The correlation between the synthesis modes, chemical composition, crystal structure, surface microstructure, and also the mechanical properties of thin nanostructured Ni – Fe films has been studied. Thin Ni–Fe films on the Si with Au sublayer were obtained using electrolyte deposition with different current modes: direct current and three pulsed modes with pulse duration of 1 s, 10–3 and 10–5 s. It is shown that a decrease in the pulse duration to 10–5 s leads to an increase in the film elastic modulus and the hardness due to the small grain size and a large number of grain boundaries with increased resistance to plastic deformation. The effect of heat treatment at 100, 200, 300, and 400 °C on the surface microstructure and micromechanical properties of the films was investigated. An increase in grain size from 6 to 200 nm was found after heat treatment at 400 °C which, in combination with interfusion processes of the half-layer material, led to a significant decrease in hardness and elastic modulus. Ni–Fe films with improved mechanical properties can be used as coatings for microelectronic body for their electromagnetic protection.

Organic electronics requires the development of reproducible and highly conductive thin films. The arrangement of poly(3,4-ethylenedioxythiophene) (PEDOT) with fullerene C60 leads to products with the combined properties of both species that are excellent candidates for these applications. However, very little has been studied about the effect of doping PEDOT with C60, and thus there is a lack of information regarding the morphology, electrochemical and electrochromic properties of the resulting films. Herein, simultaneous electrodeposition of poly(3,4-ethylenedioxythiophene) (PEDOT) doped with fullerene C60 was carried out via cyclic voltammetry in the range from 0.0 V to +1.5 V (vs Ag/AgCl) in a three-compartment cell. ITO coated on PET was used as both working and counter electrodes. The fullerene presence within the films was confirmed with MALDI and TGA (27.5% of fullerene content). The cyclic voltamograms showed that the C60-doped film has a higher oxidation potential, what was attributed to the electron affinity of the fullerene cage. Furthermore, the spectroelectrochemical and electrochromic analyses showed that the PEDOT/C60 films present a dark violet coloration in the reduced state, which differs from the usual dark blue of the PEDOT polymer. Finally, the morphology was analyzed using AFM and SEM, and pillar structure of broccoli-like particles was observed for both films. However, the fullerene doping generated smaller polymer-based particles, thus forming a denser structure with higher surface area, suggesting the use of the cages as nucleation points for the polymerization ; AXA Research Fund, the Spanish Ministry of Economy and Competitiveness MINECO (project CTQ2016-76721-R), the University of Trieste and Diputación Foral de Gipuzkoa program Red (101/16) are gratefully acknowledged for financial support.
