30 March 2010 Non-linear actuation response of polyvinylidene fluoride (PVDF) based nanocomposites
Author Affiliations +
Recent research on overcoming inherent limitations on the electromechanical properties of polyvinylidene fluoride (PVDF) and copolymers has been directed towards adding nanoinclusions to take advantage of their scale and properties. This research shows that adding single walled carbon nanotubes (SWNTs) creates a quadratic electromechanical response in PVDF. Enhanced effective dielectric constant and formation of polar microstructure suggests an electrostrictive response. Contributions from Joule heating will be assessed next, as they may be significant at higher SWNT content.
