Abstract

Summary: Novel polymeric particles of spherical shape consisting of an electrically insulating poly(styrene-co-acetoacetoxyethyl methacrylate) (PS/PAAEM) core and a conductive shell of poly(3,4-ethylenedioxythiophene) (PEDOT) were synthesized. Electric measurements showed a strong dependence of the conductivity on weight ratio of PEDOT to PS/PAAEM in the composite. As the PEDOT content varied from 2 to 31.4 wt.-%, resistivity of the resulting material changed exponentially from 12 GΩ cm to 100 Ω cm, depending also on the type of the used oxidation agent. Similar studies were performed on the basis of insulating poly(N-vinylcaprolactam-co-acetoacetoxyethyl methacrylate) (PVCL/PAAEM) microgel particles, which acted as microreactors for the synthesis of conductive PEDOT nanorods. In microgel systems, the conductivity was lower than in core-shell systems, when the PEDOT content was less than 5 wt.-%. Above this value of PEDOT concentration, the conductivities in the two systems became similar.
