This presentation covers the fabrication; characterization and potential application of electro activate shape memory polymer (SMP) containing multi-walled carbon nanotubes (MWCNTs), hybrid fillers of carbon black (CB) and short carbon fiber (SCF), and magnetic Ni power. The electrical conductivity of 8 wt% MWNTs composite is 1.25 x 10–2 S/cm with dimension of 8.0 cm x 2.0 cm x 0.2 cm rectangle sheet, it can be triggered by passing an electrical current with a constant voltage of 200 V. While, the electrical conductivity of the composite, containing 5 wt% CB and 2 wt% SCF, reaches to 3 S/cm. Their shape recovery can be induced by passing an electrical current of 25 V voltages. SMP filled with 10 vol% Ni, induced by 20 V. Then temperature-dependent resistivity test is done to investigate the thermo-sensitive effects in conducting polymer composite, and it shows a classical negative temperature coefficient (NTC) effect ranged from 70°C to 90°C. Thus smart thermal sensor using conducting SMP composite can be realized through resistivity change.
