Abstract
An actuator includes a twisted and coiled polymer fishing line and an untwisted resistance heating wire (TCP) actuator and a coating on the TCPactuator. The coating includes a mixture of carbon nanotubes, metal nanoparticles, and mesoporous carbon nanoparticles, and in some variations, the coating includes a polymer matrix with the carbon nanotubes, metal nanoparticles, and mesoporous carbon nanoparticles disposed in the polymer matrix. And the actuator exhibits enhanced actuator parameters such as actuator efficiency, hydrophobicity, power consumption, actuation frequency, dynamic actuation and cooling rate.
