Microstructure and electromechanical properties of carbon nanotube/poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) composites
The ferroelectric relaxor terpolymer (P(VDF-TrFE-CFE) has a dielectric constant above 50 at room temperature and giant longitudinal strain. By adding only 0.5 wt.-% functionalized multiwalled carbon nanotubes, its crystallinity (light blue, see Figure), Young's modulus (green), dielectric constant (dark blue), and electromechanical response (maroon) can be simultaneously improved (see Figure).
