We suggest a novel method of fabricating water-borne colloids of semiconducting polymers for use in environmentally benign processes involving organic electronics, without compromising the high charge carrier mobility of the polymeric semiconductors. Non-ionic surfactants were utilized as a key material to fabricate aqueous colloids of semiconducting polymers via a miniemulsion process. By developing smart surfactant engineering techniques, we could selectively remove non-ionic surfactants after film deposition, rendering efficient inter-particle charge coupling. We introduced such non-ionic surfactants-technique onto a donor-acceptor type polymeric semiconductor with an inherently high charge carrier mobility, resulting in a high-mobility (~2.51 cm2V-1s-1) water-borne polymer field effect transistor for the first time. |
