An electrothermal composite material includes a flexible polymer layer and a carbon nanotube paper stacked on the flexible polymer layer. The carbon nanotube paper is at least partly embedded into the flexible polymer layer. A thickness ratio of the carbon nanotube paper and the flexible polymer layer is in a range from about 1:7 to about 1:10. A density of the carbon nanotube paper is greater than or equal to 0.5 g/cm3. A thermal expansion coefficient of the carbon nanotube paper is greater than or equal to ten times that of the flexible polymer layer. A conductivity of the carbon nanotube paper along a first direction is in a range from about 1000 S/m to about 6000 S/m. An electrothermal actuator is also provided. |
