoxy matrix with different graphene mass fraction were prepared and their properties were
investigated. It was found that storage elastic modulus rose with the increase of graphene mass fraction, which
indicated that the recovery stress of graphene/epoxy composites would be greater than that of the pure epoxy.
The graphene/epoxy composites with lower content graphene showed a good shape memory effect and a recov-
ering speed superior to the pure epoxy.
