The composite films of cesium nitrate (CsNO

) and poly(vinyl alcohol) (PVA) with varying composition were prepared using the solvent cast method. The hysteresis loop characteristics show optimum remnant polarization (

) of 2.75 μC/cm

at 50 wt.% composition. The field emission scanning electron microscope images show a nearly homogeneous distribution of CsNO
3
grains in the 50 wt.% composite film. The temperature dependence of the remnant polarization shows a diffused transition temperature range from the ferroelectric to the paraelectric phase and this has been attributed to the reduced enthalpy. The butterfly features of the dielectric constant–voltage (

) characteristics have been attributed to polarization switching.
