Shape　memory　polymers　(SMPs)　possess　unique　shape-changing　functionality　that　offer　wide　potential　applications.　However,　SMPs　with　high　mechanical　strength　are　increasingly　needed.　For　this　purpose,　graphene　flakes　can　be　used　for　strengthening　the　pure　SMP　materials.　In　this　paper,　full-atomistic　molecular　dynamics　(MD)　are　used　to　study　the　shape-memory　behaviour　of　a　representative　amorphous　polymer.　The　glass　transition　temperature　of　graphene　reinforced　SMP　(G-SMP)　are　investigated.　The　mechanical　properties　under　uniaxial　tension　at　different　phases　were　obtained.　The　results　show　that　the　glass　transition　temperature　of　the　G-SMP　is　higher　than　that　of　the　non-reinforced　SMP　material.　©　2017　International　Committee　on　Composite　Materials.　All　rights　reserved.
