Abstract
To obtain the high compressive electrostriction indicated by maximum strain (Smax) at low electric field (Emax), a dependence of solidification thickness on Smax was investigated for carbon nanoparticles dispersed polyurethane (PU) composite films. The thickness dependent Smax at 20MV/m from 7.52% for 143μm thickness to 47.7% for 21μm thickness exhibited linear relationship, which was parallel to that of pure PU. Both thinning and nanoparticles addition enhanced the Smax within the linear relationship. Considering with crystalline volume fraction and crystalline periodicity, the thickness dependent Smax was explained. Effects of nanoparticles addition on Smax were probably contributed by the polarization enhancement induced by increasing the capacitance.
