Abstract :
This paper presents results of different dilutions of PEDOT:PSS on the uniformity, pattern definition and conductivity of inkjet printed films. PEDOT:PSS was diluted in water, ethylene glycol (EG) and dimethyl sulfoxide, (DMSO) in order to achieve the required viscosity in the range of 2 to 30 cps. In order improve the surface tension a surfactant Tritonreg X100 was added to some of these dilutions. Deposited films were characterized to obtain their refractive index, thickness and resistivity. As a final result, a polymeric light emitting diode (PLED) structure was fabricated using copolymer (BEHP-PPV)-co-(MEH-PPV) as active layer.
