제목 Newly-Designed Cu/Cu10Sn3 Core/Shell Nanoparticles for Liquid Phase-Photonic Sintered Copper Electrodes: Large-Area, Low-Cost Transparent Flexible Electronics
초록   In this study, we demonstrate newly-designed core/shell nanoparticles, in which the Cu10Sn3 phase with a low melting point surrounds the internal Cu phase, as an additive material for Cu nanoparticle-based electrodes. The evolution of the liquid-phase by a low-melting point Cu10Sn3 phase facilitates the facile triggering of an efficient densification reaction. This heretofore unrecognized nanoparticle allows for continuous, multi-pulse photonic flash annealing in air even on low-cost, transparent polyethylene naphthalate (PEN) substrates, with the generation of printable electrodes with highly uniform electrical properties, superior mechanical stability, and large-area processability. While the large-area electrodes derived from Cu10Sn3 phase-free Cu nanoparticles suffer from non-uniform characteristics and even a partially insulating nature on vulnerable PEN substrates, the inclusion of Cu/Cu10Sn3 core/shell nanoparticles resolve the uniformity issue in electrical properties and confirmed the practical accessibility for various electronics based on a PEN substrate. The succesful demonstration is given as a touch screen panel and an antenna for wireless power transmission, with the usage of Cu-Cu/Cu10Sn3 nanoparticle mixuture.
