Abstract :
An unusual ferroelectric behavior of nylon 11 has been observed at high temperature. The very large value of the remnant polarization shows that the dipole in the amorphous regions of the semi-crystalline odd nylons could have an important contribution to the ferroelectric polarization. The homocharge and heterocharge are related with the applied electric field. The spectra of thermally stimulated depolarization current at the different poling conditions are reported and discussed
