Shape　memory　polymer　(SMP)　has　been　applied　in　many　fields　as　intelligent　sensors　and　actuators.　In　order　to　improve　the　mechanical　properties　and　recovery　force　of　SMP,　the　addition　of　minor　amounts　of　carbon　nanotubes　(CNT)　into　SMP　has　attracted　wide　attention.　A　micromechanical　model　and　thermo-mechanical　properties　of　CNT/SMP　composites　were　studied　in　this　paper.　The　thermo-mechanical　constitutive　relation　of　intellectual　composites　with　isotropic　and　transversely　isotropic　CNT　was　obtained.　Moreover,　the　shape　memory　effect　of　CNT/SMP　composites　and　the　effect　of　temperature　and　the　volume　fraction　of　CNT　were　discussed.　The　work　shows　that　CNT/SMP　composites　exhibit　excellent　macroscopic　thermo-mechanical　properties　and　shape　memory　effect,　while　both　of　them　can　be　affected　remarkably　by　temperature　and　the　microstructure　parameters.
