Reversible shape-memory polymers (RSMPs) show great potential in actuating applications because of its repeatability among many other advantages. Indeed, cases, multiresponsive RSMPs are more expected, and the strategy to introduce functional fillers without deteriorating reversible deformation performance is importance. Here, a facile balance electro, photothermal performance, molecular chain mobility reported. Segregated conductive networks carbon nanotubes (S-CNTs) constructed poly(ethylene-co-octene) (POE) matrix at relatively low filler loading, which renders composite good electrical, photothermal, properties. A percolation threshold 0.25 vol % achieved. The electrical conductivity up 0.046 S·cm-1 for POE/S-CNT composites with 2 CNT, absorption light (760 nm) above 90%. These characteristics guarantee that actuator can be driven voltage (≤36 V) suitable intensity (250 mW·cm-2) performance. An electric gripper light-active crawling robot demonstrate robots.
