Surfactant-free preparation of water dispersible conjugated polymer nanoparticles and their electroluminescence |
| 초록 |
Conjugated polymer nanoparticles (CPNs) have attracted considerable interest due to their unique optical properties and potential applications in bio-sensors and optoelectronic devices such as light-emitting diodes and solar cells. In particular, water-dispersible CPNs have received special attention as a printable optical ink for cost-effective fabrication of optoelectronic devices. Here, we present a simple approach for fabrication of water-dispersible CPNs with 2-dimensional nanographite oxide sheets (NGO) shell via miniemulsion methods. We found that NGO can act like a surfactant in emulsification process of CPNs due to amphiphilicity with hydrophilic edges and hydrophobic basal plane. 50 ~ 100 nm sized CPNs wrapped by NGO were successfully obtained and their optical properties and electroluminescence characteristics have been systematically investigated. |
