Abstract : Nylon 11 (gamma phase) is electrically poled after it is crystallized from commercially available nylon 11 by rapidly crystallizing it from the molten state. The gamma-phase nylon 11 so obtained exhibits high piezoelectric properties when poled under different poling conditions at different temperatures. The electrically poled gamma-phase nylon 11 is used in a transducer.
