Zusammenfassung:	The invention discloses a preparation method and application of polypyrrole nanocomposite ink for direct writing type 3D printing, and is characterized in that methyl orange, pyrrole and ferric chloride are respectively dissolved and then mixed to obtain polypyrrole nanotubes, then polypyrrole nanotube powder and polydimethylsiloxane are mixed, a curing agent is added, and the polypyrrole nanocomposite ink is prepared. Finally, the prefabricated composite material ink is filtered, bubbles are removed, and the polypyrrole nano composite material ink is obtained. The preparation method has the advantages that the prepared polypyrrole nanocomposite ink has extremely high conductivity and excellent stretchability, the preparation method is simple, the preparation cost is low, and mass production can be achieved. A flexible strain sensor obtained through 3D printing by using the polypyrrole nanocomposite ink prepared by the preparation method disclosed by the invention is relatively stable in output resistance pea
