Abstract

Cold‐drawn Nylon‐11 films, which were prepared by stretching the melt‐quenched films to a draw ratio of 2.8: 1 at room temperature, were found to exhibit an electric displacement versus electric field hysteresis loop. The results confirmed that the Nylon‐11 film exhibited ferroelectric behavior at or below room temperature. The coercive fields were 65, 98, 125, 160, and 215 MV/m at 20, 0, βˆ’20, βˆ’40, and βˆ’60Β°C and the remanent polarization at βˆ’20Β°C (where there was considerably less dc conduction) was 56 mC/m^2^. Switching of the polarization was almost completed within 20 ms.

## Abstract We have discovered recently that melt‐quenched and cold‐drawn Nylon ‐ 11 films exhibit very clear ferroelectric hysteresis behavior. In the present study, a remanent polarization as high as 86 mC/m^2^ has been found in Nylon ‐ 7 samples; this is significantly higher than that usually ob

Both poly(vinylidene fluoride) (PVF 2 ) and nylon 11 are ferroelectric polymers, and have been extensively studied over the past two decades. Blend films were made from mixed powders of these two polymers, which were then melt pressed and cold drawn. The ferroelectric properties of these blend films
