Besides the use in textiles, it was discovered that some nylons also exhibit so called "ferroelectric properties." This means that positive and negative electric charges can be separated and this state can be maintained. The ferroelectric materials are used in sensors, actuators, memories and energy harvesting devices. The advantage in using polymers is that they can be liquified using adequate solvents and therefore processed from solution at low cost to form flexible thin-films which are suitable for electronic devices such as capacitors, transistors and diodes. This makes ferroelectric polymers a viable choice for integration with e-textiles. Although nylon polymers have found over the years significant commercial applications in fabrics and fibers, their application in electronic devices was hindered because it was impossible to create high quality thin films of ferroelectric nylons by solution processing.

Scientists at the MPI-P, in collaboration with researchers from the Johannes Gutenberg University of Mainz and Lodz University of Technology, have now solved this forty year old problem, and developed a method to fabricate ferroelectric nylon thin-film capacitors by dissolving nylon in a mixture of trifluoroacetic acid and acetone...
