Currently, flexible and wearable electronics are a promising and rapidly developing technology, which in recent decades has attracted great attention from both industry and the academic community. However, now, there are significant obstacles to the implementation of industrial technology and the wide practical application of such systems, one of which is the lack of highly efficient flexible electrodes, as well as other functional elements of a dielectric and semiconductor nature, depending on the purpose of the device.
Well-known laser methods allow creating metal patterns on the surface of polymeric materials: laser-induced deposition from solution (LCLD) and selective laser sintering (reductive SLS). Both methods relate to direct laser writing (DLW) techniques, a common feature of which is the localized interaction of laser radiation with a precursor with the initiation of a given chemical reaction and subsequent deposition of the required material on the surface of the substrate used.
The applicant has extensive experience obtaining metallic structures on the surface of dielectrics in order to create microelectronic devices, as well as sensory platforms that allow the detection of substances such as glucose and hydrogen peroxide. The applicant (Russian researcher) is one of the main developers of the method of laser-induced deposition of metals from solution. The German researcher have extensive experience synthesizing nanomaterials by pulsed laser ablation in liquid (PLAL), achieving the synthesis of metallic, oxide, semiconductor, and organic nanoparticles. Reaching maximum productions of g/h, feasible to fulfill industrial requirements. Besides, the group has achieved the synthesis by laser sintering of micro-structured magnetocaloric materials from laser generated nanoparticle inks deposited on glass substrates.
This project is aimed at investigating the fundamental processes occurring during laser-induced metal reduction processes in deep eutectic solvents, an innovative process currently under development and promising towards the synthesis of 2D sensors and electronic devices. The background on deep eutectic solvents synthesis and processing from the Russian group together with the laser and nanoparticle expertise from the German group, makes possible to carry out an interdisciplinary study towards the study of the influence of different laser systems in order to develop simple and effective synthetic approaches.
