Embodiment 1

[0032] Embodiment 1 Preparation of high conductivity shape memory material

[0033] Composition in parts by weight of raw materials: 100 parts of shape memory material; 5 parts of multi-walled carbon nanotubes; 3 parts of dispersant;

[0034] The shape memory material was prepared by the following method: 8 g of freshly distilled ε-caprolactone (ε-CL) and 2 g of freshly purified 1,4,8-trioxopyrimidine-[4,6]-9- Undecanone (TOSUO) was added to a 250mL strictly dry nitrogen round-bottomed flask connected to a vacuum adapter, and then 1mg of stannous octoate was added with anhydrous toluene as a solvent. After mixing well, azeotrope under reduced pressure (<20Pa) at 60°C for 2 hours; finally, immerse the flask in a preheated oil bath at 115°C, and react under vacuum for 24 hours. The obtained product was cooled and purified by sedimentation with dichloromethane / ethanol system, then centrifuged and dried in a vacuum oven at 35°C to obtain the shape memory material.
