NoteThis paper describes a novel spray emulsion polymerization technique for the preparation of aqueous-dispersible nanoscale core/shell poly(3,4-ethylenedioxythiophene) (n-PEDOT) colloids doped with poly[(4-styrenesulfonic acid)-co-(maleic acid)] (PSS-co-MA). Scanning electron microscopy and transmission electron microscopy images revealed that these n-PEDOT:PSS-co-MA colloids possessed sharp core/shell morphologies. X-ray diffraction and Raman spectroscopy measurements revealed semi-crystalline morphologies and quinoiddominated structures for these n-PEDOT:PSS-co-MA colloids. The conductivities of n-PEDOT and n-PEDOT:PSS-co-MA pellets were ca. 3.2 and 0.29 S cm1, respectively, suggesting that PSS-co-MA acted as a shell that blocked the hopping of charges from the n-PEDOT core to neighboring latexes. The work functions of pristine n-PEDOT and n-PEDOT:PSS-co-MA, measured using photoelectron spectroscopy, were ca. 4.7 and 5.05 eV, respectively; thus, they are close to that of indium
tin oxide. The PSS-co-MA used in this study featured two different types of interactive functional groups, which acted as oxidative sites, dopants, and core/shell
