Organic semiconductor have been discovered in different application devices such as organic light emitting diodes (OLEDs). Poly [2-methoxy-5(2' -ethylhexyloxy)-1, 4-phenylenevinylene), MEH-PPV used in optoelectronic devices because it is easily synthesizing and deposit in high molecular weight and good purity. The evaporating temperature at 750°C with 5 sccm flow of ZnO, the weight of 5 mg/ml and temperature at 50°C were chosen to fabricate MEH-PPV: ZnO nanocomposites on the optimal properties. MEH-PPV: ZnO nanocomposites was prepared by spin coating technique at room temperature. MEH-PPV: ZnO nanocomposites thin film was investigated at pure MEH-PPV (0 wt%) and 0.2 wt% of ZnO. The surface morphology revealed that 0.2 wt% of ZnO showed uniformity and less aggregation compared to MEH-PPV thin film. The electrical properties showed that the ZnO composition at 0.2 wt% exhibits the highest conductivity of 7.40 x 10-1 S. cm-1 compared to polymer thin film this value suitable applied in optoelectronic devices. © 2019 Author(s).
