Abstract: The invention provides a polymer material with two-way shape memory. The polymer material comprises two interpenetrating network polymers which are arranged in an interpenetrating manner; and one network polymer is a shape memory polymer of crystallized crosslinked polymer, and the other network polymer is a crosslinked elastic material. According to the polymer material with two-way shape memory and based on the performance and structure principle of the interpenetrating network polymers, the two interpenetrating network polymers are arranged in an interpenetrating manner to form a memory polymer material, one is used as a shape memory contraction part which can be contacted due to heating; the other polymer network is used as an energy storage part; when the first network polymer is contacted due to heating and the second network polymer is compressed, the compressed second network polymer provides a restoring force for the first network polymer after heating is cancelled, so as to be used for restoring the shape before heating, so that the polymer material of the interpenetrating network manner has a two-way shape memory effect.
