Ferroelectric performance of nylons 6-12, 10-12, 11-12, and 12-12.

Nylons have great potential for electrical applications requiring high polarizability and low dielectric loss. Recently, the narrow single hysteresis loop with relaxor ferroelectricity and the double hysteresis loop due to antiferroelectricity have been reported in nylon random copolymers, terpolymers, and common even-numbered nylons. Although several studies of ferroelectric nylons have been reported, even-even-numbered and odd-even-numbered nylons have not been sufficiently explored.
