Influence of Metal Ions Functionalized CNT Based Polyurethane Electroactive Shape Memory Actuators |
| 초록 |
Polyurethane based nano particle decorated multi wall CNTs composite with were prepared by the melt mixer process, which was followed by hot compression molding. The morphology of metal particles functionalized carbon nanotube filler in polyurethane matrix and resulting conductivity of the composites were investigated. Their thermal and mechanical properties and electro active shape memory behavior were studied by wide angle X-ray diffraction (WAXD), XPS, tensile and dynamic mechanical analysis (DMA). The Tgs of these composites were in range of 33 – 53oC and influenced by addition Metal functionalized CNT ratio of PU soft and hard segment. These composite can restore their shapes almost completely attain 100% original position with addition of less amount of CNT filler in PU matrix at applied 50V in 10 sec. Therefore these PU/ M-CNT composites are expected to find out smart actuator application. |
