Scientists at 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 and solidifying it again in a vacuum.
Chemical analysis carried out by electron microprobe (Jeol JXA 8200 at the Institute for Geosciences,
Johannes Gutenberg University of Mainz, Germany) yielded 73.47 wt.% Si[O.sub.2], 3.72 wt.% [Al.sub.2] [O.sub.3], 6.68 wt.% [Na.sub.2]O, 8.59 wt.% [K.sub.2]O, 3.40 wt.% FeO and 0.64 wt.% MnO.
