  • Stretchable conductive nanocomposite particles
    Patent number: 11810688
    Abstract: Electrically conductive nanocomposite particles including a core of a C1-C6 alkyl polyacrylate homopolymer or a copolymer of C1-C6 alkyl acrylate and of an ?,?-unsaturated amide comonomer, a shell of polyaniline, and a non-ionic surfactant, for printing on a stretchable substrate. Also, a printed stretchable substrate obtained from the electrically conductive nanocomposite particles, which is usable, for example, in the field of printed electronics or connected clothing.
