Spray deposition and inkjet printing are emerging methods for creating conductive coatings using nanostructures. This study compares the conductive properties and sintering behavior of films made from different nanostructures to reference films made using established techniques. The results show that nanowire-based films have high conductivity, while nanoparticle-based films require higher sintering temperatures.
Spray deposition and inkjet printing of various nanostructures are emerging complementary methods for creating conductive coatings on different substrates. In comparison to established deposition techniques like vacuum metal coating and lithography-based metallization processes, spray deposition and inkjet printing benefit from significantly simplified equipment. However, there are number of challenges related to peculiar properties and behaviour of nanostructures that require additional studies. In present work, we investigate electroconductive properties and sintering behaviour of thin films produced from nanostructures of different metals (Ag, Cu and CuAg) and different shapes (nanowires and spherical nanoparticles), and compare them to the reference Ag and Cu magnetron deposited films. Synthesized nanostructures were studied with transmission electron microscopy. Morphology and crystallinity of produced metal films were studied with scanning electron microscopy and X-ray diffraction. The electrical parameters were measured by the van der Pauw method. All nanowires-based films provided high conductivity and required only modest thermal treatment (200 degrees C). To achieve sufficient sintering and conductivity of nanoparticles-based films, higher temperatures are required (300 degrees C for Ag nanoparticles and 350 degrees C for Cu and Cu-Ag nanoparticles). Additionally, stability of nanowires was studied by annealing the samples in vacuum conditions inside a scanning electron microscope at 500 degrees C.
