The invention belongs to the field of preparation of piezoelectric thin film materials and relates to a direct-writing preparation method of a high-flexibility organic
electrode. The method comprisesthe specific steps that firstly, a piezoelectric thin film 3D model is established and
cut into a slice; then, multi-wall carbon nanotubes are weighed and mixed with an N-methylformamide solution, themixed solution is subjected to
ultrasonic dispersion to be uniform, and a precursor solution is obtained;
polyaniline,
polyvinylidene fluoride and
acetone are added, sealing and ultrasonic dissolvingare conducted until complete
dissolution is achieved, and writing ink is obtained; finally, a writing process and technology are set, a writing program is started, and the organic
electrode is obtained. According to the direct-writing preparation method of the organic
electrode, on the basis of guaranteeing smooth printing, the high-
conductivity and high-flexibility organic electrode can be obtained; through flexible design for a writing trajectory, shapes and patterns which cannot be obtained by a traditional technology are directly written, the writing trajectory program is controllable, the electrode size is more accurate, and the application prospect is wide.
