Non-aqueous core-shell dispersion with a cross-linked acrylic core and poly(aniline)/DBSA shell
The electrically conductive microgel coated with PANI-DBSA was prepared in organic media containing polymeric microgel and dodecylbenzenesulfonic acid (DBSA) using ammonium persulfate(APS) as an oxidant. According to the images of the transmission electron microscopes, the prepared conductive microgel has a core-shell microsphere, which is composed of cross-linked acrylic core and PANI-DBSA shell. The particle size of the prepared conductive microgel ranges in 80similar to90 nm. The electrical conductivity can reach values as high as 0.2similar to0.8S/cm. The highly conductive transparent film could be notably obtained by using small amount of nonaqueous conductive microgel.
