Abstract

• The wettability behavior of MDMO-PPV solution on NiO and Ag/NiO substrates was investigated by contact angle measurement. The present study focuses on the effect of polymer solution concentration (6-10-14 mg/ml) and solvent (dichlorobenzene) on the wettability of substrate surface. The measured contact angles are 12°, 11° and 10°on NiO films and 22°, 17°, 12° on Ag/NiO films, 14°, 11°, 10° on Ag/NiO films, 19°, 16°, 14° on Ag/NiO films at different silver concentrations (2.5, 5, 10 mM) for polymer concentration of 6, 10 and 14 mg/ml. There is no significant changes in contact angle measurements of MDMO-PPV on NiO and Ag/NiO films.
