Switching Behaviors of Ferroelectric and Relaxor Polymer Blend Films
- 15 Downloads
Ferroelectric polymer blend film with non-polar relaxor polymer shows composition dependency of switching behaviors. Studies of ferroelectric properties in polymer blend films with increase volume fraction of relaxor polymer revealed inversely decrease both remnant polarization and coercive voltage, simultaneously. The reduced coercive voltage of the blend with films with higher volume fraction of realxor polymer relative to that of pure ferroelectric film is consistent with the high frequency of applied voltage. Nanoscale ferroelectric polarization switching of blend film was also faster than that of pure ferroelectric film.
