When adding generation deformation during condition, material recovers again original shape.So, claim it to have " memory " function.
When replying deformation due to shape-memory polymer, it is generally in glass transition or melting transition.This makes its time
Combined stress is usual the lowest (mechanical property of macromolecular material), only zero point several MPas to tens MPas.Therefore, for material exists
There is high recovery stress, it is necessary to use other materials to strengthen during deformation.
CNT is the novel enhanced material being widely used in various field, particularly high-performance composite materials field.
CNT can regard the hollow pipe curled into by single or multiple lift Graphene as.Have stronger intermolecular each other
Interact.When CNT is directly blended with polymeric material, polymeric matrix interaction force between CNT
More weak, material still can not produce high recovery stress；And when content of carbon nanotubes is higher, materials processing difficulty.But, carbon nanometer
When pipe content is higher, CNT can limit the warm-up movement of macromolecular chain, and this restriction effect can make the vitrification of polymer turn
Temperature is to elevated temperature excursions [1]；Meanwhile, when the CNT degree of orientation is higher, the intermolecular interaction of CNT can strengthen.
