General description

3,4-Propylenedioxythiophene (PRODOT) is a conductive polymer that forms a π-conjugated system. It has good electrochromic properties with high conductivity and surface electroactivity. It forms a thin film by using layer by layer (LBL) technique and spin coating.

Application

PRODOT can be used as a conjugated polymer in the fabrication of dye sensitized solar cells (DSSCs), sensors and electrochromic materials.

We vapor print conformal conjugated polymer electrodes directly onto living plants and use these electrodes to probe the health of actively growing specimens using bioimpedance spectroscopy. Vapor-printed polymer electrodes, unlike their adhesive thin-film counterparts, do not delaminate from microtextured living
