Abstract:
The combined results of the present investigation of Nylon 5 and Nylon 9 and the previous investigation of Nylon 11 and Nylon 7 reveal that the odd-numbered nylons exhibit classic ferroelectric J-E and D-E hysteresis behavior at room temperature. In addition, the remanent polarization, P, of Nylon 5 and Nylon 9 are found to be 125 approx. 130 mCsq meters and 65 approx. 70 mCsq meters, respectively. The remanent polarization of the odd nylon series is observed to increase linearly with increasing dipole density as does the melting point. The coercive field also shows a linear increase with dipole density. The present study also shows that both uniaxially oriented and unoriented odd-numbered nylons exhibit ferroelectric hysteresis behavior, and that the ferroelectric response can be significantly enhanced by uniaxial orientation.
