Abstract. In this study, the effect of addition of single-walled carbon nanotubes (SWCNTs) on the morphological properties of poly(3,4-ethylenedioxythiophene/poly(4-styrenesulfonate) (PEDOT:PSS) has been investigated using scanning electron microscope (SEM) as well as the surface roughness evaluation by atomic force microscopy (AFM). The spin-coated films of PEDOT:PSS and PEDOT:PSS with addition of SWNTs (0.5 % by wt.) on glass were compared in our study. Experimental results show that surface roughness of PEDOT:PSS layers increases after addition SWNTs to the solution -from 3.50 nm for the samples without SWNTs to 4.65 nm for the samples with SWNTs. The analysis of SEM images showed that there are some agglomerations of SWNTs on the surface of PEDOT:PSS/SWCNT composite film.

“…A metallic electrode was deposited over the active layer to finalize the fabrication of the electroluminescent device produced with a lightemitting composite (LECEL -Light-Emitting Composite Electroluminescent Device). The fabrication of LECEL is advantageous because solution-processed materials can be processed by simple printing or coating methodologies, such as screen-printing [27], spray-coating [28], spin-coating [29], drop-casting [8], and roll-to-roll [30].…”

Light-emitting composites are materials that combine the light-emitting characteristic of phosphor materials with the solubility of conductive polymers. This paper has the purpose of showing an experimental study on electroluminescence in a light-emitting composite comprising PEDOT:PSS as the conductive polymer and Zn 2 SiO 4 :Mn as the phosphor material. The relationship between d.c. current and voltage, as well as luminance and voltage, of light-emitting devices were measured for different active layer thickness and different temperature conditions. Luminance was also measured during impedance spectroscopy experiments (a.c. characterization). It was observed that the electroluminescence in the studied light-emitting composite is a field effect mechanism, with turn-on electric field of (4.6 ± 0.2) kV/cm, and that the electroluminescence efficiency is independent of temperature. Additionally, it was observed that electroluminescence is strictly dependent on the drift current of charge carriers. Finally, a model was proposed to describe the electrical properties and luminance of the studied light-emitting composite.

In this work the high frequency properties of low curing temperature cobalt nanoparticle inks printed on polycarbonate substrates were investigated. The inks consisted of 30-70 vol.% metallic cobalt nanoparticles and poly (methylene methacrylate) polymer, having excellent adhesion on polycarbonate and a curing temperature of 110°C. The influence of binder material content on the electromagnetic properties of the ink was investigated using the shorted microstrip transmission-line perturbation method. Changes in mechanical properties were evaluated with adhesion tests using the pull-out strength test and the ASTM D 3359-B cross-hatch tape peel test. The microstructure of the printed patterns was investigated with field emission scanning electron microscopy (FESEM). The inks remained mechanically durable with metal contents up to 60 vol.%, achieving pull-off strength of up to 5.2 MPa and the highest marks in adhesion of the tape peel test. The inks obtained a relative permeability of 1.5-3 in the 45 MHz-10 GHz band with a magnetic loss tangent of 0.01-0.06. The developed inks can be utilized in various printed electronics applications such as antenna miniaturization, antenna substrates and magnetic sensors or sensing.
