“…This is probably due to the very inert local atmosphere when compared to the film (experiment D). This was also observed for other copper compounds (with long alkyl chains) in N2 at 500 °C [51].…”

The thermal decomposition of CuProp2 in the form of film and powder was studied in different atmospheres by means of thermal analysis techniques (TG-MS, TG-IR, EGA), chemical-structural methods (FTIR, XRD, EA) and computational thermochemistry (VASP/PBE). The decomposition mechanism in terms of volatiles evolved was disclosed with the aid of ab-initio modeling; it was found to be dependent on the gas diffusion in and out of the sample and accelerated by a humid atmosphere. In films, the copper redox behavior showed sensitivity to the residual atmosphere. Finally, the role of the metal center is discussed in the frame of a general decomposition mechanism for metal propionates. Volatile species evolved during decomposition can be detected by means of thermogravimetry (TG) coupled with Evolved Gas Analysis (EGA), which mainly works by infrared (EGA-FTIR or TG-FTIR) or by mass spectrometry (EGA-MS or TG-MS) detection. In fact, by EGA-FTIR and EGA-MS, it was shown that the decomposition of propionates in inert atmospheres involves formation of radicals C2H5• and C2H5CO• (along with CO2) and their recombination to form a symmetrical ketone [20-22]. For longer chain salts such as Ca(II)decanoate, techniques like pyrolysis coupled to gas chromatography (GC) revealed a more complicated scenario where normal alkanes were found along with several symmetrical ketones [23]. For odd chain length of Cu(II)carboxylates like Cu(II)propionate, only MS has been used for the in-situ EGA analysis and 2-pentanone (asymmetrical ketone) was reported to be the main decomposition product [11]. Formation of this asymmetrical ke-tone implies cleavage of a CeC(C]O) bond, instead of the expected CeC(]O) and C(]O)eO bonds. Conversely, no ketones at all were observed for even chain carboxylates of copper(II) [24], mercury(II) [25] and silver(I) [26]. In fact, references [24,25] report on the

“…The third weight loss involves in both the carbonization of the polymer and the thermolysis of Cu-oleate. Two apparent DTG peaks at 445 °C and 545 °C in this temperature range suggests that two different decomposition reactions at least has possibly taken place, including the cleavage of the Cu-O and C-O bonds at the lower temperature and breaking C-H bonds at the higher temperature[44,45]. In brief, the calculated results from TG-DTG coincide with the observed results from FT-IR, demonstrating the perfect surfactant bilayer construction in Cu-oleate and the successful coating with DA-F-resins polymer.…”

“…Organometallic inks have been widely researched as a method to bypass some of the challenges with particle‐based inks by printing chemical precursors that, once printed, react to form solid metals. These inks, also called metal–organic complex inks , self‐reducing inks , or reactive inks , consist of dissolved metal salts, chelating agents, and reducing agents along solvents that adjust viscosity, evaporation rate, and surface tension for DoD droplet stabilization.…”

Phone: þ480 965 4912Reactive metal inks have the potential to replace particlebased inks for printed metals and electrodes. Recent advances in self-reducing silver inks have dropped the reduction temperature from >180 8C down to room temperature. However, most reactive inks are printed at room temperature and sintered at an elevated temperature to achieve good electrical resistivity. In this work, we demonstrate that low electrical resistivity (1.8 mVcm) can be achieved by adjusting solvent selection and printing at slightly elevated temperatures. This work examines the impact of solvent type and substrate temperature on the resulting morphology and electrical properties of silver films printed with a selfreducing silver-diamine ink. We show that morphology, porosity, and media resistivity can be controlled to produce a dense film without sintering. The porosity was adjusted from 93% down to 50% and the media resistivity two orders of magnitude from 180 mVcm down to 1.8 mVcm. The lowest media resistivity was found for a 10:1-EtOH:Ag ink printed at 66 8C. Overall, this process demonstrates that highly conductive silver films can be printed at low temperatures with broad control over morphology and without post-print annealing.Reactive inks print silver with controllable porosity.
